Scala Programming: Get the character at the given index within the String and print the length of the string

Scala Programming String Exercise-1 with Solution

Write a Scala program to get the character at the given index within a given String. Also print the length of the string.

Sample Solution:

Scala Code:

object Scala_String {

  def main(args: Array[String]): Unit = {
    var str ="Scala Exercises!";
    println("Original String =" + str);
    // Get the character at positions 0 and 10.
    var index1 = str.charAt(0);
    var index2 = str.charAt(10);
    var index3 = str.charAt(15);

    // Print out the results
    println(s"The character at position 0 is ${index1}");
    println(s"The character at position 10 is ${index2}");
    println(s"The character at position 15 is ${index3}");
    println(s"Length of the string: ${str.length}")
  }
}

Sample Output:

Original String = Scala Exercises!
The character at position 0 is S
The character at position 10 is c
The character at position 15 is !
Length of the string: 16
