I'm trying to understand inheritance better, there's a problem with my bank machine code can you guya take a look at it?

Answer 1

● use static for variable amoutofCash & before method deposit.
//see the error messages there & then try to correct error.

Answer 2

I'm a beginner as well, but as far as I know, you need to create an object of the child class in order to access the methods and variables of the parent class.

BankMachine m = new BankMachine();

m.deposit(37.0);

And you can also make the parent's variables and methods "protected" instead of "private", this way they will be seen only by the child classes.
