Scala:在一条语句中将字符串写入文件

import java.io.{File, PrintWriter}

object WriteToFile {
  def main(args: Array[String]): Unit = {
    val content = "Hello, Scala!"
    val filePath = new File("output.txt")
    val writer = new PrintWriter(filePath)
    writer.write(content)
    writer.close()
  }
}

import java.io.{File, PrintWriter}

object WriteToFile {
  def main(args: Array[String]): Unit = {
    val content = "Hello, Scala!"
    val filePath = new File("output.txt")
    if (!filePath.exists()) {
      filePath.createNewFile()
    }
    val writer = new PrintWriter(filePath)
    writer.write(content)
    writer.close()
  }
}

import java.io.{File, PrintWriter}

object WriteToFile {
  def main(args: Array[String]): Unit = {
    val content = "Hello, Scala!"
    val filePath = new File("output.txt")
    val writer = new PrintWriter(filePath)
    writer.write(content)
    writer.flush() // 确保内容被刷新到文件中
    writer.close()
  }
}
