def processWindowsPath(p: String): String {
"file:///" + p.replaceAll("\", "/")
}
}
Compiler gives an error:
编译器报错：

FileOperations.scala:6: error: illegal start of declaration

为什么？怎么修？
回答by Jon McAuliffe
You're missing an = from the processWindowPath method declaration.
您缺少 processWindowPath 方法声明中的 = 。
package FileOperations
import java.net.URL
object FileOperations {
def processWindowsPath(p: String): String = {
"file:///" + p.replaceAll("\", "/")
}
}

object FileOperations {
def processWindowsPath(p: String): String = {
"file:///" + p.replaceAll("\", "/")
}
}
There is a missing =. Methods in Scala are defined this way:
有一个缺失=。Scala 中的方法是这样定义的：
def methodName(arg1: Type1, arg2: Type2): ReturnType = // Method body
