IntelliJ Idea FAQs

File menu->settings->colors & Fonts->editor font= song body, size=12, line spacing =1.0

File menu->settings->appearance-> Font name=simsun,size=12

IntelliJ idea is a very good Java editor, beginners can be some of the ways to feel very uncomfortable, just beginning to use when I also feel very unaccustomed, in reference to some online articles here to put my experience written out, I hope beginners can quickly adapt to it, You will soon feel that programming is a pleasure.

Some setup tips after installation:

1. How to display the perfect Chinese: settings->appearance check override default fonts by (not recommended), set Name:nsimsun,size:12

2. How to make the cursor non-arbitrary positioning: settings->editor Remove allow placement of the caret after end of the line.



3: How to display line number: Settings->editor->appearance tab, tick show lines numbers



4. How to make IntelliJ idea move without opening the project file: Settings->general remove reopen last project on startup.

5. Why can't I start Tomcat in IntelliJ idea: Please use the zip version of Tomcat

6. Default code hint and complement shortcut key conflict with Input method, how to solve: Settings->keymap

Copy a shortcut key scheme first.

then expand. As shown in figure:

Select a feature, and then add a new shortcut key

The rest of the function, but also to change, such as the Blue font section above. I just changed the space in the original shortcut key to ";", which is a semicolon, which makes it much easier.

IntelliJ Idea 5.0 shortcut keys

1. Ctrl + Space Complete automatic input of class, method, variable name

This shortcut is I most often use the shortcut key, it can complete the class, method, variable name automatic input, very convenient, now I write the program basically will not complete the input variable name, because there is a tool to help you enter, why do you have to hit the keyboard?

2. CTRL + N (Ctrl + Shift + N) jumps to the specified Java file (other file)

This function is very convenient, at least I do not have to every time in a long list of file list to find I want to edit the class file and JSP file

3. Ctrl + B jump to Definition

4. Ctrl + Alt + right/left jump between edited code locations (forward/backward)

5. Ctrl + Alt + T with * to surround the selected line of code (* includes if, while,

Try catch, etc.)

This function is also very convenient, put the previous to do: ① first write If-else,② and then adjust the code

Indentation format, also pay attention to whether the parentheses match, now use this function to do, more convenient

6. Ctrl + Alt + B jump to method implementation

7. Ctrl + W Press A word to select an action

In idea, the shortcut function is to select the word at the character where the cursor is located, then select the source

The extended area of the code. For example, the statement below

Java.text.SimpleDateFormat formatter =

New Java.text.SimpleDateFormat ("Yyyy-mm-dd hh:mm");

When the position of the cursor is in a string within double quotation marks, the string is selected first, followed by the equal sign

The expression on the right, and then the whole sentence. I usually use it when I make a change to the code.

It is to choose the long compound expression, it is very convenient:)

8. Shift + F1 Displays the specified Java docs in the browser

This should also be a feature that almost every Java IDE has to offer, and not much to say.

9. Ctrl + Q displays Java Docs in the editor window

This is handy-because sometimes just forgetting one of the parameters in a method you've written

Meaning, at this point, and do not want to start a browser to view the Java doc, the benefits of this feature is

Show it.

Ctrl +/Comment/counter-comment The specified statement

It can annotate and counter-annotate the statement you have selected (using a single-line comment symbol "//"),

You can also use CTRL + Shift +/To annotate multiple lines of statements (that is, use the multiline comment symbol "/* ... */")

F2/shift + F2 Jump to the next/previous Error statement

Idea provides a convenient jump between error statements, and you can use this shortcut to

Shortcut jumps between the statements that are faulted.

Shift + F6 provides renaming of methods and variables

I use less of the Refector function provided by idea, compared to the function I use most

of the. For this function there is nothing to say, it is very convenient, try it quickly.

Ctrl + Alt + L format the selected code according to the template

Format your Java code according to the formats set in the template, but unfortunately only the Java files

Valid: (

Ctrl + Alt + I automatically indent the selected code

This function also works when editing JSP files, providing a format code for the top

Functional supplement.

Ctrl + Alt + O optimize import

Automatic removal of useless import statements, pretty good one feature.

Ctrl +/[Jump to end of code block/start

Ctrl+g (jump to the specified line), CTRL+F4 (Close the current edit page), ctrl+f (search), etc.

You can download a PDF of Idea 3.0 Default Keymap on the official website of Idea

Using the habit, you can change the set to your custom keying combination in Option--keymaps.
