List reversing

In this chapter you will learn:

  1. How to reverse a Java list

Reverse a list

static void reverse(List<?> list) from Collections class Reverses the order of the elements in the specified list.

import java.util.Collections;
import java.util.LinkedList;
import java.util.List;
/*  ja  v  a  2  s  . co m*/
public class Main {

  public static void main(String args[]) {

    List<Character> ll = new LinkedList<Character>();

    for (char n = 'A'; n <= 'F'; n++)
      ll.add(n);

    System.out.println("Here is the original list: ");
    for (Character x : ll)
      System.out.print(x + " ");
    Collections.reverse(ll);

    System.out.println("Here is the reversed list: ");
    for (Character x : ll)
      System.out.print(x + " ");


  }
}
