How to sort ArrayList in JAVA.

To sort values in ArrayList, we use Collections class, and invoke sort() method. consider this example:

package java8s;

 

import java.util.*;

 

public class SortCollectionDemo {

 

public static void main(String[] args)

{

 

    List li = new ArrayList();

 

    li.add("Santosh");

    li.add("Akshay");

    li.add("Tapuuu");

    li.add("Millan);

    li.add("Rakesh");

 

    Collections.sort(li);

 

for(String temp: li)

{

System.out.println("Countries : "+temp);

}

}

}

Output:

Akshay

Millan

Rakesh

Santosh

Tapuuu
