SUN的官方解释:
http://java.sun.com/j2se/1.5.0/docs/relnotes/version-5.0.html
Version 1.5.0 or 5.0?
Both version numbers "1.5.0" and "5.0" are used to identify this release of the Java 2 Platform Standard Edition. Version "5.0" is the product version, while "1.5.0" is the developer version. The number "5.0" is used to better reflect the level of maturity, stability, scalability and security of the J2SE.
The number "5.0" was arrived at by dropping the leading "1." from "1.5.0". Where you might have expected to see 1.5.0, it is now 5.0 (and where it was 1.5, it is now 5).
5.0是产品版本号;
1.5是开发版本号; |
