这是一个简单的银行账户类,它有两个构造函数,其中一个可以接收一个整数参数,用于初始化账户余额。类中有三个公共方法,分别是获取余额的方法 getbalance(),取款的方法 withdraw() 和存款的方法 deposit()。其中,取款方法会检查账户余额是否足够,如果不足则会输出 "Insufficient balance." 的提示信息。这个类还有一个私有成员变量 balance,用于存储账户余额。

import java.util.Comparator; public class BankAccount implements Comparable<BankAccount> { private String name; private double balance; public BankAccount(String name, double balance) { this.name = name; this.balance = balance; } public String getName() { return name; } public double getBalance() { return balance; } @Override public int compareTo(BankAccount other) { if (this.balance < other.balance) { return -1; } else if (this.balance > other.balance) { return 1; } else { return 0; } } public static class CompareName implements Comparator<BankAccount> { @Override public int compare(BankAccount a1, BankAccount a2) { return a1.getName().compareTo(a2.getName()); } } }对代码进行简单的文字阐述
这是一个银行账户类BankAccount,它有两个私有变量name和balance,分别表示账户名和账户余额。它还实现了Comparable接口,可以对BankAccount对象进行比较,比较的方式是按照余额从小到大排序。除此之外,还有一个CompareName静态内部类,它实现了Comparator接口,可以对BankAccount对象按照账户名字母顺序进行比较。这个类可以方便地用于银行账户的排序和查找操作。
import java.util.*;public class BankAccountSimulation { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("请输入顾客数量:"); int numCustomers = input.nextInt(); // 创建顾客数组 Customer[] customers = new Customer[numCustomers]; for (int i = 0; i < numCustomers; i++) { System.out.printf("请输入顾客%d的汇款次数:", i + 1); int numTransactions = input.nextInt(); System.out.printf("请输入顾客%d每次汇款金额:", i + 1); double amountPerTransaction = input.nextDouble(); customers[i] = new Customer(i + 1, numTransactions, amountPerTransaction); } // 随机安排汇款顺序 List<Customer> customerList = Arrays.asList(customers); Collections.shuffle(customerList); // 模拟汇款 BankAccount bankAccount = new BankAccount(); for (Customer customer : customerList) { for (int i = 0; i < customer.getNumTransactions(); i++) { bankAccount.deposit(customer.getAmountPerTransaction()); } } // 显示总金额 System.out.printf("总金额为:%.2f\n", bankAccount.getBalance()); }}class Customer { private int id; private int numTransactions; private double amountPerTransaction; public Customer(int id, int numTransactions, double amountPerTransaction) { this.id = id; this.numTransactions = numTransactions; this.amountPerTransaction = amountPerTransaction; } public int getId() { return id; } public int getNumTransactions() { return numTransactions; } public double getAmountPerTransaction() { return amountPerTransaction; }}class BankAccount { private double balance; public void deposit(double amount) { balance += amount; } public double getBalance() { return balance; }}在这个代码的基础上显示每次汇款完后的总金额
可以在 BankAccount 类的 deposit 方法里面添加输出语句,表示每次汇款后的总金额。修改后的代码如下:
```
class BankAccount {
private double balance;
public void deposit(double amount) {
balance += amount;
System.out.printf("当前总金额为:%.2f\n", balance);
}
public double getBalance() {
return balance;
}
}
```
这样,在每次汇款后,都会输出当前的总金额。
