index question-arraylist

[pravin kumar]

What will happen when you attempt to compile and run the following code?

import java.util.*;
public class SortList{
public static void main(String argv[]){
new SortList();
}
SortList(){
ArrayList<String> al = new ArrayList<String>();
al.add("z");
al.add("b");
al.add("c");
Collections.sort(al);
for(String element : al){
System.out.print(element);
}
}
}


Answer is dcz ..please explain

I assume you mean bcz. There is a method call Arrays.sort(al) that will sort the ArrayList.

Oops I mean Collections.sort
