Scala:在一个语句中将字符串写入文件 [英] Scala: write string to file in one statement

问题描述

在Scala中读取文件，有

For reading files in Scala, there is

Source.fromFile("file.txt").mkString

是否有等效且简洁的方法将字符串写入文件?

Is there an equivalent and concise way to write a string to file?

大多数语言都支持类似的东西.我最喜欢的是 Groovy:

Most languages support something like that. My favorite is Groovy:

def f = new File("file.txt")
// Read
def s = f.text
// Write
f.text = "file contents"

我想将代码用于从一行到一小页代码的程序.必须使用自己的库在这里没有意义.我希望有一种现代语言能让我方便地向文件中写入内容.

I'd like to use the code for programs ranging from a single line to a short page of code. Having to use your own library doesn't make sense here. I expect a modern language to let me write something to a file conveniently.

有类似的帖子，但它们没有回答我的确切问题，或者专注于较旧的 Scala 版本.

There are posts similar to this, but they don't answer my exact question or are focused on older Scala versions.

例如:

• 在 Scala 中读取整个文件?
• 如何在 Scala 中写入文件?

推荐答案

简洁的一行:

import java.io.PrintWriter
new PrintWriter("filename") { write("file contents"); close }
