Best practices for access modifiers of Java functions
Article Introduction:Best practice for access modifiers for Java functions: Use the most restrictive modifier, which is set to private by default. Inner classes use the private modifier. Protected methods use the protected modifier to allow access by subclasses. All properties in the immutable class are set to private and accessed through getter methods. Public APIs use the public modifier so that they can be accessed by external classes.

FAQ about access modifiers for Java functions
Article Introduction:Access permission modifiers are used to control member visibility. Java provides four modifiers: public (accessible to all classes), protected (accessible to classes and subclasses in this package), default (accessible only to classes in this package) , private (only accessible within this class). According to inheritance rules, subclasses inherit the access rights of the parent class, but cannot expand them. Restricting access to a class or interface can be achieved through the private modifier. The difference between protected and default modifiers is that the former allows access by subclasses and classes within this package, while the latter only allows access by classes within this package.

The relationship between Java function access modifiers and inheritance
Article Introduction:Access modifiers determine the access scope of classes, methods, and fields and play an important role in inheritance: public: Allow access to all classes and subclasses. protected: allows access by classes and their subclasses in the same package. default: Allow access to classes within the same package. private: Allows access only to the class itself that defines the modifier. Subclasses cannot access members of the parent class that use the private modifier. They can change the values of parent class members with the protected modifier. If you do not specify an access modifier, the member will default to default (package scope).

The difference between public and protected access modifiers in Java
Article Introduction:The public and protected access modifiers determine how to access members of a class or method. Modifiers are attached to members when declared. We know that these access modifiers play an important role in Javaoops concepts like encapsulation, polymorphism and inheritance. It helps prevent abuse of membership-provided features. We will try to understand the public and protected access modifiers in Java with a sample program. Access Modifiers in Java Public Access Modifiers Java does not restrict the accessibility of public members. Anything declared as public can be accessed anywhere, which means we can access them inside the class, outside the class, inside the package and outside the package. You may have noticed that in Java

How many non-access modifiers are there in Java?
Article Introduction:Java provides some other modifiers to provide functionality beyond visibility. These modifiers are called non-access modifiers. Static Members declared as static are common to all instances of the class. Static members are class-level members that are stored in class memory. Final This modifier is used to restrict further modifications to a variable, method, or class. The value of a variable declared final cannot be modified once it obtains its value. The Final method cannot be overridden in a subclass, nor can a subclass of the Final class be created. Abstract This modifier can be used with a class or method. You cannot apply this modifier to variables and constructors. Methods declared abstract must be modified in subclasses. You cannot instantiate a class declared abstract. Synchronous This modifier is used to control multiple threads
