You can use Ctrl+1 it will give hints under this you can choose assign statement to new local Variable – Abduce

I see add finally block – Vertigo

try This shortcut it will automatically assign (ctrl+2,l) – Abduce

this shortcut didn't do anything! – Vertigo

shortcuts like "ctrl+2, l" are a bit tricky since it depends a bit on timing here. One approach that works pretty good for me: ctrl down, 2 down (ctrl+2 at that point), release ctrl, L down (2+L at this point), release 2 and L. The cursor will also need to be inside categoryCT.getInsertedItems() since that's what you want to assign. – Wooley

I saw quick assest menu and it also didn't work – Vertigo

Ctrl+1 works even in Netbeans if shortcuts are selected in Eclipse style. – Nickell

Answer 1

Eclipse can't help you with the variable name but you can write:

insertedItems = categoryCT.getInsertedItems();

This will give you a compile error.

If you press Ctrl+1 anywhere in this line, Eclipse will offer "Create local variable 'insertedItems'"

Fewest keystrokes to get the desired result:

• catCTCtrl+Space -> categoryCT
• .getIICtrl+Space -> categoryCT.getInsertedItems()
• ;
• Shift+Alt+Left to select the whole method invocation
• Ctrl+1 + select "Create new local variable"

Shift+Alt+Left to select the whole method invocation Ctrl+1 + select "Create new local variable" these two steps do the job – Vertigo

Answer 2

I'd add for windows users:

Press ctrl+2 for the available options.

For ex. ctrl+2+L will assign your statement to a local variable.

Answer 3

The shortcut that works on my Mac is ⌘2 + l (lowercase L key)

Steps:

• Write the variable, Ex: categoryCT.getInsertedItems();;
• Select the entire variable definition;
• Press ⌘2, leave the press and then press l(lowercase L key);

This will create the line List<Category> insertedItems= categoryCT.getInsertedItems();.

Ctrl+2, L will do what you are looking for.

Answer 5

I don't think I saw Alt+Shift+L, but that works and if your right-hand assignment is the only thing on the line, you don't even have to highlight it

Answer 6

Just uses eclipse's quick fix: Cmd+1. after type categoryCT.getInsertedItems(), then click Cmd+1 when the cursor is at the end.

Answer 7

Alt + Shift + V: in NetBeans Extracts an existing expression or statement into a new variable. For example, the statement appears multiple times so it should be introduced to a variable:

textEmail.getText()

String text = textEmail.getText()

Select statement then the Introduce Variable dialog appears. Introduce Variable dialog Enter the variable name and click OK.

Note that the scope of the newly introduced variable is local.

Answer 8

In IntelliJ IDEA you can use ctrl + alt + l.

Answer 9

for me option+command+L worked on mac with apple chip.

Alternatively, you can select your statement that you want to extract a local variable and right click then from menu options go to refactors and you should be able to find the Extract Local Variable as option.
