In the topic article, I have probably passing the newly introduced language characteristics in J2SE 5.0. In general, Java is also the Java we know, the basic syntax is also some improvements on the original basis. The biggest feeling is that the new features are more or less convenient to write code. It may be necessary to fully accept these new changes for a while, but I think this time the language changes are still developing towards health.
In my personal concern, in these new features, I appreciate the generic, enumeration and annotation, not very static reference, what about you?
Have a friend asked me from JDK 1.4.2 to JDK 1.5.0 (ie J2SE 5.0) transplantation code will not have problems, and the big project has no chance to try, but there is no exception to pass for my toy code. From the perspective of use, I think the JRE of 5.0 should be a good compatible with early Java apps. See the Eclipse these Dongdong, isn't it like a 5.0 environment?
If you have any comments, suggestions, views, welcome feedback.
