实现对三个整数进行排序，输出时按照从小到大的顺序输出。

用户输入三个整数，之后按照整数的大小从小到大输出

import java.util.Scanner;

class Exer1 {
	public static void main(String[] args) {
		
		//输出结果从大到小排序
		Scanner scan = new Scanner (System.in);

		System.out.println("请输入第一个整数：");
		int num1 = scan.nextInt();
		System.out.println("请输入第二个整数：");
		int num2 = scan.nextInt();
		System.out.println("请输入第二个整数：");
		int num3 = scan.nextInt();

		if (num1 > num2){
			if (num3 >= num1){
				System.out.println(num3 + "," + num1 + "," + num2 );
			}else if (num3 <= num2){
				System.out.println(num1 + "," + num2 + ","  + num3 );
			}else {
				System.out.println(num1 + "," + num3 + ","  + num2 );
			}
		}else{
			if (num3 >= num2){
				System.out.println(num3 + "," + num2 + "," + num1 );
			}else if (num3 <= num1){
				System.out.println(num2 + "," + num1 + "," + num3 );
			}else{
				System.out.println(num2 + "," + num3 + "," + num1 );
			}
		}
	}
