A final variable's value can't be changed. final variables should be initialized before using them.
A method declared as final can't be overridden. A sub-class can't have the same method signature with a different implementation.
You should declared your class as final. But you can't define your class as final, if it is an abstract class. A class declared as final can't be extended by any other class.
String and Math are final classes.
final is a modifier which can be applied to a class or a method or a variable. final class can't be inherited, final method can't be overridden and final variable can't be changed.
finally is an exception handling code section which gets executed whether an exception is raised or not by the try block code segment.
finalize() is a method of Object class which will be executed by the JVM just before garbage collecting object to give a final chance for resource releasing activity.
When a method needs to be accessed even before the creation of the object of the class then we should declare the method as static.
A static method should not refer to instance variables without creating an instance and cannot use "this" operator to refer the instance.
Print the statement inside a static block of code. Static blocks get executed when the class gets loaded into the memory and even before the creation of an object. Hence it will be executed before the main() method. And it will be executed only once.
It refers to the currently calling object of the class, mainly used to refer to class members from inside a method when local variable names and member variable names are identical to each other.
It is used to call the base class's method or constructor
