为什么在Scala中非法开始声明？

Question

对于以下代码:

package FileOperations
import java.net.URL

object FileOperations {
    def processWindowsPath(p: String): String {
        "file:///" + p.replaceAll("\\", "/")
    }
}

编译器给出错误:

> scalac FileOperations.scala
FileOperations.scala:6: error: illegal start of declaration
        "file:///" + p.replaceAll("\\", "/")

为什么？怎么修？

Answer 1

您从processWindowPath方法声明中缺少一个=.

package FileOperations
import java.net.URL

object FileOperations {
    def processWindowsPath(p: String): String = {
        "file:///" + p.replaceAll("\\", "/")
    }
}

Answer 2

object FileOperations {
  def processWindowsPath(p: String): String  = {
    "file:///" + p.replaceAll("\\", "/")
  }
}

有一个失踪=.Scala中的方法以这种方式定义:

def methodName(arg1: Type1, arg2: Type2): ReturnType = // Method body
