)

Hotkey articles:
Template: Alt + / Modify at: Window -> Preferences -> Workbench -> key -> Edit -> auxiliary content. personal habit:
Shift + SPACE (blank). Simple explanation: When editing program code, hit sysout + Template start button, it will automatically appear:
System.out.println ();. Template set of formats: Window -> Preferences -> Java-> Editor -> Templates. Program code automatically
Typesetting: Ctrl + Shift + F modified at: Window -> Preferences -> Workbench -> key -> program code -> format. Personal habits: Alt + Z. from
Dynamic layout setting: Window -> Preferences -> Java-> code format the program production process. Style page -> to insert tab (not the spacebar) within
Shrink, uncheck this option, the number of spaces to fill below 4, so that when the automatic layout will be a space for indent 4. Rapid implementation of the program: Ctrl +
F11 personal habits: ALT + X to modify at: Window -> Preferences -> Workbench -> Key -> Execution -> to start the job once before starting. Simple instructions
: The first execution, it will ask you execution mode, Set up, after just press the hot key, it will fast execution.

Import Assuming we do not have any class, when we scored in the program:
BufferedReader buf =new BufferedReader(new InputStreamReader(System.in));
Eclipse will this time warning that there is no import category, then we just press Ctrl + Shift + O, it will automatically help us Import category.

Part cheats: a simultaneous switching Eclipse, English, traditional and simplified show:
1. First you have finished installing the culture packages.
2. On the back of a desktop shortcut to add parameters to, English -> -nl "zh_US" Traditional -> -nl "zh_TW" Simplified -> -nl "zh_CN".
(Other languages and so on) 2.1.2 I like culture, I joined the parameters -n1 "zh_US" In my desktop shortcut of Eclipse.
"C: \ Program Files \ eclipse \ eclipse.exe" -n "zh_US" the interface will change back to English language chatter. Use Eclipse, in Word
It may not be necessary to rearrange the program code when editing instruments: the program code Eclipse editing area of the entire copy down (Ctrl + C), direct
Paste (Ctrl + V) to
the Word or WordPad, you will find the program code in Word format, and exactly the same as the set of Eclipse, including fonts, indent
, Keyword color. I have tried JBuilder, GEL, NetBeans ... use the copy and paste, only indented formats, fonts, colors
And so it will not change.
Eclipse-Java Editor optimum settings: Editor font settings: Table -> Font -> Java editor text font.
(Recommended setting Courier New -regular 10) related settings editor: Window -> Preferences -> Java-> Editor Appearance: a display line number
Emphasis display symmetrical square brackets, highlighting the current line, displays a print margin, it is checked, Tab width set 4, the print field is set stitch 80
. Program code assist: mining can be preset. Syntax: Keywords can be set, the display color of the string or the like. Note: mining can be preset. Entry
: All fields are checked. Floating Description: mining can be preset. Navigation: mining can be preset. Discharged from the automatic typesetting effect, in line with most Java
Design practice setting: automatic layout setting: Window -> Preferences -> Java-> program code production format. Wrap: All is not checked. Minute
Line: Line length limit set: 80. Style: only after the mandatory transition insert a blank check. The number of spaces in the shrink: Set 4.
- Control-Shift-T: Open Type (Open type). If you did not mean to make hay, or forgotten through the source tree (source
tree) to open the way to it.
- Control-Shift-R: Open resource (not just to look for Java files). Tip: Use the Navigator view of the yellow two-way
The arrow buttons let you edit window and navigation associated. This will let you open the corresponding file is displayed in the hierarchy navigator, thus
To organize information. If this affects the speed, just turn it off.
- F3: Open declare (Open declaration). Alternatively, using the Declaration Tab (view in the Java mode, select
Windows -> Show View -> Declaration). When you select a method of code, then press this button, it will whole

After use F3 to jump, it is particularly useful. (To return to the original place compiled)

Alt-right arrow: forward navigation history.

Control-Q: Back to the last place in order to edit. This shortcut is when you jump in the code used. Especially when you drill too
Deep, forget what to do when you initially.
- Control-Shift-G: Citations in the workspace (reference). This is a prerequisite for reconstruction. For the method, this hotkey
And F3 is just the opposite effect. It allows you to stack method, up to find all callers of a method. A related feature is turned on
"Tagging" (occurrence marking). Select Windows-> Preferences-> Java-> Editor-> Mark
Occurrences, check the option. Then, when you click on an element of the code in the presence of all the elements in place will be significantly highlighted
Shows. I personally only use the "mark local variables" (Mark Local Variables). Note: Too many highlight will slow down Eclipse
。
- Control-Shift-F: The coding style set reformatting code. Our team have a unified code format, we put it in
On our wiki. To do this, we open Eclipse, select Window? Preferences? Java? Code Style, then set
Code Formatter, Code Style and Organize Imports. The use of export (Export) function to generate a configuration file. We put
These profiles on the wiki, then the team everyone into their Eclipse.
- Control-O: Quick summary (quick outline). With this shortcut, you can quickly jump to a method or property, only
You need to enter the first few letters of the name.
