Question
By Using Java Language
Create a post fix calculator (34+ vs 3+4) using a Stack. The calculator should be able to handle all basic mathematical operations (+,-,/,*) You will not use parenthesis, but the program would work like a traditional infix notation -> see example below.
Post fix example 1 2 + 3 * 6 + 2 3 + /
This means "take 1 and 2, add them, take 3 and multiply, take 6 and add, take 2 and 3, add them, and divide". In contrast, the equivalent expression in Infix(((1 + 2) * 3) + 6) / (2 + 3)
This may seem more familiar, but note the need for parentheses to control the order of evaluation.
The user should be able to enter each number/operator into the Stack one at a time and type = (equals) to see their result:
3 (return/enter)
4 (return/enter)
+ (return/enter)
= (return/enter)
Your total is: 7
