Approach

Java

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

public class Collectionssort {
    public static void main(String[] args) {

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

        arrlist.add(12);
        arrlist.add(56);
        arrlist.add(899);
        arrlist.add(65);
        arrlist.add(5);

        Collections.sort(arrlist);

        System.out.println(arrlist);

    }
}

Output:
