Is it normal that i stop getting it?

Answer 1

Where do you stuck? Some ideas are hard to get at first. You should give us some more details.

Answer 2

Methods

Answer 3

You have to describe your problem with some more information. It's hard to get where you stuck, if I have to ask for each word. Do you know about mathematic functions like the linear one f(x)=ax+b? Methods works similar. Whereby f is the name of the func, x is the argument and ax+b is the part of func's body, f(x) is the return value - mostly sublimed to y for a x-y carthesian coordinate system.

-----
public double f(double x, double a, double b)
{
return a * x + b;
}

double y = f(x: 3.0d, a: 1.0d, b: 2.0d); // y = 5

Else, if you meant the execises in this app, please write down it's number. If you stuck, it's possible you did a misspelling something by accident or insert the wrong term in one or more if the multiple choice field.

Answer 4

I think of a method as a function (i.e., equation) within a class (i.e., wrapper).
