Hi,


Yes you can do this on VF page.

 

Try the below code as reference:


<apex:page controller="Calculator">
<apex:form >
<apex:inputText value="{!number1}"/>
<apex:inputText value="{!number2}"/>
<apex:inputText value="{!operator}"/>
<apex:commandButton value="ShowResult" action="{!calculation}">{!result}</apex:commandbutton>
</apex:form>
</apex:page>
//////////////// Controller /////////////////
public class Calculator
{
public integer number1{get;set;}
public integer number2{get;set;}
public string operator{get;set;}
public double result{get;set;}
public void calculation()
{
if(operator.contains('+'))
result=number1+number2;
if(operator.contains('-'))
result=number1-number2;
}
}

Hi Fanindra Mohan Choudhary,

I have tried the code written by you and it is working perfectly. I am facing issue while writing test class for the same. Would you be able to share the test class?
