 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.

Sample Run 1

Enter a number or word: 7

Output 1:

7 to the power 3= 343

Sample Run 2

Enter a number or word: NAMIBIA

Output 2:

The word split in half is : NAMI and BIA 

PROGRAM 3 – Times tables

You must write a small application in JAVA that will read in a positive integer and then display the times tables for that number, from 1 to 12.

Your program must

1. Read in the integer as input.

2. Calculate and display the complete times tables up to 12 for that integer.

3. If a zero or any number less is entered, an error message must be displayed and the user must be allowed to input another value.

PROGRAM 2 – Maths Calculator

Write a small application in JAVA that reads in two integers, and then asks the user to type in a character to indicate what calculation must be done with the two numbers, viz:

A to add

S to subtract

M to multiply

D to divide

Display the result of the calculation.

The output of sample runs of the program is given below (the text in bold was typed by the user).

Please use the SAME wording/messages/labels as shown.

Sample execution run 1 Sample execution run 2

Enter the first number: 27

Enter the second number: 9

What would you like to do?

A to add

S to subtract

M to multiply

D to divide

Enter choice: s

27 minus 9 is 18.

Enter the first number: 15

Enter the second number: 0

What would you like to do?

A to add

S to subtract

M to multiply

D to divide

Enter choice: D

**Error** Cannot divide by zero.

PROGRAM 1 – Shopper Calculator

You must write a small application in JAVA that can assist a shopper by calculating the total price of the items that he or she wants to buy and displaying a tillslip-like list of the products, their prices and the total due.

Your program must

1. Read the name and price of five items as input.

2. Calculate the total price for the items.

3. Display all the item names and prices.

4. Display the total due for all items.

Design a Car model class under package packages with the following attributes:

Member Field Name

licenceNumber

Type

String

String

Double

Model

currentMileage engine Size

Integer

Mark all the attributes as private & Create default & parameterized constructors

Design another class as Main under package packages, where you need to implement logic as follows

Declare an array as Car with size N where N is to be accepted from user Take N Car's information from user and store them in specified array Call sortCarlist method from Main class to get all cars information sorted based on Model name and display then within Main class after returning back

from the specified method From Main class car array need to pass within sortCarLast method which return sorted car array and then display all car information on console.

Design sortCarlist method in Car clast, as follows: will take a car array and retam car array

it will sort array based on model value given in each car as its information
