Java中的闭包7 [英] Closures in Java 7

问题描述

我听说关闭可以引入下一个Java标准，计划在明年夏天发布。

这种语法是什么样子？

通用是在java 5.这是真的吗？优点和缺点？

（现在我们绝对知道，closures不会被包含在下一个Java版本中）

解决方案

请查看 http：/ /www.javac.info/ 。

看起来像是这样：

  boolean even = {int x => x％2 == 0} .invoke（15）; 
  

其中 {int x = x％2 == 0} 位是闭包。

I have heard that closures could be introduced in the next Java standard that is scheduled to be released somewhere around next summer.

What would this syntax look like?

I read somewhere that introducing closures in java is a bigger change than generic was in java 5. Is this true? pros and cons?

(By now we definitely know that closures not will be included in the next Java release)

解决方案

Have a look at http://www.javac.info/ .

It seems like this is how it would look:

boolean even = { int x => x % 2 == 0 }.invoke(15);

where the { int x => x % 2 == 0 } bit is the closure.
