Question about gs2

[PrinceOfKenshin]

Okay well i just started AP Computer Science at my school and we are learning Java and i was wondering if gs2 had a feature java does. And that is the whole implementing classes.

So that if i make a class called getbalance

PHP Code:

public double getbalance(double amount) {
balance =amount;
return balance;
} 


so that in the main method i could do

PHP Code:

public static void main(String[] args) {
System.out.println(BankAccount.getbalance());
} 


so that i call the method getbalance of the object BankAccount and it will return the vaule of balance.

Is it possible to do that with gs2 and how?
