Simple Scala program not executing on command prompt [closed]

Question

This is some of the strange issue, the program is only printing hello scala, but it seems that I am getting syntax weird error. Please correct me if I miss anything

Program

 object hello{
     def main(args:Array[String]){
            println("Hello Scala")
        }
    }

Error:- '=' expected, but '{' found

Answer 1

As the error message suggests, you need a = before the {:

def main(args: Array[String]) = {
  println("Hello Scala")
}

The syntax you used was originally supported so you might see it in some example code. But it was deprecated in later versions and is now no longer allowed.
