Here's a list of useful intelliJ shortcuts. You can also refer to the cheat sheet or the intelliJ website.
Commonly used shortcuts
| Action | Shortcut | Remarks |
|---|---|---|
| Quick documentation lookup | Ctrl + J | - |
| View suggested parameters for a function (intellij tool tip) | ⌘ + P | - |
| Inspect element / contents of variables / symbols | ⌘ + mouseover | - |
| Find and select all occurrences in file | Ctrl + ⌘ + G | - |
| Postfix completion | ⌘ + j | to display postfix completion suggestions list( e.g. nn / null, notnull, try, for (this is a forEach shortcut), fori, forr (reverse for loop), synchronised). To see all postfix completion commands, type shift + ⌘ + a and search for ‘postfix completion’] |
| Indentation | Tab (forward) and shift + tab (backward) | - |
| Autofix indentation/formatting | Alt + ⌘ + L | Auto fix all indentation and formatting issues!!! To fix only a certain part, select the lines of the code (or the file or the folder) before running alt + ⌘ + L |
| Code Generator (awesome!!) | ⌘ + N | Select which method you want to generate: (e.g. Constructor, Getter / setter, equals() and hashCode(), toString, super, copyright, etc) |
| Generating Stub test, setUp and tearDown methods | Ctrl + Enter | To auto-generate a test, type Ctrl + Enter to bring up the generator menu, and select Test. A test will be generated, and you can just rename it accordingly. The same can be done for setUp and tearDown |
| Running tests | Ctrl + Shift + F10 | A dropdown menu will show and you can select which test or test class you want to run |
| Rerun last test | Ctrl + F5 | Very useful since we probably want to run the previously run test instead of running all tests every time |
