Prompt key Configuration

By default, Eclipse, MyEclipse's Code hints feature is much worse than Microsoft Visual Studio, primarily Eclipse, myeclipse itself has many options that are turned off by default, to be manually configured by the developer himself. If the developer is not sure, Eclipse is not known, and the MyEclipse Code hints feature is as powerful as the code hinting features of Microsoft Visual Studio.

Let's start with a simple example of the problem, such as in Eclipse, MyEclipse code, playing a foreach,switch and so on, is not able to get the code hint (do not trust themselves to try), the others, not to mention, but in the Microsoft Visual Inside the Studio is a very friendly code hint. In fact, Eclipse, the code hint function in the MyEclipse code is usually the point ".", which is usually a point "." Before a code hint is available.

Principle: "Auto Activation triggers for Java" This option refers to the option to trigger the code hint, change "." To ". ABCDEFGHIJKLMNOPQRSTUVWXYZ (,", It means encountering 26 letters and. (These symbols trigger the code hinting function.) Enhanced eclipse, MyEclipse code hints function, specifically how to configure?

Code hints Setup Steps
    1. opens myeclipse, then window → Preferences
    2. Select Java, expand, Editor, and select Content Assist.
    3. Select "Content Assist" and see the "Auto
      Activation triggers for Java" option under "Auto-activation" on the right, to the right. Actually, it means "." is the trigger code hint. This symbol.
    4. "Auto Activation triggers for Java" option, in the "." After the addition of ABC letters, convenient to find the following changes. Then "Apply" and click "OK".
    5. Then, select any item "File" → "Export", select "Perferences" in the pop-up window and click "Next".
    6. Select the export file path, I export to the desktop, enter "test" as the file name, click "Save".
    7. on the desktop, locate the file you just saved "TEST.EPF", and right-select "Open with Notepad."
    8. can see many configuration myeclipse information
    9. Press "CTRL + F" shortcut key, enter ". ABC" and click "Find Next".
    10. to find the configuration information for ". ABC".
    11. change ". abc" to ". ABCDEFGHIJKLMNOPQRSTUVWXYZ (,", Save, Close "TEST.EPF").
    12. back to the MyEclipse interface, "file" → "Import", in the pop-up window select "Perferences", click
      Click "Next", select just in the modified "TEST.EPF" file, click "Open", click " Finish ". This step
      is similar to the export step above. The
    13. was, of course, a code test. Just create a new project and create a new class. Test in code input Switch,foreach, etc.
      . You will immediately find that the hint, and no matter which letter will have a lot of relevant hints, very flow
      smooth, very convenient.

Summary: The "Auto Activation triggers for Java" option refers to the option to trigger the code hint and "." Change to ". ABCDEFGHIJKLMNOPQRSTUVWXYZ (," means to encounter 26 letters and.) These symbols trigger the code hinting function.

Finally: The automatic prompt pop-up time is best to change to 100 milliseconds or less, otherwise you are finished, automatic prompt to bounce out.

How to use shortcut keys in Eclipse to System.out.println ():

If you do not have a command name named Sysout when you print the SY character, you can customize the string and command name you want to print. Similar (can Key-value) can be customized here windows->preferences->java->editor->templates->new.

prompt shortcut key setting:

Open Window->preference->generate->keys, a large dialog box appears, "alt+/" corresponding to the command name is: "Content Assist", locate the command, click to select it. At this time in the window of the binding and when will appear automatically display the command information, delete the information in the binding, and then press the keyboard alt+/, the binding will automatically display the alt+/shortcut keys, and then when the window select editing Java Source, and finally click OK.

Hint background:

Window--preference--java--editor-completion proposals Background Color recommended 85,90,205

This background color is the legendary protection of the eye background color!

Keyword to configure different colors

Modify the name of the class, interface name, etc., highlighted in different colors

    1. Open myeclipse, then "window" → "Preferences".
    2. This can be configured in "Java" → "Enditor" → "Syntax coloring".
    3. On the right, expand "java" → "classes", tick "Enable" this option, choose your favorite color.

There are, of course, other related color configurations. In fact, in the "Preferences" this thing, there are many things that can be configured, so that Eclipse optimization, specific to each person according to their own preferences to configure.
