**创建简单的银行账户类，包括开户人、账号和存款余额三个属性，以及查询余额、存款、取款等方法。创建两个账户验证类的设计。**

public class Banks {
        
        public static void main(String[] args) {
        
            bank wang = new bank("ling", 123, 10000);
            bank ze = new bank("hui", 124, 20000);
            bank lon = new bank("he", 125, 3000);
    
            wang.inquire();        //查询余额
            System.out.println();
    
            ze.deposit(5000);      //成功取款5000
            System.out.println();
    
            ze.deposit(20000);     //20000取款失败
            System.out.println();
    
            lon.withdraw(3000);    //存款3000
            System.out.println();
        }
    }
    
    class bank {
        
        String name;
        int num;
        int balance;

                System.out.println("取款成功！");
                this.balance -= a;

            this.inquire();
        }
