java - 如何使用IntelliJ快捷方式将Java中的Runnable更改为lambda表达式(How to change Runnable to lambda expression in Java with IntelliJ shortcut)

Question

I have the following anonymous Runnable implementation.

(我有以下匿名Runnable实现。)

Runnable cronTask = new Runnable() {
       @Override
       public void run() {
          // do something
       }
};

IntelliJ suggests that I replace it with a lambda expression.

(IntelliJ建议我将其替换为lambda表达式。)

eg:

(例如：)

Runnable cronTask = () -> {
     // multiple "do something" statements
};

When using a single statement the syntax is:

(使用单个语句时，语法为：)

Runnable cronTask = () -> doSomething();

What shortcut can I use to convert it?

(我可以使用什么快捷方式进行转换？)

Let IntelliJ do the lifting here;

(让IntelliJ在这里完成工作；)

you can invoke Alt + Enter (or Option + Return on Mac) to allow IntelliJ to replace it with a lambda expression.

(您可以调用Alt + Enter （或在Mac上为Option + Return ）以允许IntelliJ用lambda表达式替换它。)
