2. Introduction to Java Modifiers
• Modifiers in Java define the scope,
accessibility, and behavior of classes,
methods, and variables. They are categorized
into Access Modifiers and Non-Access
Modifiers.

3. Types of Java Modifiers
• 1. Access Modifiers: public, private, protected,
default
• 2. Non-Access Modifiers: static, final, abstract,
synchronized, volatile

4. Access Modifiers
• • public - Accessible everywhere
• • private - Accessible within the same class
• • protected - Accessible within the same
package and subclasses
• • default - Accessible within the same package

5. Non-Access Modifiers
• • static - Belongs to class, not objects
• • final - Prevents modification
• • abstract - Defines abstract classes/methods
• • synchronized - Ensures thread safety
• • volatile - Variable value may change
unexpectedly

6. Example Code
• public final class Car {
• private static int speed = 100;
• }

7. Benefits of Using Modifiers
• ✔ Ensures data security
• ✔ Optimizes memory usage
• ✔ Supports OOP principles
• ✔ Enables better code management

8. Conclusion
• Modifiers play a crucial role in Java
programming by providing access control,
optimization, and security.
