Final method in java

by

In java, final methods are declared with final keyword. We can not override the final methods.

Example

class Show{
    //final method
	public final void show(){
		System.out.println("Inside final method");
	}
}
class FinalMethodTest extends Show{
	//try to override final method
	public void show(){
		System.out.println("Inside overridden final method");
	}
}
public class Main {
	public static void main(String args[]){
		//creating object of FinalMethodTest Class
		FinalMethodTest obj = new FinalMethodTest();
		//method call
		obj.show();
	}
}

Output

Main.java:9: error: show() in FinalMethodTest cannot override show() in Show
	public void show(){
	            ^
  overridden method is final
1 error
