Write down a class Time having fields (hrs, mins, secs), containing no argument constructor, three arguments constructor and copy constructor. Also write down a method inc_time() that increments seconds by 1 if seconds are equal to 60 then increment minutes by 1 and set seconds to 0. If minutes become equal to 60 then increment hrs by 1 and set minutes to 0. Write down a method that compares two objects and return true if they are equal else returns false. C++

This is the first exercise for the TODO comments in the main method. Complete the actions described in these comment lines in the main method:// TODO: Add a public static constant called PRIMARY_NAME// to the Student class. Set the name of the Primary to// a real University. In other words: Add a public static final String variable called PRIMARY_NAME to the fields of the Student class. Initialise the variable in the same line it is declared (not in the constructor) to the name of a real Primary. Add code to the Main class in this project to access the PRIMARY_NAME field and print it out. Remember that, because the field is public, it can be accessed directly from another class without having to provide a getter method for it. In the lecture discussing static fields and methods, we showed that the nextID field in the Student class is used to store the value of the next…
Java Programming problem Create a checking account class with three attributes: account number, owner’s name, and balance. Create constructor, getters and setters. If one is to set the initial balance of an account as a negative value in a setter or a constructor, remind the user about the error and set it as 0. Create a CheckingAccountDemo class, and create a main method in which Ask for the name, account number, and initial balance for one account from the keyboard input. With these input values as arguments in a call to the constructor, create a CheckingAccount object. Print the summary of this account that includes information on the name, account number, and balance by calling the getters.
Modify the student class presented in this chapter as follows. Each student object should also contain the scores for three tests. Provide a constructor that sets all instance values based on parameter values. Overload the constructor such that each test score is assumed to be initially zero. Provide a method called setTestScore that accepts two parameters: the test number (1 through 3) and the score. Also provide a method called getTestScore that accepts the test number and returns the appropriate score Provide a method called average that computes and returns the average test score for this student. Modify the toString method such that the test scores and average are included in the description of the student. Modify the driver class main method to exercise the new Student methods. (Java)

Write a method toString() for the Cow class which displays information about a Cow object. The method should consider the following: • If the Cow's stomach value is 100, the output should say that the Cow is full • If the Cow's stomach value is below 100 but above 50, no information about the Cow's stomach should be given • If the Cow's stomach value is below 50 but above 10, the output should mention that the cow is hungry • If the Cow's stomach value is below 10, the output should mention that the cow is starving. Example output: First Cow is full. Second Cow Third Cow is hungry. Fourth Cow is starving!
Create a method "public void giveRaise(int percentage)" in the Employee class. This method should increase the salary member by the percentage specified in the parameter. In the main method: 1. Create an Employee object. Print out its toString() result. Call giveRaise with 10%. 2. Print out its toString() result.
Write a program that test methods in the class. Hint: the employee deserved retirement if he has year of Service >25 or his age >=65. 5. Design a class named Mylnteger. The class contains: An int data field named value(int) Methods isEven() and isOdd(0 that return true if the value is even or odd respectively. Write a program that test methods in the class.
Given a variable Animal pet - which currently holds a reference to a Animal object, and two methods inside the Animal class with the headers: 1. public void setOwner(String ownerName, String address, boolean hasGarden) 2. public int getPetToHumanAge(String species, int petAge) 3. %should be static, but ok... Write two possible calls for each of these methods.
The formula for converting a temperature from Fahrenheit to Celsius is: C = 5/9(F – 32) where F is the temperature in Fahrenheit and C is the temperature in Celsius. Write a class called TemperatureConversion that includes methods that: • Convert Celsius to Fahrenheit. The Celsius temperature is passed as a parameter and it returns the corresponding Fahrenheit temperature. • Convert Fahrenheit to Celsius. The Fahrenheit temperature is passed as a parameter and it returns the corresponding Celsius temperature. Demonstrate the methods by using loops to display the Fahrenheit temperatures 32 through 212 and their Celsius equivalents and the Celsius temperatures between 0 and 100 and their Fahrenheit equivalents. in c#
The Hal9000 has one constructor which takes a String parameter of a name of the crew member it is interacting with. It has methods: public String getName() which gets the name public void setName(String newName) which sets a new name public String greet() which returns a string consisting of "Greetings, name" where name is the name supplied in the constructor. public String reportStatus() which returns a string consisting of "All systems are operating normally, name" where name is the name supplied in the constructor. public String execute(String command) which returns a string consisting of "I am sorry, name. I can't " + command where name is the name supplied in the constructor and command is the parameter.
Modify this class by: 1. Suppose the bank wants to keep track of how many accounts exist. A. Do you need a static variable or a regular variable to save how many accounts have been created? Declare it and name the variable as numAccounts. It should be initialized to 0 (since no account exists initially). B. Update this variable in the constructor. (Ask the instructor if you do not know how) C. Add a method getNumAccounts that returns the total number of accounts. Decide if this method should be static – is the information related to a single account or is it for the entire class? Does this method manipulate a static variable? Complete this method. 2. Use the driver class TestAccounts1.java to test your modified Account class. Complete the code as instructed. 3. Add a method void close() to your Account class. This method should close the current account by appending “CLOSED” to the account name and setting the balance to 0. Also, decrement the total number of accounts. Should this…
