Here, we will create a string using the StringBuilder class and then we will insert a substring into a substring using the insert() method. Here we need to pass an index to insert substring in the insert() method.

Program/Source Code:

The source code to insert a substring into the StringBuilder string 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
// StringBuilder string

object Sample {
  def main(args: Array[String]) {
    val str = new StringBuilder("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 StringBuilder class, which is initialized with "This india". Then we inserted a substring into the string, based on the given index into the insert() method. After that, we printed the result on the console screen.
