Java Fundamentals

Access control modifier and non-access modifier are two types of modifiers in Java.

Access control modifier

There are four access modifiers available in Java, used to set access levels for classes, variable methods and constructor.

  • Scope only inside the same package (default)
  • Scope is visible to world (public)
  • Scope of the package and all subclasses (protected)
  • Scope only within the classes only (private)

Non-Access modifier

There are five non-access modifiers available in Java, used to achieve many other functionalities.

  • Modifier to finalizing the implementations of classes, methods, and variables (final)


class Phone
 final int PRICE_MIN = 999;
 final int PRICE_MAX = 5600;    //final variable
 final void display()   //final method
  System.out.println("Min Price is" + PRICE_MIN);
  System.out.println("Max Price is" + PRICE_MAX );
  • Modifier to create class methods and variables (static)


class Programming {
  public static void main(String[] args) {
  static void display() {
    System.out.println("I love to programming in Java.");
  • Modifier for creating abstract classes and methods (abstract)
  • Modifiers for use in threads (synchronized and volatile)
