which are The access Modifier In java?

Final :

• A java variable can be declared using the keyword final. Then the final variable can be assigned only once.

• A variable that is declared as final and not initialized is called a blank final variable. A blank final variable forces the constructors to initialise it.

• Java classes declared as final cannot be extended. Restricting inheritance!

• Methods declared as final cannot be overridden. In methods private is equal to final, but in variables it is not.

• Final parameters – values of the parameters cannot be changed after initialization. Do a small java exercise to find out the implications of final parameters in method overriding.

• Java local classes can only reference local variables and parameters that are declared as final.

• A visible advantage of declaring a java variable as static final is, the compiled java class results in faster performance.
