Litterls in Java

Data value that appears explicitly in our program are called Java Literals. The literals are stored in the variable's to use for long time.

The literals are comes under different types that could be integer,character,float,boolean,String and null type literals. I have given Example in image of four type literals.Lets take a look of rest types with them.

Integer Literals 
Integer Literals are the number type Literals.Like 2478 and -234 are the example of Integer Literals.
int a=25;

Float Literals
Float Literals are the Float type or real number Literals. 24.277 and -34.343 are example of Float Literals.
float fl=2.23;

Character Literals
Character Literals are Charecter type Literals. In that first you know about the ASCII values.The ASCII Character set include 128 character including the letters and Symbols.

Boolean Literals 
In java programming the 0 and 1 are also treated as literals.Where 0 is for false and 1 is equivalent to the true.
boolean active=true;

String Literals
Any group of charecters call the String Literals.Where the String Literals are the place where you can save any meaning full charecter set like name of a persone.
String name="Shiva";
