(Java)输入三个整数x,y,z，请把这三个数由小到大输出

public static void main(String[] args){
int num1=0,num2=0,num3=0;
Scanner sc=new Scanner(System.in);
num1=sc.nextInt();
num2=sc.nextInt();
num3=sc.nextInt();
int j;
if(num1>num2){
j=num2;
num2=num1;
num1=j;
}
if(num1>num3){
j=num3;
num3=num1;
num1=j;
}
if(num2>num3){
j=num3;
num3=num2;
num2=j;
}
System.out.println(num1+" "+num2+" "+num3);
}
