In this Java article we want to learn about Java Method Scopes, in Java method scopes determines where a method can be accessed within a program. understanding method scopes is important for writing code that is organized, easy to read and secure. so now let’s talk about this concept in details.
Types of Java Method Scopes
There are four different types of method scopes in Java: public, private, protected and package-private.
Java Public Methods
Public methods are methods that can be accessed from anywhere within a program, including other classes and packages. they are denoted by the public keyword in their method signature, in this example myPublicMethod is a public method that can be accessed from anywhere in the program.

public class MyClass { public void myPublicMethod() { // Code block } } |
Java Private Methods
Private methods are methods that can only be accessed within the same class in which they are defined. they are denoted by private Java keyword in their method signature, in this example myPrivateMethod is a private method that can only be accessed from MyClass class.

public class MyClass { private void myPrivateMethod() { // Code block } } |
Java Protected Methods
Protected methods are methods that can be accessed from the same class, as well as any subclass and any other class in the same package. they are denoted by protected keyword in their method signature.

public class MyClass { protected void myProtectedMethod() { // Code block } } |
Package-Private Methods
Package private methods are methods that can be accessed from the same package, but not from any other package. they are denoted by the absence of any access modifier in their method signature, in this example myPackagePrivateMethod is a package-private method that can be accessed from any class in the same package as MyClass, but not from any other package.

public class MyClass { void myPackagePrivateMethod() { // Code block } } |
