The private modifier is an access modifier in object-oriented programming languages that restricts access to members (variables and methods) within a class. Private members can only be accessed from within the same class they are declared in.
Think of private members as personal belongings stored inside your bedroom. Only you have direct access to them, and others cannot enter your room without permission. Similarly, private members can only be accessed by methods within their own class.
Public Modifier: The public modifier is another access modifier that allows unrestricted access to members from any other part of the program.
Protected Modifier: The protected modifier grants access to members within the same package or subclasses outside the package but restricts access from unrelated classes.
Default Modifier (Package-private): When no explicit access modifier is specified, members have default access within the same package but are inaccessible from outside the package.
