Java day04 if-else练习

对输入的三个整形数进行排序（从小到大）

 import java.util.Scanner;
 public class HelloWorld{
	 public static void main(String[] args){
		 Scanner scan =  new Scanner(System.in);
		 int a = scan.nextInt();
		 int b = scan.nextInt();
		 int c = scan.nextInt();
		 
		 if(a >= b){
			 if(b >= c){
				 System.out.println(c + "," + b + "," + a);
			 }
			 else if(a <= c){
				 System.out.println(b + "," + a + "," + c);
			 }
			 else{
				 System.out.println(b + "," + c + "," + a);
			 }
		 }
		 else{ //其实就是 a<=b
			 if(b <= c){
				 System.out.println(a + "," + b + "," + c);
			 }
			 else if(a <= c){
				 System.out.println(a + "," + c + "," + b);
			 }
			 else{
				 System.out.println(c + "," + a + "," + b);
			 }
		 }
		}
 }
