Intellij IDEA generate for-each/for keyboard shortcut

Question

Is there a keyboard shortcut generating a foreach and also for loop?

Answer 1

Pressing Ctrl+J opens the list of live templates within your code context. Then type 'itin'.

Answer 2

You can use Postfix Completion too. Press Ctrl + Alt + S to open the Settings. For example:

int[] list = {1, 2, 3};    
list.for -> for(int i : list) {}

Answer 3

you can use 'live templates' to generate several types of code snippets, loop iteration is done by following -

iter    Iterate (for each..in) 
itin    Iterate (for..in) 
itli    Iterate over a List
itar    Iterate elements of array 
ritar   Iterate elements of array in reverse order 

There are probably many more, just lookup 'Live Templates' in help documentation.

Answer 4

Create for loop from an existing list statement:

1. Highlight the list
2. Cmd+Alt+J or Ctrl+Alt+J
3. Choose Iterate Iterable from the dropdown (i)

There is also plenty of live templates in the internet ! you can just google it.

Answer 6

Aditionally to other answers, you don't even have to use Ctrl + J (but nice for checking what are your possibilities..) Just start type and press Enter:

Foreach: type "iter" then press Enter.

For loop: type "fori" then press Enter.

Idea will recognize the context and suggest the most likely var to iter through, if you like the given options, just press Enters!
