Scala – Length of a String

Here, we will create a string and then find the length of the string using the length() method and print the result on the console screen.

Scala code to find the length of the string

The source code to find the length of the string is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to find the length of
// the string

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

    len = str.length;

    printf("length of the string is: %d\n", len);
  }
}

Output

length of the string is: 11

Explanation

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 find the length of the string using the length() method and assigned it to the len variable. After that, we printed the length of the string on the console screen.
