Java: Exception Handling + Process Endin's.
1) I'm just having trouble figuring out what's wrong.
2 *If a mod closes this... just ban me from site , christ.
I seriously remember helping people with "homework" countless times - and this isn't even that. This, SHOULD be working, actually, but it isn't.
I have this simple program, with three classes; Starter contains the main, which does nothing but initialize the UserInput class. Inside the UserInput class is where I'm having the problem. Basically, where it throws the exception, it is ending the process, despite catching it. How would I modify this so that the exception gets handled, and the process continues?
public class Starter{
public static void main(String[] args){
UserInput ui = new UserInput();
}
}
And:
public class StringTooLongException extends Exception{
public StringTooLongException(){
}
public String getMessage(){
return "String has more than the max allowed characters.";
}
}
And:
import java.util.Scanner;
public class UserInput{
public UserInput(){
try{
String done = "DONE";
System.out.println("Type a string. Max 20 characters.");
System.out.println("Type DONE, in all caps to end.");
Scanner scan = new Scanner(System.in);
String s = scan.next();
while(s.compareTo(done) != 0){
if(s.length() > 20){
/**
* Here is the problem, it is ending the process,
* when it is obviously catching the exception.
*/
throw new StringTooLongException();
}
System.out.println(s);
s = scan.next();
}
}
catch(StringTooLongException e){
System.out.println(e.getMessage());
System.out.println("Exception caught! Ending program.");
}
}
}
I've tried so many things, and to be honest I'm quite angry -_- , considering I have (basically) the same code in these three classes:
import java.util.Scanner;
public class Starter {
public static void main(String[] args) {
String done = "DONE";
System.out.println("DocType? U = Unclassified, C = Confidential, P = Proprietary.");
System.out.println("Type DONE, in all caps to end.");
Scanner scan = new Scanner(System.in);
String docType = scan.next();
while(docType.compareTo(done) != 0){
Document doc = new Document(docType);
System.out.println(doc);
docType = scan.next();
}
System.out.println("Program Fin~");
}
}
And:
public class Document {
private String dType = "U";
public Document(String docType){
try{
if( docType.compareToIgnoreCase("U") != 0
&& docType.compareToIgnoreCase("C") != 0
&& docType.compareToIgnoreCase("P") != 0 )
throw new InvalidDocumentCodeException();
dType = docType;
}
catch(InvalidDocumentCodeException e){
System.out.println("Exception caught and handled! Continuing...");
System.out.println(e.getMessage());
}
}
public void setDocType(String docType){
dType = docType;
}
public String toString(){
return "Document type: "+ dType.toUpperCase();
}
}
And:
public class InvalidDocumentCodeException extends Exception{
public InvalidDocumentCodeException(){
}
public String getMessage(){
return "Document code must be U (Unclassified), C (Confidential), or P (Proptietary)." +
"\nDocument will default to Unclassified.";
}
}
Thanks muchly! :/

When an exception gets thrown, it immeadiately skips to the Catch, which is at the end of your program, so it terminates the program cause there's no following lines of code
program is doing what you made it to do lol

Belgium9947 Posts
wow i get more and more convinced you have no idea what you're doing and just copy pasted shit or something
i mean, your catch block is:
catch(StringTooLongException e){
System.out.println(e.getMessage());
System.out.println("Exception caught! Ending program.");
}
you even print that you're ending the program and you dont want it to end the program?

Firstly, the throw is inside a while loop. What I'm wondering is why the crap it isn't continuing the while loop, opposed to what it does now; which is ends the program. It should not be ending the program, it should be throwing an error, catching it, and then going back to the while loop.

Oh noes, I has a random print line that hasn't been changed from a previous version. Printing text doesn't end a program. ... (At least not this one)

If you're talking about this one the exception keeps going up the stack until it gets caught or the program ends, thus its getting out of the while loop.

Your catch block is outside of the while loop, so it doesn't continue in the while loop after it executes the catch block. Java does not magically read your mind. This wasn't supposed to work. This isn't some obscure error. This is you skipping through whatever 'How to handle exceptions' guide you read, copy pasting some stupid shit that you don't understand, and asking tl to fix your errors.

^yes, but your catch block is outside the while loop. It's the same as if you would have used goto in C.
edit: Rage pre-empted me

I dont understand this program does exaclty what you want imo. LOL.

HOE I have a suggestion to make life easier to you:
Identation: helps to find easily where your code blocks belong, I hate to see a code that ends in 3/4 brackets and I dont know where the fuck they belong.

Maybe you should learn Java before you post. You can't put catch statement inside a try statement. Idiot.

It does what it fucking does, and I don't understand why it's ending instead of continuing.
And again, catch can't go inside a try.

Dude, no one is saying that the catch should go inside the try. If you want the while loop to continue, then the catch should go inside the while loop. Why don't you read what people write? Try is not a loop.

First of all: Tell me where I tell you to put your catch block inside your try block? Right, no where. You're the one that doesn't know where to put it, not me.
Secondly: Don't tell me to go learn some Java when you're learning the basic shit yourself and don't even realize how retarded all your previous statements were.
Lastly: Can you please tell me who the fuck you're sharing your account with that is making these dumbass statements? Apparently your IP has been static for days, and now it changes for every post you make about this problem.
Abusing your forum regular status to get answers for a friend that's apparently retarded. Way to fucking go.

