Teddy I think what happens when you use int[] clone = array, you copy the memory reference instead of the array values, such that any changes to clone will affect array since they change the same address in memory. If you want to just clone the values, you should use int []clone = array.clone() instead which will copy all the values. https://www.geeksforgeeks.org/array-copy-in-java/ | ||

I empathize with your situation as a fellow non-STEM major. I think I might have to start very soon, given that I might have to look into being a technical writer and nowadays 90% of jobs in that field demand at least knowledge in one programming language. | ||

Had to use array.clear() , Java can be dumb. you got some memory issues i dont see how if you declare a new array, you still get the old one in java unless you don't use 'new' | ||

is there a better way to write this? seems ugly + Show Spoiler + public static void swap(int[] array, int index1, int index2) { // int var1 = index1; // int var2 = index2; int var3 = array[index1]; int var4 = array[index2]; array[index1] = var4; array[index2] = var3; } lol nvm i commented out the obviously irrelevant part now, doesnt look too wrong anymore | ||

In pseudocode a = 1 b = 2 c = b b = a a = c Adapt it to your Java needs. | ||

Nw= new arraylist Path.filter.Foreachorderered ->{ List p = methodthatreturnsobject Nw.add(p) p.clear } Shitty pseudo code because I'm on mobile, but that should give you the idea. If I didn't add clear then it just recursively added to itself. | ||

I think that Erasme's saying that you may find that using certain array methods like clone() to be more practical when you have larger data structures, but there's nothing wrong with just copying things over one at a time when you're doing ints. | ||
