Groovy 写入文件(换行) [英] Groovy write to file (newline)

问题描述

我创建了一个简单的将文本写入文件的小函数，但是我在将每条信息写入新行时遇到了问题.有人可以解释为什么它把所有东西都放在同一条线上吗?

I created a small function that simply writes text to a file, but I am having issues making it write each piece of information to a new line. Can someone explain why it puts everything on the same line?

这是我的功能:

public void writeToFile(def directory, def fileName, def extension, def infoList) {
    File file = new File("$directory/$fileName$extension")

    infoList.each {
        file << ("${it}
")
    }
}

我用来测试它的简单代码是这样的:

The simple code I'm testing it with is something like this:

def directory = 'C:/'
def folderName = 'testFolder'
def c

def txtFileInfo = []

String a = "Today is a new day"
String b = "Tomorrow is the future"
String d = "Yesterday is the past"

txtFileInfo << a
txtFileInfo << b
txtFileInfo << d

c = createFolder(directory, folderName) //this simply creates a folder to drop the txt file in

writeToFile(c, "garbage", ".txt", txtFileInfo)

上面在该文件夹中创建了一个文本文件，文本文件的内容如下所示:

The above creates a text file in that folder and the contents of the text file look like this:

Today is a new dayTomorrow is the futureYesterday is the past

如您所见，文本全部聚集在一起，而不是在每个文本的新行上分开.我认为这与我如何将其添加到我的列表中有关?

As you can see, the text is all bunched together instead of separated on a new line per text. I assume it has something to do with how I am adding it into my list?

推荐答案

在我看来，就像您在 Windows 中工作一样，在这种情况下，换行符不是简单的 而是

It looks to me, like you're working in windows in which case a new line character in not simply but rather

例如，您始终可以通过 System.getProperty("line.separator") 获取正确的换行符.

You can always get the correct new line character through System.getProperty("line.separator") for example.
