Method Overloading (Based on Order of Arguments)

Here, we will create a class and implement method overloading by creating methods with different order of arguments to print a specified character on the console screen.

Scala code to implement method overloading based on the different order of arguments

The source code to implement method overloading based on a different order of arguments is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to implement method overloading 
// based on different order of arguments

class Calc {
  def printChar(num: Int, ch: Char) {
    var i: Int = 0;

    while (i < num) {
      printf("%c", ch);
      i = i + 1;
    }
    println();
  }
  def printChar(ch: Char, num: Int) {
    var i: Int = 0;

    while (i < num) {
      printf("%c", ch);
      i = i + 1;
    }
    println();
  }
}

object Sample {
  def main(args: Array[String]) {
    var obj = new Calc();

    obj.printChar(5, '*');
    obj.printChar('@', 4);
  }
}

Output

Explanation

In the above program, we used an object-oriented approach to create the program. And, we created an object Sample.

Here, we created a class Calc. In the Calc class, we implemented method overloading by creating two PrintChar() methods with different order of arguments. The PrintChar() method is used to print the specified character on the console screen.

In the main() function, we created an object of the Calc class and called both methods with arguments, and printed the result on the console screen.
