1. Ctrl+shift+r: Open Resource
This is probably the most time-saving combination of all shortcut keys. This set of shortcuts lets you open any file in your workspace, and you only need to press the first few letters of the file name or mask name, such as Applic*.xml. The drawback is that this set of shortcuts is not available in all views.
2. Ctrl+o: Fast Outline
If you want to see the methods of the current class or a particular method, but do not want to pull the code down, and do not want to use the search function, then use Ctrl+o bar. It can list all the methods and properties in the current class, you just enter the method name you want to query, and click Enter to jump directly to where you want to go.
3. Ctrl+e: Quick Convert Editor
This set of shortcut keys will help you navigate between the open editors. Use ctrl+page down or ctrl+page up to browse the tabs before and after, but ctrl+e is more efficient when many files are open.
4. Ctrl+2,l: Assigning a value to a local variable
During development, I often write methods, such as calendar.getinstance (), and then assign the results of a method to a local variable by ctrl+2 shortcut keys. This saves me the input class name, the variable name, and the time the declaration was imported. The ctrl+f effect is similar, but the effect is to assign the result of the method to a field in the class.
5. Alt+shift+r: Renaming
Renaming properties and methods was a hassle a few years ago, requiring a lot of searching and replacing so that the code became fragmented. Today's Java IDE provides source-processing functionality, as is eclipse. Now, the renaming of variables and methods is very simple, and you'll get used to renaming each time a better alternative name appears. To use this feature, move the mouse over the property name or method name, press Alt+shift+r, enter a new name, and then click Enter. This is done. If you rename a property in the class, you can click Alt+shift+r two times, this will call out the Source Processing dialog box, you can implement the get and set method of automatic renaming.
6. Alt+shift+l and Alt+shift+m: Extracting local variables and methods
Source processing also includes the ability to extract variables and methods from chunks of code. For example, to create a constant from a string, select the text and press Alt+shift+l. If the same string appears elsewhere in the same class, it is automatically replaced. The method extraction is also a very convenient function. Breaking up large methods into smaller, well-defined methods can greatly reduce complexity and improve the testability of your code.
7. Shift+enter and Ctrl+shift+enter
Shift+enter creates a blank line below the current line, regardless of whether the cursor is at the end of the row. Ctrl+shift+enter inserts a blank line before the current line.
8. ALT + arrow key
This is also a magic weapon to save time. This combination moves the contents of the current line up or down. In the Try/catch section, this shortcut is especially useful.
9. Ctrl+m
Large display screen can improve productivity is known to everyone. Ctrl+m is the shortcut key for maximizing the editor window.
CTRL +. And Ctrl+1: Next error and quick change
CTRL +. Moves the cursor to the next report fault or warning in the current file. This set of shortcut keys I generally use with ctrl+1, that is, modify the proposed shortcut keys. The new version of Eclipse suggestions are good to help you solve a lot of problems, such as missing parameters in the method, Throw/catch exception, non-executed methods and so on.
1, Alt +? or alt+/: Auto-complete code or prompt code
This is my most proud shortcut key combination, especially when the input syso a few characters, 2 fingers easily press the 2 keys, the automatic completion of the SYSTEM.OUT.PRINTLN (), and Eclipse default is "." The method hints, if the middle tip is broken and want to see again, you have to re-enter the corresponding class or variable in front of "." Before you can see the hint, but if the 2 key combination is the same can play the role of the hint, you can try, and if the input for after, if there is a need to traverse the local variables, will pop up to choose with for each traversal or for (int;; ) or while () and then automatically generate the code.
If you want to see the methods of the current class or a particular method, but do not want to pull the code down, and do not want to use the lookup function, it is very useful to use ctrl+o, especially directly open or trace to a very many methods of the class, this is very helpful, directly see those methods and member variables, It can list all the methods and properties in the current class, you just enter the method name you want to query, and click Enter to jump directly to where you want to go.
This is probably the most time-saving in all shortcut key combinations, and I often use it, especially if you find a file directly in the project or workspace by name, this set of shortcuts lets you open any file in your workspace, and you just need to press the first few letters of the file name or mask name, such as applic* . Xml. The drawback is that this set of shortcuts is not available in all views.
The default 80 characters will be wrapped, this can be set. You can also reformat code based on code style, our team has a unified code format, we put it on our wiki. To do this, we open Eclipse, select the window Style, and then set the Code formatter,code style and organize Imports. Use the export feature to generate a configuration file. We put these profiles on the wiki, and everyone in the team is imported into their eclipse.
5. Ctrl+e: Fast Conversion editor
This set of shortcuts will help you navigate between the open editors, especially when many files are open, and the ctrl+e will be more efficient and helpful.
