Description

Create an appropriate Java Postfix calculator class (Carrano & Henry, 2015, p. 177). Your program should accept at least five elements (data1, data2, data3, data4, data5) and perform an appropriate postfix operation given the following scenarios:data1 data + data3 * data4 –data1 data * data3 * data1 – / data4 data5* +Use the following values for each input:data1 = 1;data2 = 2;data3 = 4data4 = 5data5 = 3Ensure that your program has the required class and a test class. Submit Exercise 8 and screenshots of your program’s execution and output compiled into a single document. Also attach all appropriate source code in a zip file.Carrano, F. M., & Henry, T. (2015).

7. Using the algorithm convertToPostfix, given in Segment 5.16, convert each of the following infix expres-

sions to postfix expressions:

a. a*b/(c-d)

b. (a – b* c)/(d* e* f+g)

c. a/b* (c + (d – e))

d. (a^b* -d)^e+f^g^h

8. Using the algorithm evaluatePostfix, given in Segment 5.18, evaluate each of the following postfix expres-

sions. Assume that a = 2, b = 3, c = 4, d = 5, and e = 6.

a. a b + c d-

b. ab*ca- / de* +

c. a c-b1d +

9. What infix expressions are represented by the postfix expressions given in the previous exercise?

10. Show the contents of the two stacks as you trace the algorithm evaluate Infix, given in Segment 5.21, to

evaluate each of the following infix expressions. Assume that a = 2, b = 3, c = 4, d = 5, e = 6, and f = 7.

a. (a + b)/(c-d) – 5

b. (d * f+1) * e/(

ab-b* C+1) – 72

с. (алс-f) ла-алbла

11. A palindrome is a string of characters (a word, phrase, or sentence) that is the same regardless of whether

you read it forward or backward assuming that you ignore spaces, punctuation, and case. For example,

Race car is a palindrome. So is A man, a plan, a canal: Panama. Describe how you could use a stack to test

whether a string is a palindrome.
