Chapter 5, Problem 5E
Consider a Java class that you could use to get an acceptable integer value from the user. An object of this class will have the attributes
- Minimum accepted value
- Maximum accepted value
- Prompt string
and the following method:
- getValue displays the prompt and reads a value using the class Scanner. If the value read is not within the allowed range, the method should display an error message and ask the user for a new value, repeating these actions until an acceptable value is entered. The method then returns the value read.
- a. Write preconditions and postconditions for the method getValue.
- b. Implement the class in Java.
- c. Write some Java statements that test the class.

Consider a Java class that you could use to get an acceptable integer value from the user. An object of this class will have the attributes:
Minimum accepted value
Maximum accepted value
• Prompt String and the following method:
getValue() displays the prompt and reads a value from the user. If the value read is not within the allowed range, the method should display an error message and ask the user for a new value, repeating these actions until an acceptable value is entered. The method then returns the value read.
** in JAVA **
Write a Java program called ThreeWords that prompts (asks) the userto enter three words, separated by a space, on the same line and readin using the .nextLine( ) method of the Scanner class. You may NOTuse the .next( ) method of the Scanner class in this Task. Using the .next( ) method of the Scanner class will result in this Task being awarded 0, regardless of correct execution.(You may assume that the user always enters 3 words, each word separated by a single space.)Once the user has entered the three words, the program displays to the screen the longest word, that is, the word with the most characters. In the event of one or more of the words having the same number of characters, the program may decide which word it displays to the screen.

- 4. Write a java program that will check the validity of a password:a. Prompt the user to enter a password (a string, use Scanner class to read the password)b. Check the validity of the password by calling a method, named passValidity()c. Return an appropriate message (i.e. password is valid or invalid) to the main() method. The main() method will print the message.The passValidity() method will:a. take the password as the input parameter,b. check the validity as per the following rule:• the password string must have at least eight characters • the password must have at least one alphabet • the password must contain at least one digit• the password must contain at least one special character from @, #, $, and &c. return an appropriate message to the main() method.Sample output (assuming the input is ab459#de0):The password is validSample output (assuming the input is abcd#de&ui):The password is invalidarrow_forwardConsider a class that keeps track of the sales of an item. An object of this class will have the attributes Number sold Total sales Total discounts Cost per item Bulk quantity Bulk discount percentage and the following methods: registerSale(n) records the sale of n items. If n is larger than the bulkquantity, the cost per item will be reduced by the bulk discount. displaySales displays the number sold, the total sales, and total discount. Implement the class in Java. Write some Java statements that test the class.arrow_forwardIn java, create a program that gathers user input and prints a paystub. This assignment requires one class per .java file, total of three classes. The first one is employee.java which gathers the user's id (fixed value), first name, last name, address, city, zip, phone, email, and hourly rate. The second one is payperiod.java, which gathers the user's hours worked (taking overtime into account), start date (fixed), end date (fixed), and paystub id (fixed). The third one is payrollmanager.java, which calculates and displays the data gathered from the first two. This class/file should also use methods such as: doubleCalculateGrossPay(Employee, PayPeriod), double CalculateRegularPay(Employee, PayPeriod), double CalculateOvertimePay(Employee, PayPeriod), and void PrintPaystub(Employee, PayPeriod).arrow_forward
- Java program requirements:- a PesoCurrency class with an amount attribute.- Define an overloaded convertTo method that will convert amount attribute to dollars and euros.- Conversion: 1 dollar = 50 pesos while 10 dollars = 2 euros.- Implement the class to ask the user an amount in peso to convert and will display the dollar and euro equivalent of the inputted peso amount.arrow_forward2. Write a java program which will input an integer value from the user (Use Scanner class). Your program will have mathOper() method in addition to the main() method.The main() method will be responsible for:a. extracting the 1's digit (ones), the 10's digit (tens), and any digits larger than the 10's digit. For instance, if the input is 3562, the 1's digit would be 2, the 10's digit would be 6, and the remaining digits would be 35.b. call the mathOper() method with these 3 values,c. print the results to the screen.The mathOper() method will make the following calculations:a. Multiply the 1's digit by 7, subtract the result by 2 and then divide that by 5.b. Add 3.5 to the 10's digit, multiply the result by 4.3 and then divide that by 2.c. Subtract 5 from the remaining digits, multiply the result by 3, find the remainder after dividing that by 7, and then add 6 to the remainder value.d. Add the 3 values obtained from ‘a’, ‘b’, and ‘c’ operations.e. Return the final value.Sample output…arrow_forwardImplement the below pseudo-code in a Java program using a while loop and aswitch-case statement. The program should be well structured, and the taskperformed under each option (at least options 'b' to 'e') should be implementedas a separate method.NOTE: The Scanner class does not have a method to input a character. Inorder to read a character from the keyboard, use one of the following methods(after declaring the Scanner object):static Scanner kb = new Scanner(System.in);1. char ch = kb.nextLine().charAt(0); OR2. char ch = kb.nextLine().toLowerCase().charAt(0);where kb is a Scanner class object.The second method above also converts the input to lowercase, which is oftenuseful. Though these methods allow the user to input more than one characteron the input line, the rest of the line (after capturing the first character withcharAt(0)) is discarded.If you also want to ignore the leading spaces before the first character thenuse:1. char ch = kb.nextLine().trim().charAt(0); OR2. char ch =…arrow_forward

A Baby has a name of type String and an age of type integer.Supply two constructors: one will be the default constructor, that just setsdefault values for the name and age; the second constructor will take twoparameters, a string to set the name and an integer to set the age. Also, supply methods for setting the name, setting the age, getting the name and getting the age.The class should not contain I/O methods; input of values to the instancevariables must be done with a set method or constructor, output of values from the instance variables must be done with get methods. The set method for the name instance variable should ensure that the input is not empty or contain whitespaces (otherwise set a default value). The set method for the age instance variable should validate the input to be between 1 and 4 inclusive(otherwise set a default value).Give Java code for an equals method for the Baby class.
