LITERAL IN JAVA

• A literal is a value that may be assigned to a primitive or string variable or passed as an argument to a method call.
• Literals can be any thing like number, text or other information who represents a value.
• Literals are used with addition to variables.

Below are the different types of literals :-

• Integer literals
• Floating literals
• Character literals
• String literals
• Boolean literals

Integer literals

We can present integer literal in decimal, octal or hexa-decimal. Out of these decimal is default one. To indicate octal, we prefix literal with 0 and for hexadecimal we prefix it with 0x.

eg:- the value 38 can be expressed as following:-

• 38 in decimal
• 038 in octal
• 0x38 in hexadecimal.

Floating-point literals

A floating point literal expressed a floating point numerical value. Floating point number is just as the real number of mathematics, double or float .

The one which is default type while writing a floating point literal is doubel , but we can also specify it by simply putting D(or d) at the end of it.

If we want to specify a literal as float we can simply put F(or f) as suffix in it.

we can also use E for specifying floating point literal in scientific notation.

eg:-

• 3D in double floating point literal.
• 0F in float floating point literal.

Character literals

We can expressed a character literal by simply putting it into a single quotes, like given below. eg:- char E='w'

Boolean literals

The only valid literals at boolean type are true and false. In java unlike c we cant thought that 1 is equal to true and 0 is equal to false. We have to use values true and false for doing this. eg:-

• boolean is Big=true;
• boolean is little=false;

String literals

string literal are always described by double quotes. eg:-

• " " = empty string

• "/ " = string containing

• "Akhil" = string containing 5 character.

• "Akhil" + "pandey" = combination of two string literals.
