纠正一下:true false null 这几个不是关键字在权威的JAVA的官方网站是这样解释的. 地址:http://java.sun.com/docs/books/tutorial/java/nutsandbolts/_keywords.htmlJava Language Keywords Here's a list of keywords in the Java programming language. You cannot use any of the following as identifiers in your programs. The keywords const and goto are reserved, even though they are not currently used. true, false, and null might seem like keywords, but they are actually literals; you cannot use them as identifiers in your programs. abstract continue for new switch assert*** default goto* package synchronized boolean do if private this break double implements protected throw byte else import public throws case enum**** instanceof return transient catch extends int short try char final interface static void class finally long strictfp** volatile const* float native super while * not used ** added in 1.2 *** added in 1.4 **** added in 5.0
java 关键字 abstract boolean break byte byvalue case class const continue default do double false final finally float for goto if implements import instanceof int interface long native package private protected public return short static super switch synchronized shis threadsafe throw transient true try void while 以上是jdk1.3的关键字
