Common shortcut keys and template configurations in eclipse

The following summarizes some common shortcut keys in eclipse. You don't have to memorize it. In daily development, you can use it when you use it. When you get it, you will remember it. In fact, the most commonly used is just a few.

CTRL + 1 quick fix (the most classic shortcut, you don't need to talk about it)
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 between the current row and the previous row (same as above)
Alt + ↓ previous edited page
Alt + → next edited page (of course for the above)
Alt + enter display the properties of the currently selected resource (project, or file)
Shift + enter insert empty rows 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 edited location
CTRL + l locate in a line (for those with more than 100 programs, there will be good news)
CTRL + M maximize the current edit or view (then press it, and vice versa)
CTRL +/comment out the current row, and then press it to cancel the comment
CTRL + O quick outline display
CTRL + T quickly display the inheritance structure of the current class
CTRL + W disable the current editer
CTRL + k quickly locate to the next one by referencing the selected word
CTRL + E: Click it to quickly display the drop-down list of the current editer (if the current page is not displayed, it is displayed in bold)
CTRL +/(keypad) collapse all code in the current class
CTRL + × (keypad) show all the code in the current class
CTRL + Space Code assistant inserts some code (but it is usually in conflict with the input method. You can modify the key of the input method or replace it with ALT +/for the moment)
CTRL + Shift + e display the managers that manage all Opened Views (you can choose to close or activate them)
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 not found in stutes line. It is particularly useful when querying a word. This function was available two years ago)
CTRL + Shift + J reverse incremental search (the 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 locate the matched character (for example, {}) (when positioning from the front, the cursor must be inside the matched 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 mud 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, especially when multiple calls are performed)
Alt + Shift + F convert the local variable in the class to the field variable (more practical)
Alt + Shift + I merge variables (this may be a bit inappropriate inline)
Alt + Shift + V moving functions and variables (not commonly used)
Alt + Shift + z restructured regret medicine (UNDO)

The Java editor uses try/catch blocks to enclose unset ones, which is too common. Therefore, we recommend that you set them here.
You can also use Ctrl + 1 for automatic correction.

In addition, I will tell you the templates in eclipse, which are very useful.

For example, we often need to "catch exceptions" when developing in eclipse. after hitting the "try" three letters in eclipse, click Alt + /, can automatically complete try/catch statement blocks ,:

This is the role of the template. What if I want to add a "finally" block to me by default when I want to write a "try" Statement block and automatically complete it?

Click windows and preferences in eclipse, as shown in the following figure:

Select "try" and press edit. (You can also press "new" to redefine it)

After saving, try again. Using templates and shortcuts can greatly improve development efficiency. If you want to improve your English proficiency (remember words) or speed up typing. It is not recommended.
