The default way of 1.PackageExplorer display file hierarchy is to list all the packages in parallel, but it can also be displayed as multilevel, and the effect is much better than navigator.
Packageexplorer view, "upper right Arrow →package presentation→hierarchical"
Note:1> do not use navigator, that thing has been abandoned by Eclipse, Packageexplorer specifically for Java customization, various refactoring is quite convenient
2. Clear invalid Imports, "Source→orgnize Imports", file-level, charter, engineering-level support
3. Custom code hints (something like sysout printing System.out.println),
"Window/preferences→java/editor/templates", here it is.
Remember in the base friend computer sysout corresponding output to change to "XXX is a sb Oh,!", haha.
I think eclipse is a pretty cool thing, except that it takes up a bit of memory (more than 400 m in a boot).
But the IDE does a superb job, various refactorings, various searches, various plugins.
The key is open source, OSGi model, well-architected, absolutely worthy of research, the key is also can be customized.
Remember the < build Facebook> said that Facebook's first-class talent must be used to make tools, in this everywhere in the yard of the code farm is the age,
Seemingly do tools is quite able to reflect the geek-diy of the place,!
