This shortcut key is a good helper for users to edit and can provide content assistance for users. Don't worry about remembering the names of all methods and properties. When you can't remember the names of all classes, methods and properties, experience the benefits of ALT+/ shortcut keys.
2.Ctrl+O
Displaying the outline of methods and properties in a class can quickly locate the methods and properties of a class, which is very useful for finding bugs.
3.Ctrl+/
Quickly add comments. You can quickly add comments or uncomment the line where the cursor is located or the selected line. When debugging, you may always need to comment something or uncomment it. Now, you don't need to repeat the comment for each line.
4.Ctrl+D
Delete the current line, which is also one of my favorites. You don't have to press the delete key so many times to delete a row.
5.Ctrl+M
Maximize and restore windows. Users always feel that the current window is very small when operating the window (especially when writing code). Now, try the Ctrl+M shortcut.
View and locate shortcut keys
In a program, it is not easy to quickly locate code and find bugs. Eclipse provides a powerful search function. You can use the following shortcut keys to help complete the search and location.
1.Ctrl+K、Ctrl++Shift+K
Quickly search up and down the selection, no longer need to click the search dialog box with the mouse.
2.Ctrl+Shift+T
Find the discoverable Java class file in the workspace construction path. Don't worry about not finding a class, you can use "*" and "?" Equal sign wildcard.
3.Ctrl+Shift+R
For Ctrl+Shift+T, find all files (including Java files) in the workspace, or use wildcards.
4.Ctrl+Shift+G
Find references to classes, methods, and properties. This is a very practical shortcut key. For example, if you want to modify the code that references a method, you can use the shortcut key Ctrl+Shift+G to quickly locate all the locations that reference the method.
5.Ctrl+Shift+O
Quickly generate imports. Copying a program from the Internet, I don't know how to import it into the called class. Try Ctrl+Shift+O shortcut keys, and you will be surprised.
6.Ctrl+Shift+F
Formatting code and writing code in standard format is a compulsory course for every programmer. When you see an extremely unpleasant code, select it and press Ctrl+Shift+F to format it. If no code is selected, the current file (Java file) will be formatted by default.
7.ALT+Shift+W
Finding the path of the current file in the project can quickly locate the position of the browser view. This shortcut key is very useful if you want to find the package where the file is located (especially in a larger project).
8.Ctrl+L
Navigating to a line in the current editor is also valid for non-Java files.
9.Alt+←、Alt+→
Backward history and forward history are very useful when tracking code. Users may find several related places, but they may not remember them clearly. You can locate the search order through these two shortcut keys.
10. The third offspring
Classes, methods, and properties that can quickly locate the cursor position.
1 1. tetralogy of Fallot
Displays the inheritance relationship of the class and opens the class inheritance view.
