for loop

[Ramm Kummar]

Could anyone explian me about the for loop below(commented one)

    

import java.util.*;
class SetTest {
public static void main(String[] args) {
boolean[] ba = new boolean[5];
Set s = new HashSet();
ba[0] = s.add("a");
ba[1] = s.add(new Integer(42));
ba[2] = s.add("b");
ba[3] = s.add("a");
ba[4] = s.add(new Object());
for(int x=0; x<ba.length; x++)
System.out.print(ba[x] + " ");
System.out.println("\n");
for(Object o : s)      // for loop is confusing here
System.out.print(o + " ");
}
}
