Arrays and enhanced for loops?

Question

Can someone please explain what is going on in this method?

class test{  
public static void main(String args[])
{
   int[] x = new int[4]; 
   int[] xy = new i         


        

Answer 1

Here in the advanced for loop, the int j does not represent the index. Rather it represents the values in the xy[] array. It is not possible to get the index of advanced for loop. If you want index, then you might have to use ordinary for loop. Ex. If you have

xy[]={5,8,3,4};
for(int j:xy)
{
    println(j);
}

then the output would be

5
8
3
4
