Calculator application.

This is the console calculator application to perform simple mathematical operations, such as :

• Addition (+)
• Subtraction (-)
• Multiplication (*)
• Division (/)
• Division with remainder (%)

Also the validation of user input is implemented. There is class Validation.java with such methods, as :

• public Boolean isNumberCheck(String value) - checks whether the entered character is a number
• public Boolean isMathOperationCheck(String operator) - checks whether the entered character is a valid mathematical operation

Limitations

You can execute only one operation at time.
