How to change attribute value globally in Java?

I am asking the user to input a value and then I am assigning the same to an attribute but, I want that change to be global. I searched on internet but yet I am not able to find the working solution for it. By the way I m using Java.

Thanx in advance.....

Solution

  • This question has already been extensively covered. If you are looking on how to make a variable global/accessible from outside a class, check here.

    However, if you are looking to make a global variable that can be accessed in and ONLY in a class, you can use the private static Keyword. Here is an example:

    class myClass {

    private static int myGlobalVariable;     //Can only be accessed from methods in myClass

    void changeMyVariable (int value) {
        // Data validation here if needed
        this.myGlobalVariable = value;
    }
}
