Literals in Java

Literals are data that are used for representing constant values.

Java literals are categorized into five types.
• Integer Literals: Whole numbers without precision (decimal points) are called "integer literals."
  Example:

  int num=100;
  

• Floating Point Literals:Numbers with precision (decimal points) are referred to as "floating-point literals."
  Example:

  float num=100.00;
  

• Character Literals:A character enclosed in single quotes is referred to as a "character literal." Character literals are used to represent individual characters.
  Example:

  char a='z';
  

• String Literals:A group of characters enclosed in double quotes is indeed called a "string literal."
  Example:

  String a="hello";
  

• Boolean Literals:A boolean literal is a representation of a boolean value, which can be either true or false.
  Example:

  boolean a=true;
  boolean a=false;
