Generate local variable to receive the return value of a method eclipse

Question

for example I have this code

categoryCT.getInsertedItems();

and I want shortcut to generate code like this

List<Category> insertedItems=   categoryCT.getInsertedItems();

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:

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

Answer 2

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(); .

Answer 3

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 4

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

Answer 5

Ctrl+2, L 会做你想要的。

Answer 6

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 7

我不认为我看到了Alt+Shift+L ，但这有效，如果你的右手分配是唯一的东西，你甚至不必突出它

Answer 8

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