Your first Scala program

When first learning something, we all want to see how it works. So, I’m going to create a quick program and run it so you can have your first bite of Scala.

In IntelliJ IDEA, right-click on the folder you want to create the class and select create new Scala class. In the next windows, make sure you select Object instead of Class

If you have a background in Java, you are familiar with public static void main. The following code is the equivalent of that:

package com.datmt.scala

object FirstProgram {
  def main(args: Array[String]): Unit = {
   print("Hello")
  }
}

When you run it, the console displays “Hello” as expected.

That’s your first program in Scala. It’s simple, isn’t it?
