Write a method that accepts a string as an argument and checks it for proper capitalization and punctuation. The method should determine if the string begins with an uppercase letter and ends with a punctuation mark. The method should return true if the string meets the criteria; otherwise it should return false.
Where is the result kept if a TryParse method successfully translates the string argument?
In this assignment you will use the MyString class that you wrote earlier in this course.
A palindrome is a string that reads the same forward and backward. Write a program that reads in any number of MyStrings from the user and determines if each MyString is a palindrome. The user will terminate each MyString by pressing the return (or enter) button. The user will indicate that there are no more MyStrings by entering "quit".
To do this you must write a recursive function named isAPalindrome that takes a single MyString argument and two arguments that are bounds on MyString indices. The function must examine the part of the argument between the two bounds (including the bounds) and return true if this part of the argument is a palindrome, false if it is not a palindrome. The function must be recursive and must not call any other functions except ispunct(), isspace(), and toupper() (described below).
Do not make any changes to the MyString class (except, if necessary, to correct errors…

In previous chapters, you have developed a class that holds catering event information and an application that tests the methods using four objects of the class. Now modify the Event and EventDemo classes as follows: Modify the method that sets the event number in the Event class so that if the argument passed to the method is not a four-character String that starts with a letter followed by three digits, then the event number is forced to A000. If the initial letter in the event number is not uppercase, force it to be so. Add a contact phone number field to the Event class. Add a set method for the contact phone number field in the Event class. Whether the user enters all digits or any combination of digits, spaces, dashes, dots, or parentheses for a phone number, store it as all digits. For example, if the user enters (920) 872-9182, store the phone number as 9208729182. If the user enters a number with fewer or more…arrow_forwardProblem: To write the JUnit test cases for our methods, you need to create two test methods: testLeapYear: This method should test if the isLeapYear method returns true for a given leap year. For example, you can choose the year 2020 and verify if the method returns true for it. If it does, the test will pass. If it doesn't, the test will fail. testNotLeapYear: This method should test if the isLeapYear method returns false for a given non-leap year. For example, you can choose the year 1900 and verify if the method returns false for it. If it does, the test will pass. If it doesn't, the test will fail. --------------------------------------------------------------------------------------------------------------------------------------------------------- import static org.junit.jupiter.api.Assertions.assertTrue; import org.junit.jupiter.api.Test; public class LeapYearTest { // Test case to check if a year is a leap year @Test public void testLeapYear() { //create…arrow_forward
- Code a private method called days0fTheWeek that takes in a parameter day as a String. Based on the input argument, the method should return the appropriate day (eg. Monday, Tuesday...etc) using a "switch case" control structure. If the day is not within the range, it should return an appropriate error message to the user and vice versa. The code conditions should demonstrate mutually exclusive and collectively exhaustive. The method should only use one return statement. Example of output: days0fTheWeek("2") will return " Tuesday " in terminalarrow_forwardYour code should support the following: By default, the car's wheels should start with a pressure of 30. Every time the car drives the wheel pressure should drop by 5. The fillTires method should fill the wheels back to a pressure of 30. The Wheel class should not allow the pressure to go below 0. Any an attempt to set the pressure to a negative value should set the pressure to 0 instead. The toString methods should be written so they match the expected output of the provide Main class. The output produced by the Main class should be: Car (FR: Pressure = 30, FL: Pressure = 30, BR: Pressure = 30, BL: Pressure = 30) Car (FR: Pressure = 20, FL: Pressure = 20, BR: Pressure = 20, BL: Pressure = 20) Car (FR: Pressure = 30, FL: Pressure = 30, BR: Pressure = 30, BL: Pressure = 30) Car (FR: Pressure = 15, FL: Pressure = 15, BR: Pressure = 15, BL: Pressure = 15) Car (FR: Pressure = 30, FL: Pressure = 30, BR: Pressure = 30, BL: Pressure = 30) Car (FR: Pressure = 0, FL: Pressure = 0, BR:…arrow_forwardMethod called reverse that reverses a string passed to this method as a parameter and returns the reversed string.
