## Calculator program in Scala

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:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 |
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
