By default is the class name public, private or protected?

what about the data members? and what about the methods?

class test   // by default is the class public,protected or private?
{
    int x =1;  // by default is x public,protected or private?
    
    int getX() // by default is the method public,protected or private
    {
        return x;
    }
}

Hi Junior AX,

All classes are public. If you remove the public modifier, the system still treats the class as public. You can specify other modifiers on the class declaration, such as final and extends.

Instance variables are protected by default.

Hi Junior AX,

Classes and methods are public by default. And global variables are protected by default.

You can easily check it if you create your class and try to access class, method, and variable from another class.

Hi JuniorAX

Variables declared inside the method can be accessed only within this method. Class variables (declared in ClassDeclaration) by default have a protected level.
