package day05.cardGame; import java.util.Scanner; public class CardGame { static int[] twoHandsCards=new int[6]; static int userAMoney=0; static int userBMoney=0; public static void main(String[] args) { Scanner s=new Scanner(System.in); System.out.println(\请输入总赌本：\ userAMoney=s.nextInt(); userBMoney=userAMoney; int currentMoney=0;

1，编写程序，判断给定的某个年份是否是闰年。 闰年的判断规则如下：

（1）若某个年份能被4整除但不能被100整除，则是闰年。 （2）若某个年份能被400整除，则也是闰年。

import java.util.Scanner; class Bissextile{

public static void main(String[] arge){ System.out.print(\请输入年份\

int year; //定义输入的年份名字为“year” Scanner scanner = new Scanner(System.in); year = scanner.nextInt(); if (year<0||year>3000){

System.out.println(\年份有误，程序退出！\ System.exit(0); }

if ((year%4==0)&&(year0!=0)||(year@0==0)) System.out.println(year+\ else

System.out.println(year+\ } }

2，给定一个百分制的分数，输出相应的等级。 90分以上 A级 80~89 B级 70~79 C级 60~69 D级 60分以下 E级

import java.util.Scanner; class Mark{

public static void main(String[] args){
