使用布尔类型描述成绩

package org.demo;


import java.util.Scanner;

public class Mark {
	public static void main(String[] args) {
		Scanner scanner=new Scanner(System.in);
		int sum=80;//定义李四成绩
		System.out.println("输入张三成绩：");
		int num=scanner.nextInt();
		boolean grade;
		grade=num>sum;
		System.out.println("张三成绩比李四高吗？"+grade);
	}

}
