Sorting and Searching using Collection Class in DSA Java

Program 1

import java.util.*;
class TestCollections
{
    public static void main(String args[])
    {
          Scanner scan=new Scanner(System.in);
          List<Integer>mylist=new ArrayList<Integer>();
          int n;
          System.out.println("Enter elements in collection for exit press 0");
            do
            {
                n=scan.nextInt();
                if(n==0) break;
                mylist.add(n);
            }while(n!=0);
          
          
          System.out.println("Before Sorting");
          for(Integer I:mylist)
          {
            System.out.println(I);
          }

          Collections.sort(mylist);
          System.out.println("After Sorting");
          for(Integer I:mylist)
          {
            System.out.println(I);
          }
    }
