用于循环的Python范围函数 [英] For loop - like Python range function

问题描述

 范围（4）
  

会返回

这是一个简单的方法增强的循环。在Java中这样做会很好，因为这样做会使循环变得更容易。这可能吗？

解决方案

Java 8添加了 IntStream （类似于apache的commons IntRange），所以你现在不需要外部的lib了。

  IntStream.range（0，3）.forEachOrdered（n  - > {
 //在这里工作
}）; 
  

forEach 可以代替 forEachOrdered 如果订单不重要。

I was wondering if in Java there is a function like the python range function.

range(4)

and it would return

[0,1,2,3]

This was an easy way to make for enhanced loops. It would be great to do this in Java because it would make for loops a lot easier. Is this possible?

解决方案

Java 8 has added IntStream (similar to apache commons IntRange), so you don't need external lib now.

IntStream.range(0, 3).forEachOrdered(n -> {
    //work on n here
});

forEach can be used in place of forEachOrdered too if order is not important.
