遍历方法参数 [英] Iterating through method parameters

问题描述

这是一个简单的问题，也许是个琐碎的问题:在Java中，我如何遍历传递给我正在工作的方法的参数?

It's a simple and maybe trivial question: in Java how can I iterate through the parameters passed to the method where I'm working?

我需要它来trim()所有都是字符串的

I need it to trim() all of them that are strings.

编辑

更准确地说，可以使用以下示例(用伪代码编写，以反映我希望其工作的方式):

To be more precise an example of use can be this (written in a pseudo-code reflecting how I wish it to work):

public void methodName(String arg1, int arg2, int arg3, String arg4, double arg5)
    for(Object obj : getThisMethod().getParameters() )
        System.out.println(obj.getName() + " = " + obj.toString())

重点是getThisMethod().getParameters().我必须在那个地方写些什么?

The point is that getThisMethod().getParameters(). What must I write in that place?

推荐答案

单个参数不可迭代；您将需要一个集合.

Individual parameters aren't iterable; you'd need a collection for that.

如果它们是单独的弦弦，则只需要铲铲即可.

You'll just have to get a shovel if they're individual Strings.

如果您有太多令人讨厌的String参数，则可能需要重新考虑您的方法.要么将所有这些参数都封装到一个对象中(因为它们是相关的)，要么该方法试图做太多事情.这说明我缺乏凝聚力.

If you have so many String parameters that this is oppressive, perhaps your method needs to be re-thought. Either all those parameters should be encapsulated into an object, because they're related, or that method is trying to do too much. It speaks to a lack of cohesion to me.
