Dual Keypad Calculator





This is a new style dual keypad calculator, the reason for which is that developing a typical single keypad calculator required the knowledge of data structures in java which I didn't had at the time but it was developed with object oriented programming in java.


Working


First operand is entered through one keypad and the second operand is entered through the other while the operator is selected from the provided radio buttons. Pressing the "=" button calculates the result which can be used as a first or second operand for further calculations by pressing the transfer1 or transfer2 buttons respectively. If the automatic checkbox is checked, the result from the previous calculation automatically goes to the respective operand for next calculation.
