源代码1：
package banking;
public class Account {

private double balance;

public Account(double init_balance){

balance = init_balance;
}

public double getBalance(){

return balance;
}

public void deposit(double amt){

balance +=amt;
}

public void withdraw(double amt){

balance -=amt;
}
}

源代码2：
package test;
import banking.*;
public class TestBanking {
public static void main(String[] args){
Account account;

account = new Account(500);
account.deposit(22.50);
account.withdraw(47.50);

}
}
运行后，console控制台有反应，无结果？求助ing

没有输出，给你改下
class Account {

    private double balance;

    public Account(double init_balance) {
        balance = init_balance;
    }

    public double getBalance() {
        return balance;
    }

    public void deposit(double amt) {
        balance += amt;
    }

    public void withdraw(double amt) {
        balance -= amt;
    }

    public String toString() {
        return balance + "";
    }
}

class TestBanking {

    public static void main(String[] args) {

        Account account;
        account = new Account(500);
        account.deposit(22.50);
        account.withdraw(47.50);

        System.out.println(account);
    }
}
