Question

0.8 is which literal in java​

Answer 1

Answer:

Any constant value which can be assigned to the variable is called as literal/constant.

// Here 100 is a constant/literal.

int x = 100;

Integral literals

For Integral data types (byte, short, int, long), we can specify literals in 4 ways:-

Decimal literals (Base 10) : In this form the allowed digits are 0-9.

int x = 101;

Octal literals (Base 8) : In this form the allowed digits are 0-7.

// The octal number should be prefix with 0.

int x = 0146;

Hexa-decimal literals (Base 16) : In this form the allowed digits are 0-9 and characters are a-f. We can use both uppercase and lowercase characters. As we know that java is a case-sensitive programming language but here java is not case-sensitive.

// The hexa-decimal number should be prefix

// with 0X or 0x.

int x = 0X123Face;

Binary literals : From 1.7 onward we can specify literals value even in binary form also, allowed digits are 0 and 1. Literals value should be prefixed with 0b or 0B.

int x = 0b1111;

Answer:

Java Literals are syntactic representations of boolean, character, numeric, or string data. Literals provide a means of expressing specific values in your program. For example, in the following statement, an integer variable named count is declared and assigned an integer value.
