How do you sort numbers in Java program?

Answer 1

Here's simple example to sort numbers in Java using a List:

import java.util.ArrayList;

import java.util.Collections;

import java.util.List;

public class SortTest {

public static void main (String[] args) {

List<Integer> list = new ArrayList<Integer>();

list.add(100);

list.add(1);

list.add(24);

list.add(3);

System.out.println(list);

Collections.sort(list);

System.out.println(list);

}

}

Running it generates the following output:

[100, 1, 24, 3]

[1, 3, 24, 100]
