不要加01，这里是为了区分

【Account.java】类

package banking;

public class Account {
   

    private double balance;    //银行帐户的当前（或即时）余额

    //公有构造器 ，这个参数为 balance 属性赋值
    public Account(double init_balance) {
   
        this.balance = init_balance;
    }

    //用于获取经常余额
    public double getBalance() {
   
        return balance;
    }

    //向当前余额增加金额
    public void deposit(double amt){
   
        balance+=amt;
    }

    //从当前余额中减去金额
    public void withdraw(double amt){
   
        balance-=amt;
    }
}

【TestBanking】类

package banking;
import banking.*;

public class TestBanking {
   

  public static void main(String[] args) {
   
    Account  account;

    // Create an account that can has a 500.00 balance.
    System.out.println("Creating an account with a 500.00 balance.");
    //code
    account = new Account(500.00);

    System.out.println("Withdraw 150.00");
   	//code
    account.withdraw(150.00);

    System.out.println("Deposit 22.50");
	//code
    account.deposit(22.50);

    System.out.println("Withdraw 47.62");
   	//code
    account.withdraw(47.62);

    // Print out the final account balance
    System.out.println("The account has a balance of " + account.getBalance());
