Calculator – Clear ur Doubt

Hey there! Welcome to ClearUrDoubt.com. In this post, we will look at a Scala program to implement a Calculator operations. Let’s look at the program:

package com.clearurdoubt

class Calculator 
{
  def +(a: Int, b: Int): Int = a+b
  
  def -(a: Int, b: Int): Int = a-b
  
  def *(a: Int, b: Int): Long = a*b
  
  def /(a: Int, b: Int): Int = 
  {
    require(b != 0, "denominator can not be 0")    
    a/b
  }
}

object Calendar
{
  def main(args: Array[String]) =
  {
    val calc = new Calculator()
    
    println("Addition: " + calc.+(10, 2))
    println("Subtraction: " + calc.-(10, 2))
    println("Multiplication: " + calc.*(10, 2))
    println("Division: " + calc./(10, 2))

    //println("Division: " + calc./(10, 0))
  }
}

package com.clearurdoubt

class Calculator

{

def +(a: Int, b: Int): Int = a+b

def -(a: Int, b: Int): Int = a-b

def *(a: Int, b: Int): Long = a*b

def /(a: Int, b: Int): Int =

{

require(b != 0, "denominator can not be 0")

a/b

}

object Calendar

{

def main(args: Array[String]) =

{

val calc = new Calculator()

println("Addition: " + calc.+(10, 2))

println("Subtraction: " + calc.-(10, 2))

println("Multiplication: " + calc.*(10, 2))

println("Division: " + calc./(10, 2))

//println("Division: " + calc./(10, 0))

}

Output: We have created a Calculator class with 4 typical calculator methods +(addition), -(subtraction), *(multiplication) Read more