Can browse before and after the tab, if the use of skilled words, the individual page switch will be very fast, feel very good.
Shift+enter creates a blank line below the current line, regardless of whether the cursor is at the end of the row. Ctrl+shift+enter inserts a blank line before the current line. These 2 shortcuts are also very helpful, at first you may not get used to, but after many times, you will feel very convenient, anyway I am.
This is also a magic weapon to save time. This combination moves the contents of the current line up or down. In the Try/catch section, this shortcut is especially useful.
This is also very useful shortcut keys, it is very convenient to copy the current code to the previous line or the next line, I often use.
10. Ctrl+m: Maximize the current edit page windowLarge display screen can improve productivity is known to everyone. Ctrl+m is the shortcut key for maximizing the editor window, and pressing again restores the normal window.
11, ctrl+/: Automatically comment on the current line or select multiple linesAutomatically comment out the current line or multiple lines of code, with//comments, with ctrl+\ can uncomment.
12, ctrl+shift+/: Automatically comment out the selected code block
This note is used with/* */annotated (if it is a programming language code), development is also very useful, html,css, etc. can also use this comment, generate the corresponding annotation tag, with ctrl+shift+\ can uncomment.
Delete the current line, this is very useful, I also often use, especially in debugging, delete the current error, combined with CTRL + Z editor undo shortcut Keys, with ease.
This shortcut key commonly used in the writing of SQL statements, I also often use, it is recommended that all the keywords in the SQL statement are capitalized, although the database case is not differentiated, but this is beneficial to others and their own reading especially SQL statements very long circumstances, and this look is also very normative.
15, Ctrl+shift+o: Automatically introduce the package and delete the useless packageThis shortcut is also very convenient, when we use a class in another package, if the corresponding package or class is not introduced, there will be a red wavy line hint, at this time we can press this shortcut, red hints automatically disappear back to normal, if there are more than one containing the same class, then you will be prompted to choose, If there is no use of the package to introduce the situation, usually the code copied to copy to create more, can also be quickly removed with this key.
Lock Command Line window: In the Command line view (Window->show view->other->basic->console), try using the SCROLL LOCK button to lock the console output without scrolling.
Using Ant view: In my Java or debug mode, I like to show the ant view so I can run the ant task quickly. This view can be found through window ant. Place the ant view in the corner of the screen and add the Build.xml file with the add compiled file (addàotheràshow viewàbuildfiles) button. In version 3.1, even the Ant debug scripting language is supported.
Automatically traverse a collection: For + control-space: If you do not yet know, then you should remember that Control-space is the AutoComplete feature. In Eclipse, you can also automate the structure. In an array or collection range, try entering "for" and then pressing the Control-space key. Eclipse will ask you which collection you want to traverse and automatically complete the loop code.
Using hierarchical layouts: The default layout (flat) In Package Explorer View makes me confused, and it shows the full name of the package in the Navigation tree (navigation). I prefer the package and file system view of my source code, which is called the hierarchical layout (hierarchical layouts) in eclipse. To switch to this mode, click the Down button in the package browse view, select Layout, and then select Rating (hierarchial).
Show multiple files at once: You can browse multiple files at once. You can open an edit window that is not in the active state by dragging it to the bottom of the active window or to the scroll bar on the side. This is the best way I can describe the trick.
Open two eclipse simultaneously: to merge the changes from one CVS branch to another, I like to do this by opening two working directories (Workspace) to different eclipse. This way I can see all the changes by comparing the latest version on CVS (right-click the project and then select Compare lastest from HEAD) and then merge each change into another CVS branch. The simplest way to start multiple eclipse is to take advantage of Eclipseàwith Launcher.
Implementors plugin: Installs a plug-in that can jump to an implementation of an interface. If you're a dependency injection fan, or you're working on an excellent interface, you'll need a plugin like this to speed up code navigation. You can find this plugin in SourceForge.
Automatically generate getter and setter methods: in the corresponding Pojo, right-click on the space, select "Source", then select "Generate Getters and Setters", and then choose which properties you have to generate such a method, click "OK" is OK, Especially in the case of very many member variables, it saves time.

Alt+shift+r rename (is my own favorite, especially the variables and classes of rename, than the manual method can save a lot of labor)
Alt+shift+m Extraction Method (This is one of the most common methods of refactoring, especially useful for a whole bunch of mud codes)
Alt+shift+c Modify the function structure (more practical, there are n functions called this method, modified once done)
Alt+shift+l extract Local variables (you can directly extract some magical numbers and strings into a variable, especially when multiple calls are made)
Alt+shift+f change the local variable in class to a field variable (more useful function)
Alt+shift+i Merge variables (this may be a bit inappropriate inline)
ALT+SHIFT+V moving functions and variables (not commonly used)
