If you still put IntelliJ IDEA Use solution to write code like a text editor 、 Run these simple operations , That's a pity ！

IntelliJ IDEA It's very powerful IDE, Open the box , And it includes all the points that developers can improve efficiency in daily life .

Actually , I don't think it's too late to meet 「 skill 」, Just discover those operations that we didn't know originally , And then into their own operating habits , So as to improve the development efficiency .

I think we should maximize IDEA Efficiency and value , It can be downloaded from 3 Starting from all aspects ：

• Built in configuration

• Shortcut key

• plug-in unit

The built-in configuration refers to IDEA There is in itself , But it is easy to be ignored .

Shortcut keys are basically IDEA Built in features , These functions are common to most developers , The problem of inefficiency in the process of mouse click can be avoided through shortcut keys .

Plug ins are some personalized support for different developers , For example, you like Vim Keyboard operation of , That can be used IdeaVim plug-in unit , If you find it troublesome to jump between codes , have access to AceJump plug-in unit .

below , I will introduce you how to play to a greater extent from these two aspects IntelliJ IDEA The efficiency of .

Built in configuration

Suffix completion

Whenever you have an existing expression , You can append a specific suffix after a dot , And use Tab Key to apply it .IntelliJ IDEA Receive expression , And convert it according to the suffix provided .

Join in , You have a list of strings called items, Now you need to traverse it , Follow the routine operation , You should start typing for ..., Write a series of loop traversal statements .

If the suffix is used to complete , You just need to type items.for,IDEA It will automatically recognize for This suffix automatically creates a for-each expression , As shown in the figure below ：

Isn't it very interesting ？ Next try try This suffix suffix ：

It will quickly generate a try-catch expression , It's not very efficient ？

Apart from these two , There are also many suffix completion templates ：

• fori： Iterate through the list through the index

• forr： Use the index to iterate in reverse order

• switch： Generate switch expression

• sout： Use System.out.println Print expressions

• null： Check if the expression is empty

• notnull： Check if the expression is not empty

Through a simple suffix , You can complete a series of expressions , Efficiency has also been greatly improved .

This function was originally used in ReSharper Available in the , And then as a IDEA A separate plug-in for , Later on 13.1 It was introduced as a core function in version IDEA.

In another article, I introduced the usage of suffix completion function in detail , Students who want to know more can have a look ：

Real time templates

First , Come and have a look at , How do you write the following number function ：

public static void main(String[] args) {
 
}


Hit the keyboard word for word ？ Too inefficient ！

4 Things that can be solved with just one letter , Why bother so much ？

All we need to do is IDEA Internal input psvm Then press Tab Key can quickly generate templates

This is the function of implementing templates .

Besides this , There are still a lot of it .

psfs：

public static final String


sout：

System.out.println();


Its usage is a little similar to suffix completion , We can set Editor→Live Templates View currently supported real-time templates , You can also customize real-time templates .

Shortcut key

code

• Ctrl+Space:  Basic code completion

• Ctrl+Shift+Enter:  Complete the current statement

• Alt+Enter:  Quick fix

• Ctrl+Alt+L:  formatting code

• Ctrl+B:  Go to the statement / usage

• Ctrl+Shift+B:  Go to implementation

• Ctrl+U:  Go to super method

• Alt+Insert:  The generated code

• F2:  Next highlighted error

• Ctrl+Alt+V/F/C/P:  Extract variables / Field / Constant / Parameters

• Ctrl+Alt+N:  inline

• Ctrl+F12:  File structure （ for example ： Method list ）

Navigation

• Ctrl+N:  Go to class

• Ctrl+Shift+N:  Go to file

• Shift+Shift:  Search everything

• Alt+1:  Project view

• Alt+F1+Enter: Jump to the file in the project view

• Ctrl+Shift+F:  Find in file

• Alt+Left/Right:  Switch open files

function

• Ctrl+Shift+F10:  Run the current environment

• Shift+F10:  function

• Shift+F9:  debugging

• F7/F8/F9: （ Debug mode ） Get into / skip / Recovery procedure
