White space aids not only in separating tokens, but also in formatting the program so that it is easy for humans to read. The compiler ignores the white spaces once the tokens are identified. 51 52 Comments A program can be documented by inserting comments at relevant places. These comments are for documentation purposes and are ignored by the compiler. Java provides three types of comments to document a program: • A single-line comment: // ... to the end of the line • A multiple-line comment: /* ...
