❶ java语言程序设计：设计银行账户类，属性包括账号、储户名称、开户时间、身份证号码、存款余额等
写个例子吧，既没有分，又不付费。。。。真的是。。
public class account{
public static int serviceNum;
private String account;
private String password;
......
public String getAccount(){
return this.account;
}
public void setAccount(String account){
this.account = account;
}
public String getPassword(){
return this.password;
}
public void setPassword(String password){
this.password = password
}
public Account(String account,String password){
this.account = account;
this.password = password;
}
public Account(String account){
this.account = account;
}
@overrite
public String toString(){
return this.account + "-" + this.password;
}
}
❷ java定义一个类实现银行账户的概念。
public class BankAccount {
String account ;
int account_num;
//构造函数
public BankAccount(String account,int account_num){
this.account=account;
this.account_num=account_num;
}
//存钱
public String addNum(int num){
account_num= account_num+num;
return "存钱成功";
}
//取钱
public String getNum(int num){
String result;
if(account_num>num){
account_num =account_num-num;
result="取钱成功";
}else{
result="账户余额不足，还剩"+account_num;
}
return result;
}
//显示余额
public String displayNum(){
return "账户余额："+account_num;
}
//显示账号
public String displayAccount(){
return "账户："+account;
}
public static void main(String[] args){
BankAccount lucy = new BankAccount("lucy",100);
BankAccount jack = new BankAccount("jack",50);
//显示他们各自的余额
System.out.println("===显示他们各自的余额===");
System.out.println("lucy:"+lucy.displayNum());
System.out.println("jack:"+jack.displayNum());
//存钱取钱
System.out.println("===存钱取钱===");
System.out.println("lucy取50:"+lucy.getNum(50));
System.out.println("jack存200:"+jack.addNum(200));
//显示账户 显示余额
System.out.println("===存钱取钱===");
System.out.println(lucy.displayAccount()+""+lucy.displayNum());
System.out.println(jack.displayAccount()+""+jack.displayNum());
}
}
运行结果：
===显示他们各自的余额===
lucy:账户余额：100
jack:账户余额：50
===存钱取钱===
lucy取50:取钱成功
jack存200:存钱成功
===存钱取钱===
账户：lucy账户余额：50
账户：jack账户余额：250
