Chapter 7, Problem 4PE
Program Plan Intro
Program to display valid and invalid password
Program plan:
Filename: “ValidatePassword.java”
- Define the “ValidatePassword” class
- Declare the required variables and set the values.
- Create an object for scanner class.
- Prompt the user to enter the password.
- Read the length of the string and store it in a variable.
- Using, if…else condition check whether the string contains two uppercase, 3 lowercase and one digit.
- If the condition is satisfied, print the string as valid password, else print as invalid password.

Big State University
The Big State University course catalog reads as follows: "To enroll in MIS 260, which is an advanced
course, a student must complete two prerequisites: MIS 120 and MIS 222. A student who completes
either one of these prerequisites and obtains the instructor's permission, however, will be allowed to
take MIS 260."
Tasks
1. Create a decision table that describes the Big State University course catalog regarding eligibility for
MIS 260. Show all possible rules.
2. Simplify the table you just created. Describe the results.
3. Draw a simplified decision tree to represent the Big State University catalog. Describe the results.
4. Why might you use a decision tree rather than a decision table?

Additional resources in this week’s learning module will provide further perspectives on the impact of wind energy on different stakeholders. Students should refer to the syllabus for specific guidelines regarding length, format, and content requirements. Reflection Questions to Consider: What are the key institutional challenges in implementing offshore wind energy in the North Sea? How do formal and informal social rules shape the use of this shared space? What conflicts arise between different stakeholders (e.g., fishermen, naval transport, military, and wind energy developers)? How can policymakers balance economic, environmental, and social considerations when allocating space for wind energy?…arrow_forwardAlphabetic Telephone Number TranslatorMany companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD, the application should display 555-438-3663.arrow_forward
