Scala program to get characters from the string

Program/Source Code:

The source code to get characters from the string is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to get characters from string.

object Sample {
  def main(args: Array[String]) {
    var str = "Hello World";
    var ch: Char = 0;
    var i: Int = 0;

    println("String is: ");
    while (i < str.length) {
      ch = str.charAt(i);
      printf("%c ", ch);
      i = i + 1;
    }
    println();
  }
}

Output:

String is: 
H e l l o   W o r l d

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 got the characters from the string one by one using charAt() and printed the result on the console screen.
