LABORATORY EXERCISE$-9$

Problem: Create the class on the UML class diagram.

$\backslash$table$[[$Calculator$],[\backslash$table$[[+$ brand: String$],[+$ digits: $10($final$)]]],[\backslash$table$[[$At add$($double double$)$ double$],[$subtract$($double$,$ double$)$ couble$],[$multiply$($double double$)$ double$],[$divide$($double$,$ double$)$ double$]]]]$

Write Calculator class according to UML Class diagram.

Create a constructor for the class.

Encapsulate brand and create getter and setter.

Place toString method in the class.

Obtain the methods as "static":

Obtain the digits property as final and $10.$

Create your application.

Inside the application call static methods of Calculator to make some calculations. $($Numbers will be user enterance$)$

If user wants to make calculations then application should continue if not it should end.

For example: To make calculation $1,$ Exit:$0$

If $1$ then

Choose operation $1-$Add, $2-$Multiply, $3-$Subtract, $4-$Division

If $1$ then

Enter first number: $10$

Enter second number: $20$

The result is: $30$

When user wants to exit then show brand and digits properties.

For example: The program has been ended, brand$=$Samsung, digits$=10$
