Literals
A literal is a constant value of a particular type, written the way it would appear in a program.
Here are some examples of literals of different types:
| Type | Sample Literals |
|---|---|
| int | 34, -17, 0 |
| double | 3.42, 12.0, -14.7 |
| char | ‘A’, ‘a’, ‘2’, ‘!’ |
| boolean | true, false |
| String | “apple”, “14”, “a” |
Notice that character literals must be enclosed in single quotes, and string literals must be enclosed in double quotes.
