Protected Access Specifier Example in Java

Introduction

Protected Access Specifier is a classic Java console program that demonstrates the concept with complete source code and sample output. Access specifiers control visibility between classes, packages and subclasses.

This tutorial walks through the program line by line, explains how the logic works, and highlights best practices you can apply in your own code.

Definition

Access specifiers are keywords in object-oriented languages that set the accessibility of classes, methods, and other members. Access modifiers are a specific part of programming language syntax used to facilitate the encapsulation of components. Protected access specifier can be applied to both instance variables and methods. It offers a level of protection intermediate to that offered by the private and public specifiers. Variables and methods declared protected are accessible from the classes defined in the same package and also from subclasses which are defined in other packages.

Syntax

private class class_name{
	//Do something
}
OR
private method_name(){
	//Do something
}

Protected Access Specifier Example Program

public class ProtectedAccessSpecifier {
	protected static String ProtectedMethod(){
		return "This is inside a protected method";
	}
	System.out.println("" + ProtectedMethod());
	}
}

Sample Output

This is inside a protected method

When to use

Use this protected access specifier example when learning or revising core Java syntax.

How it works

1. Execution begins in the main method — the JVM calls this method when you run the class.

2. A println / print call writes text to the console — part of the sample output below.

3. Compare your console output with the sample output for Protected Access Specifier to confirm the program behaves correctly.
