Question

I have code like this:

public class Class1 {

    public void method1() {
        ...
        Class2 c = new Class2(i);
        ...
    }

    public Class1(int i) {
        ...
    }
}

How can I get variable i from constructor to method1 ?

Answer 1

You need to declare a field in the class. E.g.

private int i;

Then in the constructor set this.i = i; You can then access i from anywhere in the class.

To be honest this is pretty basic stuff so Id suggest reading up on Java basics before continuing a project 🙂
