Java 输入3个数，找到最大值和最小值输出

import java.util.Scanner;
public class Test {
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
System.out.print(“请输入第1个数：”);
int num=sc.nextInt();
int max=num,min=num;

	for(int i=2;i<=3;i++){
		System.out.print("请输入第"+i+"个数：");
		num=sc.nextInt();
		if(num>max){
			max=num;
		}
		if(num<min){
			min=num;
		}
	}
	System.out.println("max="+max);
	System.out.println("min="+min);
	sc.close();
	
}

}
