Program: How to rotate elements in the list by specified distance?

Collections.rotate() method rotates the elements in the specified list by the specified distance. After calling this method, the element at index i will be the element previously at index (i - distance) mod list.size(), for all values of i between 0 and list.size()-1, inclusive. This method has no effect on the size of the list.

package com.java2novice.collections;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class MyListRotate {
	
	public static void main(String a[]){
		
		List<String> list = new ArrayList<String>();
		list.add("java");
		list.add("c");
		list.add("c++");
		list.add("unix");
		list.add("perl");
		list.add("php");
		list.add("javascript");
		list.add("ruby");
		list.add(".net");
		System.out.println(list);
		Collections.rotate(list, 3);
		System.out.println("List after rotation:");
		System.out.println(list);
	}
}
