Final and Static Keywords in Java

The Keyword Final is used for declaring a class member as constant. The member declared as final cannot be overridden.To prevent a class from being inherited the Keyword Final is used. Initialization of a final variable is done inside a class, but not in the constructor of the class. The class declared as a final cannot be Inherited.
for example:

final class A 
{
    // statements
}
class B extends A
{
    //compile time error as Inheritance of final class is not possible 

}

In the above code the class B can't extends class A as it is a final class.

We cant even override the method of the parent class in inheritance if the function is a final member in the base class.

Static are variable exists outside of any class. They are usually accessed with the class name using the 'dot' operator.Static members of a class can be Static variables, Static Initialization Block and Static Methods. Static members of a class are stored in the class memory and can be access directly.

for example:

class A
{
    static int a = 5;    //Static Field

    static void example()
    {
        //Static method
    }
}

public class MainClass
{
    public static void main(String[] args) 
    {
        System.out.println(A.a);    //Accessing static Field 

        A.example();     //Accessing static Method 
    }
}
