How do I use private access in Java?

How do I use private access in Java?

In Java, the private access modifier restricts visibility to the class itself. You can declare variables and methods as private.

Can you give me an example of a private variable?

Sure! Here's an example:

class MyClass {
    private int myNumber;

    public void setMyNumber(int number) {
        myNumber = number;
    }
}

What happens if I try to access a private variable from outside the class?

If you try to access a private variable from outside its class, you'll get a compilation error. Private members are not accessible.

How can I access a private variable then?

You can access a private variable through public methods within the class, like getters and setters.
