Scala program to demonstrate the subSequence() method

Program/Source Code:

The source code to demonstrate the subSequence() method is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to demonstrate
// the subSequence() method

object Sample {
  def main(args: Array[String]) {
    var str: String = "Hello World";

    var res = str.subSequence(1, 4);

    printf("Sub sequence is: %s\n", res);
  }
}

Output:

Sub sequence is: ell

In the above program, we used an object-oriented approach to create the program. And, we created an object Sample. Here, we defined main() function. The main() function is the entry point for the program.

In the main() function, we created a string variable str initialized with "Hello World". Then we extracted the subsequence from the string using the subsequence() method based on start and end index and assigned the result into res variable. After that, we printed the result on the console screen.
