我正在学习Scala并在编写一些程序时。我正在关注
>错误:无法找到或加载主类动物即使我删除了类,我也收到此错误或重命名该课程。 我在 src-> main-> scala->动物(包) - >动物(类)。
我试图在Google和这个网站上搜索解决方案,但这对我没有帮助。请让我知道我错过了什么。我在 Intellij 上运行此程序。
我也为其他程序收到此错误。
package Animal class Animal { def a:Int = 10 println(a)}解决方案
也许您以前编写了一个 main 方法所在的应用程序 Animal 对象。删除指向此类的运行配置,或者通过使对象使用<$来使 Animal 应用程序c $ c> main 方法,例如:
package Animal 对象动物{ def a:Int = 10 def main(args:Array [String]):单位= println(a) }您还可以使用 App trait并跳过 main 方法的定义,而不是按如下方式编辑代码。
package Animal object Animal extends App { def a:Int = 10 println(a) }
I am learning Scala and while writing some programs. I am getting following
> error:could not find or load main class AnimalI am getting this error even if I delete the class or rename the class. I am creating this program inside src->main->scala->Animal(package)->Animal(class).
I tried to search for solutions on Google and on this site but that did not help me. Please let me know what I am missing. I am running this program on Intellij.
I am getting this error for other programs as well.
package Animal class Animal { def a:Int = 10 println(a) }解决方案
Perhaps you have previously written an application whose main method was in the Animal object. Either delete the run configuration that points to this class or make Animal an application by making it an object with a main method, e.g.:
package Animal object Animal { def a: Int = 10 def main(args: Array[String]): Unit = println(a) }You can also use the App trait and skip the definition of the main method, than you could edit your code as follows.
package Animal object Animal extends App { def a: Int = 10 println(a) }
