Java中輸入3個整數並且實現按從大到小排序輸出

import java.util.Scanner;

public class demo3 {

public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("請輸入三位整數:");
int a=scanner.nextInt();
int b=scanner.nextInt();
int c=scanner.nextInt();
int max;
if(a<b){
max=a; 
a=b; 
b=max;
}
if(b<c){
max=b; 
b=c; 
c=max;
}
if(a<b){
max=a;
a=b;
b=max;
}
System.out.println(a+" "+b+" "+c);

}

}
