You should read the instructions in the file. Q1) Explain two roles of the java virtual machine as part of java runtime environment?
Describe the intermediate representation of a Java program that allows a JVM to translate a program into machine-level assembly instructions. Q2)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. (include screenshots of all program execution steps) . IMPRTANT NOTE question 2): Submission from the Replit program. The important thing is that I write my first name, Razan, and my last name, Khaled.
Also you can change the category name to any name and the scanner name to any name?
Q3) 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.
Use parentheses to rewrite the java representation. .
Q4)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: IMPORTANT NOTE You need to write my name, Rzan Khaled, and in the number, write the number 7. Second note, you must change string, such as typing any name. Important notes:
Avoid plagiarism, the work should be in your own words, copying from students or other resources without proper referencing will result in ZERO marks. No exceptions.
