Java is object oriented programming language.
The Java programming language was developed by James Gosling from Sun in 1995.
OOPS is a programming approach which revolvs around the concept of "object".
Any entity in the system that can be defined as a set of properties and set of operations performed using entity's property set, is known as object.'
variables are the names of memory locations where we store data.
variable name is any combination of alphabet (a to z or A to Z), digit(0 to 9) and underscore (_).
local variable can declare and defineinside function of constructor block. It cannot access outside of function block.
global variable can declare out side of function block. global variable can acces any where in program, if it is public.
static variable can declare at the class level. No need to create an object to access static variable.
Keywords are reserved words, whose meaning is already known to the compiler.
