2. Variables in Java

We use variables to store our data
There are some basic data types :

• String :
  We use String to store plain text
  for example : "Java"
  To use String variable first we write String then variable name
  -> String name
  Also we can assign it's value using "=" symbol
  String name = "name" ;


• Integer :
  We use Integer to store whole number like 5 or 85
  To use Integer variable first we write int then variable name
  -> int name ;
  Also we can assign it's value using "=" symbol
  int name = 985 ;


• Float :
  We use Float to store decimal number like 5.5 or 85.9
  To use Float variable first we write float then variable name
  -> float name ;
  Also we can assign it's value using "=" symbol
  float name = 9.98 ;


• Boolean :
  We use Boolean to store true or false
  To use Boolean variable first we write boolean then variable name
