Need help implmenting the following Java Class

This is what I have so far, but it is not correct so...

package hmwk3;

import java.util.Scanner;

/** * Write a program that takes three integers * from the command line and writes them in ascending order. * @author Darnesha Randle * */ public class PE04 { public static void main(String[] args) { // Create a new Scanner object Scanner input = new Scanner(System.in); // Prompt the user to enter 3 integers System.out.print("Enter three integers: "); int number1 = input.nextInt(); int number2 = input.nextInt(); int number3 = input.nextInt(); if (number1 > number2) { //swap number1 with number2 int temp = number1; number1 = number2; number2 = temp; if (number2 > number3) { //swap number2 with number3 int temp2 = number2; number2 = number3; number3 = temp2; } System.out.println(number1 + " " + number2 + " " + number3); } if (number1 < number2) { if (number2 > number3) { //swap number2 with number3 int temp3 = number2; number2 = number3; number3 = temp3; if (number2 < number1) { //swap number2 with number1 int temp4 = number2; number2 = number1; number2 = temp4; } } System.out.println(number1 + " " + number2 + " " + number3); } }

}
