Scala program to replace the character with another character in the string

Program/Source Code:

The source code to replace the character with another character in the string is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to replace the character
// by another character in string

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

    res = str.replace('a', 'A');
    printf("String after replacing character is: %s\n", res);
  }
}

Output:

String after replacing character is: BAnAnA

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 with the initial value "Banana". Then we replace the character 'a' with the character 'A' in string str and assigned the result into the res variable. After that, we printed the value of the res variable on the console screen.
