Answer 1

import java.util.ArrayList;
import java.util.Scanner;

public class ArrayListSort5 {
    public static void sort(ArrayList<Integer> list){
        int i,j;
        int temp;
        for(i = 0;i<list.size();i++){
            for(j = i+1;j<list.size();j++){
                if(list.get(i).compareTo(list.get(j))>0){
                    temp = list.get(i);
                    list.set(i,list.get(j));
                    list.set(j,temp);
                }
            }
        }
    }

    public static void main(String[] args) {
        ArrayList<Integer> list = new ArrayList<>();
        Scanner scan = new Scanner(System.in);
        System.out.println("Enter 5 integers");
        for(int i = 0;i<5;i++){
            list.add(scan.nextInt());
        }

        sort(list);

        System.out.println("Sorted list:");
        for(int i = 0;i<list.size();i++){
            System.out.print(list.get(i)+" ");
        }
    }
}
