我希望this.person0和this.person1正常运行，告诉我我不完全了解发生了什么，一位讲师给了我代码，并说修复错误，而我已经进行了不到一个月的编程。所有这些都让我烦恼，修复代码虽然不错，但是解释更好，我曾尝试在此处查看其他答案，但是除非它之间的联系足够紧密，否则我将无法理解。
public class BankApp {
public static void main(String args[]) {
BankApp ba = new BankApp();
class SavingsAccount {
private String Balance;
private String ID;
private String Name;
private SavingsAccount person0;
private SavingsAccount person1;
public void BankApp() {
// A SavingsAccount object cannot be created without an ID, name and an initial balance.
this.person0 = new SavingsAccount("AL01", "Luis Alvarez", 1.00);
this.person1 = new SavingsAccount("BE01", "Elizabeth Blackwell", 2000.00);
// The get... methods are accessors for various private member variables of that object
// Their return types must match the types of the member variables being returned.
System.out.println(person0.getBalance() + " " + person0.getID() + " " + person0.getName());
}
}
}
// The withdraw method takes an amount to withdraw as its parameter.
// Return values:
// true when there are sufficient funds (and when the withdrawal is performed).
// false when there are insufficient funds.
if (this.person0.withdraw(1000))
System.out.println("Done");
else
System.out.println("Insufficient funds");
//The deposit method takes an amount to deposit as its parameter. It does not perform
// the deposit if the value is negative.
this.person1.deposit(1500);
//The transfer method takes a beneficiary SavingsAccount object and an amount as its parameters
// then transfers that amount if sufficient funds are present in the "from" account object.
// Return values: Similar to the withdraw method above.
if (this.person1.transfer(this.person0, 50000))
System.out.println("Done");
else
System.out.println("Insufficient funds");
System.out.println("Balance for " + this.person0.getID() + " = " + this.person0.getBalance());
System.out.println("Balance for " + this.person1.getID() + " = " + this.person1.getBalance());
}
}
}
}
