When to use exceptions in Java (example)

Question

I know that this would be bad practice although I know that I would not be able to explain why.

int [] intArr = ...
...
try{
   int i = 0;
   while(true){
         


        

Answer 1

Reaching the end of an array is not an exceptional case. You know the length before you start looping, so just use a standard idiom.

for(int i = 0; i < intArr.length; ++i) {
    System.out.println(intArr[i]);
}
