Scala – Creating a Private Class

Here, we will create a private class. The private class cannot be accessed in the different source file.

Scala code to create a private class

The source code to create a private class is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to create a private class

private class Demo {
  // Default access specifier is public.
  var num: Int = 10;
  def printNum() {
    printf("Num: %d\n", num);
  }
}

object Sample {
  def main(args: Array[String]) {
    var obj = new Demo();

    obj.printNum();
  }
}

Output

Num: 10

Explanation

Here, we used an object-oriented approach to create the program. And, we created an object Sample.

Here, we created a class private Demo. The Demo class contains a public member num, which is initialized with 10. And, we created a printNum() method to print the value of num on the console screen. The private class cannot be accessed in the different source code file.

Then we defined the main() function. The main() function is the entry point for the program.

In the main() function, we created an object of the Demo class and called printNum() method using the created object and print the value of private member num on the console screen.
