int[] nums={1,2,3,4};
for(int i : nums)
for(int j : nums)
System.out.println(i+" "+j+" ");
}

what will be the outcome of the

Compiler error?

[Ashley Waldrop]

I think you missed "}" in the end. If we have "}" in the end then this program will compile and should produce below output(Not in this format )

i=1 and j =1,2,3,4
i=2 and j =1,2,3,4
i=3 and j =1,2,3,4
i=4 and j =1,2,3,4

The "enhanced for" loop, being discussed in this thread, is a variant of the "for" loop, that was added into Java 5. It basically is more of a foreach type of loop -- smart enough to either loop over an array, or via an iterator, automatically.
