编写Java应用程序。首先定义一个描述银行账户的Account类,包括成员变 量“账号”和“存款余额”,成员方法有“存款”、“取款”和“余额查询”。其次, 编写一个主类,在主类中测试Account类的

import java.util.Scanner;

public class YinHang
{
    long zhanghao;
    double yue;
    double ck;
    double qk;
    
    YinHang(long zh,double ye)
    {
        zhanghao=zh;
        yue=ye;
    }
    
    void getcunkuan()
    {
        Scanner sc1=new Scanner(System.in);
        System.out.println("请输入存款数目:");
        double cun=sc1.nextDouble();
        System.out.println("您的存款数目为:"+cun+"元"+"  账户余额为:"+(yue+cun)+"元");
    }
    void getqukuan()
    {
        Scanner sc1=new Scanner(System.in);
        System.out.println("请输入取款数目:");
        double qu=sc1.nextDouble();
        if(qu>yue)
        {
        System.out.println("您的余额不足");
        }
        else
        System.out.println("您的取款数目为:"+qu+"元"+"  账户余额为:"+(yue-qu)+"元");
    }
    double getchaxunyue()
    {
        return yue;
    }
}
