Scala, importing class
提问by matiit
I have two files:
我有两个文件：
logic.scala and main.scala
logic.scala 和 main.scala
logic.scala contains one class and main.scala have one class with method main (to run it). And I want to import a class from logic.scala and use this class to create object(s) and work with them.
How to import and compile it in proper way?
logic.scala 包含一个类，而 main.scala 有一个带有方法 main（运行它）的类。我想从 logic.scala 导入一个类并使用这个类来创建对象并使用它们。
如何以正确的方式导入和编译它？

logic.scalacode
logic.scala代码
package logic class Logic{ def hello = "hello" }
package logic class Logic{ def hello = "hello" }
main.scalacode
main.scala代码
package runtime import logic.Logic // import object Main extends Application{ println(new Logic hello) // instantiation and invocation }
package runtime import logic.Logic // import object Main extends Application{ println(new Logic hello) // instantiation and invocation }
- compile the files with
scalac
- 编译文件
scalac
scalac *.scala
scalac *.scala
- run your application with
scala
- 运行您的应用程序
scala
scala -cp . runtime.Main
scala -cp . runtime.Main
