What Is Java Literals? |
|
Answer» LITERALS correspond to a specific value in your Java program. For example, if you type the number 7 (the literal number 7) in a Java program, Java will treat the value as an int type. If you use the character JC WITHIN single quotes (V), Java will treat it as a char type. Likewise, if you PLACE the literal x within double quotes Ox'), Java will treat it as a String. Depending on the literal you are using, Java provides special rules for HEXADECIMAL, octal, characters, strings and BOOLEAN values. As you will learn, you can force a literal to be a certain type. For example, Java will treat the number 1 as an int. But you can force Java to treat the value as the type long by appending the L character to the literal number: 1L.
