输入三个整数x,y,z,如何把这三个数由小到大输出，用JAVA语言编程？

import java.io.*;
public class Count{
public static void main(String[] args) throws IOException{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
int x;
int y;
int z;
system.out.print("Please input first number:");
x = Integer.parseInt(br.readLine());
system.out.print("Please input second number:");
y= Integer.parseInt(br.readLine());
system.out.print("Please input third number:");
z = Integer.parseInt(br.readLine());
//一下算法有点类似于冒泡算法
int a ;
if(x>y){
a=x;
x=y;
y=a;
}
if(y>z){
a=y;
y=z;
z=a;
}
if(x>y){
a=x;
x=y;
y=a;
}
system.out.println("The resault is " + x +"," + y+","+z);
}
}