Woot. Fixed! Learn English guys. Jesus christ. If you meant to put the ENTIRE TRYCATCH inside the while loop, then that'd have been nice. w00t@Abysdos being helpful, printStackTrace actually made me compare the two programs I had, and whee.

Hay RaGe why so cry to Nam instead of to me?

no
obviously we meant put the try statement both inside and outside the while loop, and the catch statement should be in another program altogether.
HOW COULD WE BE SO UNCLEAR!

Cause if you still don't understand what I wrote, you still don't understand how it works.
See you back when your next homework is due, cause I don't see you comprehending anything anytime soon.
edit: I mean, looking back, do you understand why your previous code didn't work? Why you needed to change the location of your try and catch blocks?
The mistake you made was assuming when an exception is thrown, after the catch block is executed, it resumes in the try block (which would completely ruin the function of try-catch blocks btw). I corrected that by literally saying it resumes after the catch block.

JESUS CHRIST, THAT'S EXACTLY WHAT I ASKED AT THE TOP?
ME:

Notice how I said "I'm wondering why ..." ? The first time I put trycatch inside a while loop I got a fucking runtime error in Eclipse.
ALSO IT'S NOT FUCKING HOMEWORK. IT'S HELP IN UNDERSTANDING. Fuck off.

o noz lets not even address any points of his new post and just ban him

i dunno maybe you should take the time to properly indent the code if you want people to take the time to read it. might want to give it some white space too

Your problem is this is wrong. That's not how try/catch loops work. That is exactly what RaGe pointed out in his first post.
1) try <something>
2) throw exception
3) catch exception
4) execution continues after try/catch block

I'd assume he's talking about Rage's second post, which is a small bit on the offense, however, the way the OP handled it from there... /facepalm

rage's first post answered the OP perfectly, shouldve just been closed after it >.>

Yes I agree Rage escillated it unprovoked. But it's pretty obvious that:
1) You martyr yourself in the first post (slap to moderators' face).
2) It's obviously homework.
3) You don't know what you're doing.
Had you approached with humility and addressed the above three points, we wouldn't be in this situation. Yes, Rage should have been more forgiving and not attacked you/your friend, but after being clearly proven wrong your friend degraded into just insulting everyone. That doesn't fly here.

If you're only using the try/catch block to look for StringTooLongExceptions before printing the input string, you can do this without obfuscating the code by using continue.

public class UserInput{
public String done= "DONE";;

System.out.println(e.getMessage());

Note that I'm not familiar with the Scanner class, but it doesn't look like it should throw exceptions based on your code. Given that, there is no reason to use a try/catch block.

Seriously, almost the entire TL.net community is fucking trash, including the mods. Seriously, why was Kawaii so pissed about this pathetic site.

There will be no more accounts (other than this one)? This site was trash the first time I used it, and it was again, even on Nam's account when I was extremely fucking GM. First some pathetic piece of shit mod closes the first thread, and then I get lawl'd by RaGe, who gains a fuckton of retards behind him? Seriously, you people need to burn at the stake.

Yes I agree Rage escillated it unprovoked. But it's pretty obvious that:
1) You martyr yourself in the first post (slap to moderators' face).
2) It's obviously homework.
3) You don't know what you're doing.
Had you approached with humility and avoided the above three points, we wouldn't be in this situation. Yes, Rage should have been more forgiving and not attacked you/your friend, but after being clearly proven wrong your friend degrading into just insulting everyone. That doesn't fly here.
3)He didn't even have a chance to explain what he understands and RaGe shits all over him on it?
2)How is trying to understand something homework- we already posted the code, hell we fixed it as well.

Maybe you should stop being so defensive and read the fucking solution for a change.
I can't even program and I understand what Rage says. Exception thrown = goto catch. Your friend doesn't address this point at all. So Rage says l2read.

Yeah, I told him in IRC that using an exception is excessive there. It's a simple while loop that takes input and prints it back out.

If you're talking about this one the exception keeps going up the stack until it gets caught or the program ends, thus its getting out of the while loop.

Stop fucking martyring yourself. No one gets banned for have rational discussion about moderators.
Rage attacked unprovoked when he shouldn't have; I've already admitted that. However, your friend is much more at fault in this case. And being that he has literally nothing to add and if flaming many people, he is banned.

Rage's first post is literally everything you need to know. "Didn't help"? If you mean he didn't post the updated code, then sure, but he posted the reason your code wasn't doing what you expected, and everyone can clearly understand it.

That's nice, Chill. Nowhere was it explained that it doesn't go back to where the throw was. Which is the exact fucking opposite of what my "Teacher" had told / shown us inside a fucking powerpoint presentation.

If you stopped lying and admitted that you're not working with him on his 'project' and that you have no clue about Java, you would understand that he just copy pasted that entire catch block in to an arbitrary point in his code and was wondering why it didn't work. The reason why my second reply stated this in a little hostile manner is because after your first thread getting closed, you repost it with a question about he a subject that was clearly not even studied. If he read a basic guide on Exceptions, he would've known what I posted in my first solution.
So, what he basically did was:
1. Copy paste code without understanding how it worked.
2. Being puzzled at why it doesn't work, he posted a thread asking for the fix instead of asking for an explanation.
3. Gets his thread closed. Still doesn't think he should actually try researching what he's doing, and reposts in an aggressive way.
I still post the right answer. Then I realize all this and get a little frustrated and post this:
wow i get more and more convinced you have no idea what you're doing and just copy pasted shit
What he does?
4. Denies my completely valid explanation.
5. Starts flaming people.
How can you even defend this?
