i want to create Java program that accepts 3 numbers (num1, num2, num3) and sort them in ascending and descending order.


Example:

Enter num1: 8
Enter num2: 3
Enter num3: 9

Ascending: 3, 8, 9
Descending: 9,8,3

can anyone help me for this

(sorry for my bad English)

There are many sorting algorithms, one of the best one is quick sort and the easiest one is bubble sort. If you are going to have more than 3 numbers to sort, you could imlement one of this algorithms or even better, just use the existing ones: http://java.sun.com/j2se/1.4.2/docs/api/java/util/Arrays.html

However, if you need to sort only 3 numbers you could do something like this:

import java.util.Arrays;

int a, b, c;

int[] arr = {a,b,c};
arr.sort(); // that would sort it in ascending order;

// for descending order visit the link I posted above and you probably will find what you need for descending order ;)
import java.util.*;

public class Sorting {
    public static void main(String[] args){
     
     Scanner sc = new Scanner(System.in);
     TreeSet<Integer> ts = new TreeSet<Integer>();
     for(int i = 0;i<3;i++){
         System.out.print("Enter num"+(i+1)+" : ");
         ts.add(sc.nextInt());
     }

     System.out.println("Ascending : "+ts);
     System.out.println("Descending : "+ts.descendingSet());

    }

}

Try the above code
