Using an int from one class in another class

Question

I am a student writing a java program on renewable energy. Simply I have a power output which is a variable called PowerOutPut. declared as (public int PowerOutPut) I have another class which is a graphics class where I display the variable PowerOutPut on a graph, but i dont know how to call this variable in my graphics class.
if anyone can help, I would be very grateful.

Answer 1

But bear in mind that it is good practice to declare your variables private (unless you need otherwise) and to provide get and set methods to access and change them.
private int myVariable = 0;
public int getMyVariable(){
    return myVariable;
public void setMyVariable(int newValue){
    myVariable = newValue;
}Also, class names should start with upper case and variables should start with lower case.
Good luck.
