Some experiences using Eclipse3
How to use language packs? IBM has launched the language pack of Eclipse 3.0.1, including German, Spanish, French, Italian, Japanese, Korean, Portugal (Brazil), Traditional Chinese and Simplified Chinese. Here is the download address: http://download.eclipse.org/downloads/drops/l-3.0.1_translations-200409161125/index.php. After downloading, decompress it to the corresponding Eclipse directory. In order to have a complete Chinese environment, you need all downloads. This platform is Chinese, helping documents are Chinese. A small problem: It is possible to decompressing the Eclipse does not appear in the Chinese interface, then you can use the "-nl zh_cn" parameter, or "-clean" parameter to start Eclipse.
How to switch language pack? Perhaps you feel in English after you install the language pack, then you can start the language used when you start Eclipse. Use the "-nl en_us" parameter when Eclipse is started. Of course, you can use the -nl parameter to specify the language supported by the language package. A small idea: Do two Eclipse shortcuts, set different language parameters, such as "-nl en_us", one is "-nl zh_cn", named eclipse Chinese, Eclipse English. So, which shortcut you want to use, you can click which shortcut.
How to force the plugin to take effect? In general, the plugse will automatically identify and load the plug-in after extracting the plugs or features directory. But many factors can cause the plug-in to decompress these directories but do not take effect. A common situation is that as long as you start Eclipse3, then unzip the plugin and then start Eclipse3, it does not load these plugins. At this time, a solution is to use the-Clean parameter when starting Eclipse3. If this method does not, you can delete the Configuration directory in the Eclipse installation directory and then start Eclipse.
How do you not show a JAR package? This is useful, especially when your project has a lot of third-party development packages, it can make your view look more tidy. The method is very simple, but you don't know how it is hard to find :). You can filter with [Package Explorer) [Filter] (Filter) of [Package Explorer). In the upper right corner of the [Package Resource Browser], there is a down-to-top icon, click on it, select [Filter] on the menu that appears, there is a [Name filter mode] on the dialog box, hook it, enter "* .Jar", then there will be no packages. Of course, the filter can also filter it in your needs. Also, not only the package resource browser has a filter, many views also have a filter, just see how you use them.
How to use the [tag appearance] function? Hey, this feature is my favorite. It's great! It has a big role in reading code and understanding the code. There is a icon similar to a pen on the toolbar (very similar to the search icon), called [Mark Occurances). Press it, select variables, methods, exceptions, etc. in your class code, and see what changes. You will find that when you select a variable, the variables appear in this file. The method is also the same, and the method is the same, and the exception is more cool, which methods throw this exception also highlights. At the right box of the editor, some light yellow small boxes appear, which is where you choose the elementality of the elements, you can easily browse them by clicking on these small boxes. Oh, is it very convenient? On the [Premier / Java / Editor / Tag] Configuration plane, you can see the appearance of the marked: type, method, constant, very quantity field, local variable, abnormality, method exit point, viscous, and so on. How about the specific function, huh, huh, you slowly experience it :). Supplement: When the cursor is placed on the return type of the method, all method export points will be highlighted. How to abbreviate the package name? This feature may not be used, or it is not necessarily good. But if you know, when you use it, you will further know how Eclipse is more thoughtful and convenient for programmers. For example, if you have a bag name, it is not neat in [Package Resource Browser] or other views, then you can configure the display method. Such as the package: com.neusoft.icd.demoproject.WebApplication.Module1, you want to use abbreviation cnidwmodule1 to represent it or other form, you can use [Preference / Java / Exterior], use [Compressed all package names] This feature, hook it, enter "1.", then you will be the thumbnail package name. How to use this function, huh, huh, slowly will know :).
The Eclipse platform function is powerful and wonderful. If you know other useful, interesting features, you may wish to communicate with you.
supplement:
Fast Type Hierarchy View
Select Types, Methods, or Packages in the Java Editor and press CTRL T to see the quick type hierarchy view. For methods, you can view all subtypes and hypercaries that provide this method. Repeat Ctrl T to switch between normal type hierarchies and super-type hierarchy views.
Quick Summary Shows Members of Inheritance
Try with shortcuts Ctrl O (or Ctrl F3), and members of the current class inheritance are displayed in the Java editor.
