生成 Java 类
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
使用 Java 创建接口和类实现。
在对 Cloud 控制台使用不同参数值时,或通过直接调用 Vertex AI API,您可以直接查询模型,并测试返回的结果。
系统指令
您是一名资深 Java 开发者,正在向初级开发者传授知识,因此需要在回答的末尾提供一个段落,总结所生成的代码。
在 Java 中,生成两个类:VenusCard 和 Card。
Card 将是一个包含以下方法的接口:
- 'int pay(int amount, String name)'
- 'int withdraw(int amount)'
- 'int deposit(int amount)'
VenusCard 将是一个实现 Card 接口的具体类。它应执行以下操作:
- 为覆盖面付款创建收据。- 包含 pay() 和 withdraw() 逻辑,以便在余额低于 0 时向所有付款或提款添加 5% 的费用。- 如果某笔交易会导致余额低于透支限额,则应拒绝该交易并返回 -1。

// Define the Card interface
interface Card {
int pay ( int amount , String name );
int withdraw ( int amount );
int deposit ( int amount );
}
//VenusCard class that implements Card interface
import java.util.ArrayList ;
import java.util.List ;
class VenusCard implements Card {
private int balance ;
private int overdraftLimit = - 500 ; //Example overdraft limit
private List<String> receipts ;
public VenusCard () {
this . balance = 0 ;
this . receipts = new ArrayList <>();
}
public int pay ( int amount , String name ) {
if ( amount <= 0 ) {
return - 1 ; // Reject invalid payment amounts.
}
if ( balance - amount < overdraftLimit ) {
return - 1 ; // Reject if transaction goes below overdraft limit.
}
balance -= amount ;
double fee = 0 ;
if ( balance < 0 ) {
fee = amount * 0.05 ;
balance -= fee ;
}
receipts . add ( "Payment of " + amount + " to " + name + " made. Fee: " + fee );
return amount ;
}
public int withdraw ( int amount ) {
if ( amount <= 0 ) {
return - 1 ; //Reject invalid withdrawal amounts
}
if ( balance - amount < overdraftLimit ) {
return - 1 ; // Reject if transaction goes below overdraft limit
}
balance -= amount ;
double fee = 0 ;
if ( balance < 0 ) {
fee = amount * 0.05 ;
balance -= fee ;
}
receipts . add ( "Withdrawal of " + amount + " made. Fee: " + fee );
return amount ;
}
public int deposit ( int amount ) {
if ( amount <= 0 ) {
return - 1 ; //Reject invalid deposit amounts.
}
balance += amount ;
receipts . add ( "Deposit of " + amount + " made." );
return amount ;
}
public int getBalance () {
return balance ;
}
public List<String> getReceipts () {
return receipts ;
}
public static void main ( String [] args ){
VenusCard card = new VenusCard ();
System . out . println ( card . deposit ( 1000 ));
System . out . println ( card . pay ( 500 , "Store A" ));
System . out . println ( card . getBalance ());
System . out . println ( card . withdraw ( 800 ));
System . out . println ( card . getBalance ());
System . out . println ( card . getReceipts ());
}
}
摘要 :代码实现了 Card
接口,该接口定义了基本卡功能(付款、取款、存款)。VenusCard
类实现了此接口,添加了一些功能,例如在余额低于零时对交易收取 5% 的费用,以及透支限额检查,以防止交易导致余额低于定义的透支限额。main
方法提供了一个使用 VenusCard
类的简单示例。添加了错误处理功能,以拒绝无效的交易金额(小于或等于零)。
