This article mainly introduces the use of Eclipse skills, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Optimize eclipse

Eclipse will check the file, syntax format, code, etc., check will often be very performance-consuming, and some we simply do not use, no matter how good tools have 80% of the features are not needed. We can turn off some automatic inspection according to the actual situation, Window-- > Preferences-- > Validation.

I only keep an automatic inspection, you can set up according to the actual situation, turn off automatic inspection, when the need for inspection can be carried out manually, check the required documents, the method is to right-click the file, click validate for manual inspection.

Adjust the eclipse interface

There are many small icons on the eclipse toolbar, using notebook children's shoes, the screen is small, small icons may occupy three lines, your editable area will be small, very inconvenient, but some of these icons on the toolbar, some of which you may not have used once in three or five years, not to mention we have shortcut keys to call it up, right? How to selectively hide and adjust the small icons?

Window-- > Perspective-- > Customize Perspective...

Is it much more refreshing?

Change the font of Eclipse

Change the default font

Window- > Preferences- > General- > Appearance- > Colorsand Fonts-> Basics- > Text Font

Change the editor font

Window- > Preferences- > General- > Appearance- > Colorsand Fonts- > Java- > Java Editor Text Font (default font will be used if you do not change it)

Change the console font

Window- > Preferences- > General- > Appearance- > Colorsand Fonts- > Debug- > Console Font (default font will be used if you do not change it)

Custom shortcut key

Window- > Preferences- > General- > Keys

Select the item for which you want to assign the shortcut key and enter the shortcut key in Binding

Change spell check settings (similar to word's spell check)

Window- > Preferences- > General- > Editors- > Text Editors- > Spelling

Can choose whether or not to Enable spell checking

Custom code template

Window- > Preferences- > Java- > Editor- > Templates

Select the New button to add a new code template

Custom formatting reference template

Window- > Preferences- > Java- > CodeStyle- > Formatter

Eclipse comes with 3 template files, all of which are immutable. We can click the New button to create a new template file so that we can change it.

Have Eclipse automatically generate some methods (such as get and set methods for member variables)

Right-click on the editor panel to select the Source menu item. The menu item that begins with Generate is the option for the system to automatically generate code, such as Generate Getters and Setters. Are get and set methods that automatically generate member variables

Configure the code autoprompt function of eclipse

Window-- > Preferences-- > Java-- > Editor-- > Content Assist

Change the input box content pointed to by the arrow to .abcdefghijklmnopqrstuvwxyz. The reason is that eclipse will pop up an automatic completion window for you to choose only when you type'.'(dot character). This is the default setting, and now it will give you code hints when you type out dots and all the letters. the disadvantage is that the poor performance of the computer may make you doubt your life.

Eclipse Shortcut Keys

Ctrl+1 Quick fix (the most classic shortcut key)

Ctrl+D deletes the current line

Ctrl+Alt+ ↓ copies the current line to the next line (replication increases)

Ctrl+Alt+ ↑ copies the current line to the previous line (replication increases)

The current line of Alt+ ↓ interacts with the following line (especially useful, you don't have to cut and paste first)

The current line of Alt+ ↑ interacts with the previous line (ibid.)

Page previously edited by Alt+ ←

Alt+ → 's next edited page (for the above, of course)

Alt+Enter displays the properties of the currently selected resource (project, or file, or file)

Shift+Enter inserts a blank line on the next line of the current line (where the mouse can be anywhere on the current line, not necessarily the last)

Shift+Ctrl+Enter inserts a blank line in the current line (same principle as above)

Ctrl+Q locates to the last edited place

Ctrl+L is located in a certain line (good news for people with more than 100 programs)

Ctrl+M maximizes the current Edit or View (and vice versa)

Ctrl+/ comments the current line, then uncomment it by pressing

Ctrl+O Quick display of OutLine

Ctrl+T quickly displays the inheritance structure of the current class

Ctrl+W closes the current Editer

Ctrl+K references the selected Word to quickly navigate to the next

Ctrl+E quickly displays the drop-down list of the current Editer (boldface if the current page is not displayed)

Ctrl+/ (keypad) collapses all code in the current class

Ctrl+ × (keypad) expand all the code in the current class

The Ctrl+Space code assistant completes the insertion of some code (but it usually conflicts with the input method, you can modify the hotkeys of the input method, or you can temporarily use Alt+/ instead)

Ctrl+Shift+E displays the manager that manages all currently open View (you can choose to close, activate, etc.)

Ctrl+J forward incremental search (after pressing Ctrl+J, each letter editor you enter provides a quick match to locate a word, if not, it is shown that no one is found in stutes line, which is especially useful when looking up a word.

The function Idea was available two years ago)

Ctrl+Shift+J reverse incremental search (same as above, but from back to front)

Ctrl+Shift+F4 closes all open Editer

Ctrl+Shift+X capitalizes all the currently selected text

Ctrl+Shift+Y lowercase all currently selected text

Ctrl+Shift+F formats the current code

Ctrl+Shift+P navigates to the match for (for example, {}) (when positioning the back from the front, the cursor is inside the match, and vice versa)

The following shortcuts are commonly used in refactoring, so I will sort out the ones I like and often use. (note: generally, the shortcuts for refactoring begin with Alt+Shift)

Alt+Shift+R renaming (one of my own favorites, especially the Rename of variables and classes, which saves a lot of labor than manual methods)

Alt+Shift+M extraction method (this is one of the most commonly used methods in refactoring, especially for a large pile of mud code)

Alt+Shift+C modifies the function structure (more practical, N functions call this method, modify it at once)

Alt+Shift+L extracts local variables (you can directly extract some magic numbers and strings into a single variable, especially if there are multiple calls)

Alt+Shift+F changes local variables in Class into field variables (a more practical feature)

Alt+Shift+I merges variables (it may be a bit inappropriate to say so, Inline)

Alt+Shift+V movement functions and variables (

Regret medicine for Alt+Shift+Z reconstruction (Undo)
