Java Literals

A constant value in a program is denoted as literal. e.g., 10, 534, 29.5, 'c', true, false, 'E', '&' are all literals of various datatypes.

In the above statement 10 is an integer literal. Because the value 10 directly represents the integer so, 10 is called integer literal. In Java, these are the various types of literals:

• Integer Literals In Java - e.g., 10, 23, 50, 22202329L, 045, 0x23efa00

• Floating Point Literals In Java - e.g., 0.23, 2.23f, 4.120F, 32424.2112, 221.33D, 9982.11d

• Character Literals In Java - e.g., '(', 'R', 'r', '{'
