How to remove extra comma after the last number in loop

Question

Hi I'm just new at programming java. So I was just stuck in this example code:

for(int i=0; i < something.length; i++){
    System.out.print(i + " ,");
}

So, basically it will print like this for example 0,1,2,3,.But as you can see there is an extra comma after the number. Is there a way to code this? thanks in advance.

Naive solution: only print it if `i != something.length - 1`. — Federico klez Culloca, Oct 28 '21 at 13:58

For example

for(int i=0; i < something.length; i++){
    System.out.print(i + i==something.length-1 ? "":" ,");
}

Thank you so much, it worked. Just made some small adjustments System.out.print(i==something.length-1 ? "":" , "); – Glen Oct 28 '21 at 14:17
