输入三个整数，并从小到大的顺序输出（java实现）

import java.util.Scanner;




public class zspx {
public static void main(String [] args){
Scanner input=new Scanner(System.in);
System.out.print("a=");
int a=input.nextInt();
System.out.print("b=");
int b=input.nextInt();
System.out.print("c=");
int c=input.nextInt();
int temp;
if(a>b){
temp=a;
a=b;
b=temp;
}
if(a>c){
temp=a;
a=c;
c=temp;
}
if(b>c){
temp=b;
b=c;
c=temp;
}
System.out.println(a+","+b+","+c);


}


}
