How to get my code to display the numbers entered from least to greatest

I am having trouble getting the numbers to go in ascending order from least to greatest.

Enter first integer:6
Enter first integer:1
Enter first integer:5

Case (2)
Enter first integer:9
Enter first integer:7
Enter first integer:2

This is my code

import java.util.Scanner;

  public class AscendingOrder
  {
    public static void main(String [] args)
    {
       Scanner input = new Scanner(System.in);
       
       System.out.print("Enter first integer: ");
       int number1 = input.nextInt();
       
       System.out.print("Enter second integer: ");
       int number2 = input.nextInt();
       
       System.out.print("Enter third integer: ");
       int number3 = input.nextInt();
       
       System.out.println("Order ascending: " + number1 + ", " + number2 + " ," + number3);
 
       
       int temp;
       if(number2 < number1 || number3 < number1)

       {
       
         if(number2 < number1)
         {
               temp = number1;
               number1 = number2;
               number2 = temp;
          }
          if (number3 < number1)
          {
             temp = number1;
             number1 = number3;
             number3 = temp;
           }
           if (number3 < number2)
           {
                 temp = number2;
                 number2 = number3;
                 number3 = temp; 
            }
                       
          }
       }
    }
  

>Solution :

If you really want to sort manually:

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);

    System.out.print("Enter first integer: ");
    int number1 = input.nextInt();

    System.out.print("Enter second integer: ");
    int number2 = input.nextInt();

    System.out.print("Enter third integer: ");
    int number3 = input.nextInt();

    int smallest, middle, largest;

    if (number1 <= number2 && number1 <= number3) {
        smallest = number1;
        if (number2 <= number3) {
            middle = number2;
            largest = number3;
        } else {
            middle = number3;
            largest = number2;
        }
    } else if (number2 <= number1 && number2 <= number3) {
        smallest = number2;
        if (number1 <= number3) {
            middle = number1;
            largest = number3;
        } else {
            middle = number3;
            largest = number1;
        }
    } else {
        smallest = number3;
        if (number1 <= number2) {
            middle = number1;
            largest = number2;
        } else {
            middle = number2;
            largest = number1;
        }
    }

    System.out.println("Sorted integers: " + smallest + ", " + middle + ", " + largest);
}

However, the much simpler solution will be to put the values into an array list and then simply sort them using the Collections.sort method:

public static void main(String[] args) {
        Scanner input = new Scanner(System.in);

        ArrayList<Integer> numbers = new ArrayList<>();
        System.out.print("Enter first integer: ");
        numbers.add(input.nextInt());

        System.out.print("Enter second integer: ");
        numbers.add(input.nextInt());

        System.out.print("Enter third integer: ");
        numbers.add(input.nextInt());
        
        Collections.sort(numbers);

        System.out.println("Sorted integers: " + numbers);
    }
