在java语言中,一共有50个关键词,他们都是保留词。
true、false、null都不是关键词,但是他们都是保留词,这些词都不能够在你的程序自行定义。
Keywords 和 Reserved words看来范围是不相同的。 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 |
