You cannot extend a final class. If you try it gives you a compile time error.

what is final in java

Comments(1)

Final is used to apply restrictions on class, method, and variable.
The final class can't be inherited, final method can't be overridden,
and final variable value can't be changed. Final is a keyword

This simple explanation is to all those people who are overwhelmed by
the technical answer proveded by your mentors, google etc... Have fun!!!

                              The key word : "final"
                             
         The final key word is used to declare a variable as constant
         Can be implemented on classes, attributes methods
  
  Example: 
			if i declare a variable like
    			{
     			  int example = 10;
   				}
            i can overwrite it by
            	{
                  example = 20;
                }
			now example is "20".
       //===============================================================  
            final can be used to declare a class , attribute , method 
            as constant throught the program so that they cannot be OVERWRITTEN !!!
            {   
               final int example = 10;
			   example = 20; //this will give an error.
            }

  public void display() {
    System.out.println("This is a final method.");
  }
}

// try to extend the final class
class Main extends FinalClass {
  public  void display() {
    System.out.println("The final method is overridden.");
  }

  public static void main(String[] args) {
    Main obj = new Main();
