Control Structures: As a build-up from the previous question, consider 3 possible scenarios of input: A character, number, or word. Your program should then do the following:

• In case the input is a character it should indicate if it’s a vowel or not
• when a number is entered then it’s should check if it’s a prime
• Finally, if a word is entered the system should check if it’s a palindrome or not.

     Sample Run 1                               Sample Run 3

             Enter a character, number or word : c                  Enter a character, number or word : 7 

             Output 1 : C is not a vowel                                     Output 3 : 7 is a prime number  

Sample Run 2

              Enter a character, number or word: programming

Output 2: Programming is not a palindrome

Using the provided recording and your knowledge from programming 1. Create a program in java that takes in an input from the user and checks whether it’s a number or a word. In case a number is entered the program should print the number to the power 3 and if a word is entered your program should split that word into 2.

Write a program in Java that ask the user to enter their name, year of birth, and salary. The program must display thier name, age, and salary.

In the file RandomNumbers.java, write a class called RandomNumbers that has three integer instance variables: var1, var2, and var3. Write getter method for each variable: getVar1(), getVar2() and getVar3() and a RandomNumbers constructor that set the initial values of all the instance variables to 0. Then write the following 2 instance methods:

• setRandomValues( ) - accepts a low and high integer values as parameters, and sets var1, var2, and var3 to random numbers (generated using the Random class) within the range of the low and high input values (inclusive).

• getRandomValues( ) - prints out the 3 random numbers in the format: "Random values: var1 var2 var3"

Ex: If the input is:

15 20

the output may be:

Random values: 17 15 19

where 17, 15, 19 can be any random numbers within 15 and 20 (inclusive).

In plane geometry, the x- and y axis of a 2D Cartesian system divide it into four infinite regions called quadrants. Your task is to model each point with an x-value and y-value. Apart from the constructors, getters, and setters, implement a getQuadrant method to determine the region in which a given point falls.

    Sample Run1                                                           Sample Run2

        Enter the x and y value: 5 8                                          Enter the x and y value: 7 -3

       Output1: Point (5,8) is in Quadrant I                       Output2: Point (7,-3) is in Quadrant IV

Create a project to model students with firstname, lastname, age, gender and student number. Create two constructors, one to be used as default and another to include all attributes. Add a class attribute to keep count of all registered students. Use the class attribute to generate student numbers with the following format 22201XYZ, where XYZ is the current count provided by the class attribute. Implement the respective getters and setters for each attribute. Now given a list of student information create the respective objects and print out their details see samples below, make sure the student class has a toString method.

Sample Run1

John Doe 29 M

Kelly Daniela 40 F

Output1:

Full names : John Doe

Age : 29

Gender : M

Student Number : 22201001
