need help with java homework

[alfa147x]

im trying to compile this script:

import java.util.Random;



public class BankAccount
{



private double balance;

//Make tank

public tank();
{
balance = 0;


//consturct





}

//deposite

public void deposit(double amount)

{
double newBalance = balance + amount;
balance = newBalance;
}







//Take out

public void withdraw(double amount)

{
double newBalance = balance - amount;
balance = newBalance;
}



//Get balance


public double getBalance()
{
return balance;
}

}


I get this error:

BankAccount.java:14: invalid method declaration; return type required
public tank();
^
1 error
Press any key to continue . . .

Your tank() method requires a return type. It looks like you don't intend on returning anything when the method finishes, so it should look like this (you're forgetting the void keyword):

public void tank() {
balance = 0;
}

Well, read the message... it's complaining because you're defining a method tank() but not saying what that method returns. i.e. Is it supposed to return an integer? A boolean? Nothing at all?

If the idea of "a function returning a value" is not something you're familiar with, then say so and I'll be more explicit.

Also, in your deposit() and withdraw() methods, you don't need to declare a new double variable and then make your balance variable equal to that. I mean it works but it's unnecessary. 🙂

Interesting terminology to say you're trying to compile a java script.
