The first class represents a student and must be named using your first and last name.

Question One

Write a complete Java program that performs the following tasks:

1. Ask the user to enter his/her full name and print a welcome message using the user’s name.
2. Ask the user to enter any city.
3. Ask the user to enter the weather temperature.
4. Ask the user to enter 1 or 2 to choose the type of conversion.
5. Write two methods that should take a city and a temperature as arguments, and print the Celsius or Fahrenheit equivalent, using the following calculations:

Celsius = 5.0 ÷ 9.0 × (Fahrenheit – 32)

Fahrenheit = 9.0 ÷ 5.0 × Celsius + 32

Each method will be called based on the user choice. For example,

• if the user enters 1, the method that calculates and prints Celsius is invoked
• if the user enters 2, the method that calculates and prints Fahrenheit is invoked.

Note:

• The class name of your Java program must be your first name.
• Your answer should have the code as text as well as the screenshot of the program output (using your own name) as a part of your answer. Otherwise, zero marks will be awarded.

Question Two

Write a complete Java program that performs the following tasks:

1. Create and initialize an array named studID with 9 elements. The array must be initialized with your student id. For example, if your student ID is 123456749, you need to take each single digit as the elements of your array.
2. Print the elements of the array using enhanced for loop.
3. Asks the user to give a number between 1 and 9 and save it in a variable num.
4. In the array studID, find and print the following:

• Count the numbers divisible by num
• Number of even numbers that is less than num
• Number of odd numbers that is less than num
• The sum of all numbers that are divisible by 3 or by 4.

Note:

• The class name of your Java program must be your first name.
• Your answer should have the code as text as well as the screenshot of the program output (using your own student ID) as a part of your answer. Otherwise, zero marks will be awarded.

Question Three

Write a complete Java program as follow:

1. Create two java classes:
   1. The first class represents a student and must be named using your first and last name.
   2. The second class must be named as “Main” with the main method.
2. Perform the following in the first class:
   1. Create three private instance variables to store first name, last name and GPA. Do not assign any values to the variables in this step!
   2. Create a constructer without parameters to initialize all the instance variables to default values (0 for numbers and “” for a string).
   3. Create a constructor that can take the first and last name as parameters. Assign the parameters’ values to the two instance variables you created earlier (first and last name).
   4. Create a getName() method to return the first and last name. You must return the first and last name in a single string using a plus sign. You must have a space between the first name and last name.
   5. Create setGPA() and getGPA() methods to store and return your GPA, respectively.
3. Perform the following in the main class:
   1. Create a new object of your first class and pass your first and last name as two parameters.
   2. Call the getName() method and store the result in a string variable called myFullName.
   3. Print your full name using the string variable myFullName.
   4. Set your GPA using the setGPA()
   5. Print your GPA using the getGPA()

Note:

• Your answer should have the code as text as well as the screenshot of the program output (using your own name) as a part of your answer. Otherwise, zero marks will be awarded.
