Error while printing hello world


Hello … I am a beginner in Scala and I apologize for the question. I created a class to print “Hello World” and gave an error that I can not solve. can anybody help me?

my code:

object Teste {
def main(args: Array[String]){
print(“Hello World”)

the error:

Exception in thread “main” java.lang.NoSuchMethodError:;)V
at org.jetbrains.plugins.scala.compiler.rt.ConsoleRunner.main(

Process finished with exit code 1


Looks like there is something wrong with your IntelliJ Scala plugin.


I discovered … it lacked the “extends App” … it worked now … thank you very much

my new code:

object Teste extends App{
println(“Hello World”)


Hi, I would recommend not using extends App, it will go away in future Scala. Use a main method instead as you were before:

object Test {
  def main(args: Array[String]): Unit = println("Hello, World!")


ok…very thanks…
