Java Programming Language Keywords
Keywords have special meaning to the Java technology compiler. They identify a data type name or program construct name. Table lists keywords that are used in the Java programming language.
Note – While you might think true and false are keywords, they are in fact Boolean literals, according to The Java Language Specification. Similarly, null is in fact the null literal.
The following are important notes about the keywords:
● The literals true, false, and null are lowercase, not uppercase as in the C++ language. Strictly speaking, these are not keywords but literals; however, the distinction is academic.
● There is no sizeof operator; direct memory access is not possible so the information would be valueless.
● The goto and const keywords are not used in the Java programming language.
