在 IntelliJ 中，是否有一种快捷方式可以获取我已经输入的变量作为我想要输入的方法中的参数？

Question

Suppose I have this code:

var x = 2;
var y = x;

Then I realize that I actually wanted this:

var y = someMethod(x);

To accomplish this, first I need to position the cursor to the left of "x", then type "someMethod(", then move my cursor to the right, and then add the final ")".

What I'd love is to have a way to, say, highlight "x", and have it automatically get inserted as a parameter to whatever I start typing.

Is there something for this in IntelliJ?

Answer 1

Put the cursor at the left of x , start typing the method name and wait for the autocompletion sugestions to appear (if they don't press CTRL+Space), find your method in the list, select it with keyboard arrows, and press ENTER. IDEA will automatically use x as the parameter of the mthod.

Answer 2

Try using Statement Completion :

• Point the cursor before x
• Start typing the method name
• Select the needed variant and press Ctrl + Shift + Enter
