In this assignment you will create a graphical reverse polish notation calculator using a stack data structure. A reverse polish notation calculator allows you to perform chain calculations by using, a postfix operator. The assumption is that the operator serves as the delimiter and specifies the order of operations regardless of precedence. For example, 5 5+4*10/ would 5 and 5 together, multiply the result by 4 and divide that by 10 which should return 4 as a result. Please note that you must find some way of delimiting the first operand. You note I used a blank space; however, this is not the only possibility. Please use the following operators in your program:
+ Addition
- Subtraction
*multiplication
/ Division
^ Exponentiation
% modulus division
# Square root
& percentage
You must also make also sure that each operator is preceded by two operands and the operators are correct. The only exception to this is the square root operator. If this is not the case, please pop up an error message. To complete this assignment successfully, please, it must all graphical. I will accept codes only on Java 6 or Java 7 and use Stack.
