Summary of shortcuts in java

Add necessary comments to make it a good habit for a front-end with a sense of responsibility and a moral model,

This greatly improves the maintainability and readability of the Code.

Java code annotation shortcut: ctrl + shift +/First familiarize yourself with the syntax of html, css, and js Annotations: 1. HTML annotation Syntax:

<! -- Comment content --> 2. css comment syntax

/* Comment */
/* ---------- Text style starts ---------- */3. javaScript comments

// Comment content
/* Comment content */The next step is to summarize the positions used by the annotations in these codes. (May vary according to my habits) 1. Location of html annotation: 1) It is generally used after the end of some major node labels, such:

<Div class = "wrap"> <div class = "main">... </div> <! -- Main end --> <div> <! -- Wrap end --> 2) After the end of some cycles, for example:

<Ul class = "list"> <li> 111111 </li> <li> 222222 </li> <li> 333333 </li> </ul> <! -- List loop -->

2. css comments are generally used on top of a module style to describe which module the style applies to, for example:

/* General-Comment */. comment {...} /* album */. photo {...} /* share */. share {...} /* vote */. vote {...} 3. javascript comments are generally added to a function segment, indicating the function, author, author information, and modification time of the function.

Therefore, when the page is published to the official address, it is best to add an optimization process. Ctrl +/

The following is a list of all shortcut keys in myeclipse: Ctrl + 1 quick fix (the most classic shortcut key, you don't have to say much) Ctrl + D: delete the current row Ctrl + Alt + ↓ copy the current row to the next row (copy added) Ctrl + Alt + ↓ copy the current row to the previous row (copy added) alt + ↓ interaction position between the current row and the following row (especially practical, you can save cutting and pasting) Alt + ↓ interaction position between the current row and the preceding row (same as above) alt + ↓ previous edited page Alt + → next edited page (of course for the above) Alt + Enter displays the current selected resource (project, or file) the Shift + Enter attribute of is inserted with an empty row in the next row of the current row (the mouse can be at any position of the current row, not necessarily the last row) shift + Ctrl + Enter insert blank lines in the current line (same principle) ctrl + Q locate the last edit location Ctrl + L locate in a line (for more than 100 of the program, there will be a good news) ctrl + M maximize the current Edit or View (then press Ctrl +/) Ctrl +/comment on the current row, press Ctrl + O to quickly display OutLine Ctrl + T to quickly display the inheritance structure of the current class Ctrl + W to close the current Editer Ctrl + K to quickly locate the Next Ctrl + e. Quickly display the drop-down list of the current Editer (if the current page is not displayed in) ctrl +/(keypad) collapse all codes in the current class Ctrl + × (keypad) Expand All codes in the current class Ctrl + Space

The Code assistant inserts some code (but it usually conflicts with the input method. You can modify the Input key, or replace it with Alt +) ctrl + Shift + E display the manager that manages all Opened Views (you can choose to close or activate) Ctrl + J forward incremental search (press Ctrl + J, each letter editor you enter provides a quick match to locate a word. If not, it is not found in stutes line. It is particularly useful when you query a word, this Idea feature was available two years ago.) Ctrl + Shift + J reverse incremental Lookup (same as the previous one, but only from the back to the front) ctrl + Shift + F4 close all open Editer Ctrl + Shift + X change all selected text to lowercase Ctrl + Shift + Y change all selected text to lowercase Ctrl + Shift + F format the current Code Ctrl + Shift + P to locate the matching character (for example {}) (When positioning the back from the front, the cursor must be inside the match character, followed by the front, and vice versa)

The following shortcut keys are commonly used in refactoring. I like them and want to sort them out frequently (note: the keys for refactoring generally start with Alt + Shift) alt + Shift + R Rename (one of my favorite ones, especially the Rename of variables and classes, which saves a lot of labor compared with manual methods) alt + Shift + M extraction method (this is one of the most common methods in refactoring, especially useful for a lot of muddy code) Alt + Shift + C modify the function structure (more practical, N functions call this method and modify it once.) Alt + Shift + L extract local variables (you can directly extract some magic numbers and strings into one variable, in particular, during multiple calls) Alt + Shift + F change the local variable in the Class to the field variable (more practical) alt + Shift + I merge variables (this may be a bit inappropriate) Alt + Shift + V moving functions and variables (not commonly used) Alt + Shift + Z reconstruction regret (Undo)

Source code scope function shortcut key Java editor formatting Ctrl + Shift + F Java editor uncomment Ctrl + \ Java editor comment Ctrl +/Java editor add import Ctrl + Shift + M Java editor organization import Ctrl + shift + O Java editor uses try/catch Block to enclose unset, it is too common, so we recommend that you set it here. You can also use Ctrl + 1 for automatic correction.
