Question 1 • Change the code of the setTemps method to ensure that: - hour: must be in the interval 0 >> time1.setTime (25,10,63) >>> time1 1: 11: 3 Call this method in _init_ also to correct the values if they are not correct. Add the following methods to the Time class: isBefore (t2) returns True if the time represented by self is before the time of t2, otherwise it returns False. • duration (t2) returns a new Time object with the number of hours, minutes, and seconds between self and t2. • Test your methods in the interpreter or in the main program >> t1 = Time(12,4,0) >>> t2 = Time(10,2,1) >>> t1.before(t2) >>>t2.before(12,45,2) >>> t1.before(t2) True False >>> t1.duration(t2) >>> t2.before(t1) 0:41:2

Solved in 2 steps
- 1) Through BlueJ, the class must define a method called isSpace that allows the book club staff to determine whether there is enough capacity for a group to attend. This method must take a single integer parameter representing the size of the group, and return a boolean result. The method must work as follows: If the value of the parameter is less-than or equal-to 0 then the method must return false. This case has priority over those following. If the value of the parameter is less-than or equal-to the space left in the book club (use the capacity and occupancy values in the to work this out) then the method must return true. Otherwise (i.e., if there is not space in the book club for the whole group) then the method must return false. 2) This method must not change the state of the BookClub object. In other words, both the current number of occupants and the capacity of the club must be exactly the same after it is called as it was before (Note that the return type of this method…In method cook() of the CherryPie class, perform the following tasks: Increment class attribute total_pies. Assign instance attribute num_cherries with the value of parameter cherries_used. Output 'One cherry pie made with ', followed by the value of instance attribute num_cherries, and ' cherries'.This method plays 24 rounds of rps and returns the total points earned. For each of the 24 rounds, player1’s hand gesture will be based on calling the nextInt method of the given Random object. If the next integer is even, player1 will play rock. If it is odd, player1 will play paper. Player1 never plays scissors. Player2 will play rock in the first round, paper in the second round, scissors in the third round, and repeat the cycle starting with rock again in the fourth round. The method will sum the return values for the 24 calls to rps and return the total. Note, since an invalid input is never passed in to an rps call using playRps, your return value should always be a non-negative number.
- If you don't decalre a method as public or private, would the method be defaulted to public, private or something else? Here's a portion of my code that ties to this question:static int HCPTracker(ListInterface<Card> hand) { //Method detects if a hand contains an Ace, King, Queen, or Jack int HCPCount = 0; Card aceRef = new Card(Rank.Ace,null,null); //Allows the method to detect Aces, Kings, Queens, and/or Jacks Card kingRef = new Card(Rank.King,null,null); Card queenRef = new Card(Rank.Queen,null,null); Card jackRef = new Card(Rank.Jack,null,null);1) Through BlueJ, write if the current number of shoppers is greater than or equal to the number leaving then the number of shoppers is decreased by the number leaving. Otherwise, the following error message must be printed and the number of shoppers present must be set to 0. There is an error in the number of shoppers. Use System.out.println to print the message. 2) The class must define a method called leaving that takes a single integer parameter. This represents the number of shoppers leaving the club at a particular point. You may assume that the parameter's value will always be greater than zero and you do not have to check for that. If the current number of clubbers is greater than or equal to the number leaving then the number of clubbers is decreased by the number leaving. Otherwise, the following error message must be printed and the number of clubbers present must be set to 0. There is an error in the number of shoppers. Use System.out.println to print the error message. 3)…Please help me! I have a lot of mini problems. I'm not sure how to start After #6, I have other problems. Those are : 7.) Write a method that reads a one-line sentence as input and then displays the following response: If the sentence ends with a question mark (?) and the input contains an even number of characters, display the word Yes. If the sentence ends with a question mark and the input contains an odd number of characters, display the word No. If the sentence ends with an exclamation point (!), display the word Wow. In all other cases, display the words You always say followed by the input string enclosed in quotes. Your output should all be on one line. Be sure to note that in the last case, your output must include quotation marks around the echoed input string. In all other cases, there are no quotes in the output. Your program does not have to check the input to see that the user has entered a legitimate sentence. Notes: This code requires a three-way selection statement and…

That is, the floating point result of actually dividing numerator by denominator. N.B. this method does not do any display itself, but can be called by a client program to be used in an output statement. Eg: if a client has a fraction frac that represents 1 / 2,then a method call to frac.dblValue() should return the double number 0.5.Use the client program to test this functionality; i.e. provide an outputstatement to display the double value of a fraction. import java.util.ArrayList;import java.util.Scanner; //Define the class Fractionclass Fraction{private int n, d;public Fraction(){//Initialize the valuesthis.n = this.d = 0;}public Fraction(int n, int d){//Initialize the variablesthis.n = n;this.d = d;}//Define the getter function getNum() that returns the numeratorpublic int getNum(){//Returns numeratorreturn n;}//Define the getter function getDen()…To rectify the problem identified in the following program,add a public method called isZero() to Fraction class. This method will determine if a Fraction represents a zero fraction. A zero fraction has a numerator == 0, no matter what the denominator is. isZero() method should return a Boolean result indicating a zero fraction or otherwise. The method will be used by the client class (TestFraction.java) to test whether the ‘calling fraction’ is equal to the number zero. Modify old client class so that it now loops until a fraction representing zero is entered. //TestFraction.javaimport java.util.Scanner;//test programpublic class TestFraction{ public static void main(String[] args) { //create a Scanner object Scanner in = new Scanner(System.in); //create new fraction Fraction frac = new Fraction(); //declare numerator and denominator int n=1,d; System.out.print("Enter Fraction's Numerator: "); //input numerator n =…

You can assume that all numerical values are of type float and use type hints in all your method signatures accordingly. Sorting the planets In addition your show_planets method should take a second argument, sortby, whose value is a string indicating how to sort the planets before displaying them (this is not part of the textbook description). For example, ss.show_planets(sortby = ‘distance’) displays the planets in the order of increasing distance from the sun. The default value of the sortby string parameter should be '', implying that the planets are printed without sorting (so you may get different orders based on the data structure you use for storing them). Other possible sortby parameter values are 'name', 'distance', 'mass', and 'radius' – when set, the planet names should be…
