Industrial Training Day 3 and Day 4

Day 3 and Day 4 : On 17^th May, 2019 we have designed a Calculator in Java and on 18^th May,2019 we have implemented complete functionalities of a Calculator. In this calculator we have performed many operations such as :

1)     If user try to divide by zero then it will give proper message “Cannot be divide by Zero”

                            

2)     If the user directly clicks on the operation button or equals-to button without giving any one of  the value then ,it will give proper message “Empty String”.

     

        3) Once the Clear button click then it will place  null in previous value .
