Learning Outcome(s): CLO4 Develop a program based on specification using programming language elements including syntax, data types, conditional statement, control structures, procedures, arrays, objects and classes. |
Question Two
Create a Java program that does the following:
- Prompt the user for an input.
- Enter your first and last names as the input.
- Read the entered input into two variables (one variable stores the first name while the other stores the last name).
- Using the printf function, print the variables in upper-case characters and each in a separate line.
- Use parentheses to rewrite the java representation.

Question Three
The cubic polynomial function of the third degree can be represented as:
y = ax3 + bx2 + cx + d
- Write the correct Java representation of the function without using parentheses using the Rules of Operator Precedence.
- Evaluate the java representation of the function and find the value of y when,
x=3, a=1, b=2, c=3, d=4
Make sure that you show all the steps in detail.

Question Four
Write a java program that asks the user to enter his/her name. Print a welcome message and ask the user to enter a number. Then, tell the user the type of the number (positive, negative, or zero).
Note: you must take a screenshot of the output that shows your name in the run.
Sample of the run:
