Program/Source Code:

The source code to insert a substring into a string created using StringBuffer is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to insert a substring
// into StringBuffer string

object Sample {
  def main(args: Array[String]) {
    val str = new StringBuffer("This india");

    printf("String is: '%s'\n", str);

    //insert a substring into string.
    str.insert(4, " is");

    printf("String is: '%s'\n", str);
  }
}

Output:

String is: 'This india'
String is: 'This is india'

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 an immutable string str using the StringBuffer class. Then we inserted substring " is" from string using insert() method into string str and printed the result on the console screen.
