Eclipse Usage Tips

(i) common Eclipse shortcut keys

(1) Ctrl + left mouse button
Used to view the definitions of variables, methods, classes

(2) Ctrl+o
View a schema for a class that lists its methods and member variables. Tip: If you press Ctrl+o again, you can list the methods and variables that the class inherits.
Mnemonic: "O"---> "Outline"---> "outline"
(3) ctrl+t
look at the inheritance tree of a class , which is top-down, and then press once more ctrl+t, which is replaced by a bottom-up display structure.
Tip: Select a method name and press Ctrl+t to see the parent, subclass, and interface of the method with the same name.
Mnemonic: "T"-------> "tree"-----> "Hierarchy tree"

(4) ctrl+/

Comment on the current line, and then cancel the comment

Attention:

The shortcut key is not valid when editing an XML file.
Eclipse XML Comment: CTRL + SHIFT +/
Undo Comment: CTRL + SHIFT + \

(5) Ctrl+shift+f formatting of the current code

(6) Other shortcut keys

ctrl+/(numpad) collapses all code in the current class

Ctrl+x (keypad) expands all code in the current class

Alt+shift+r rename (is my own favorite, especially the variables and classes of rename, than the manual method can save a lot of labor)

Alt+shift+m Extraction Method (This is one of the most common methods of refactoring, especially useful for a whole bunch of mud codes)

Alt+shift+c Modify the function structure (more practical, there are n functions called this method, modified once done)

Alt+shift+l extract Local variables (you can directly extract some magical numbers and strings into a variable, especially when multiple calls are made)

Alt+shift+f change the local variable in class to a field variable (more useful function)

Alt+shift+z reconstruction of Regret medicine (Undo)

Ctrl+alt+h View the hierarchy of relationships in which a function is called by another function
