Private Access Specifier Example in Java

Introduction

Private 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. The visibility of the Private access specifier is limited to only for a class where it is defined.

Syntax

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

Private Access Specifier Example Program

public class PrivateAccessSpecifier {
	private static String PrivateMethod(){
		return "This is inside a private method";
	}
	public static void main(String[] args) {
		System.out.println("" + PrivateMethod());
	}
}

Sample Output

This is inside private method

When to use

Use this private 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 Private Access Specifier to confirm the program behaves correctly.

Best Practices

• Use meaningful variable and class names that describe their purpose.
• Compile and run the program locally — modify values to see how output changes.
• Read compiler errors carefully; they usually point to the exact line to fix.

Common Mistakes

• Copying code without understanding each line — practice by changing one statement at a time.
• Mismatching the public class name and the .java filename.
• Forgetting semicolons at the end of statements.
