(Date Class) Create a class called ate that includes three pieces of information as data members—a month (type int), a day (type int) and a year (type int). Your class should have a constructor with three parameters that uses the parameters to initialize the three data members. For the purpose of this exercise, assume that the values provided for the year and day are correct, but ensure that the month value is in the range 1–12; if it isn’t, set the month to 1. Provide a set and a get function for each data member. Provide a member function displayData that displays the month, day and year separated by forward slashes (/). Write a test

- Problem 1: Java programComplete the Clothing class, the class should have the following instance variables, constructor(s) and instance methods:- An instance variable of type double named price.- An instance variable of type String named type.- An instance variable of type String named size.- A default “no-arg” constructor that sets the price to 29.9, the type to “TShirt” and the size to “Medium”. - An overloaded constructor that takes three parameters and set the instance variables accordingly. - A method named increasePrice that takes no parameters and returns no value, the method increases the instance variable price by 5.- An overloaded method increasePrice that takes a double parameter xand returns no value, the method increases the instance variable price by the value of parameter x.- A method named details which takes no parameters, returns no value, the method prints the Clothing item details in the format shown in the sample output.- Your output should look exactly the same…arrow_forwardBriefly explain parameterarrow_forwardC++ please, Specify, design, and implement a class that can be used in a program that simulates a combination lock. The lock has a circular knob, with the numbers 0 through 39 marked on the edge, and it has a three-number combination, which we'll call x, y, z. To open the lock, you must turn the knob clockwise at least one entire revolution, stopping with x at the top; then turn the knob counter-clockwise; stopping the second time that y appears at the top; finally turn the knob clockwise again, stopping the next time the z appears at the top. At this point the lock will be open. Your lock class should have a constructor that initializes the three-number combination (use 0,0,0 for default arguments). Also provide member functions: a. To alter the lock's combination b.To turn the knob in a given direction until a specified number appears on top c. To close the lock d. To attempt to open the lock e. To inquire the status of the lock (open or shut) f. To tell you what number is currently…arrow_forward

Group of answer choices A function’s argument is referred to as the formal argument to distinguish it from the value that is passed in during the function call. The parameter is the passed value. They are identical but using different terms. A function’s parameter is used for passing by reference. The argument is used for passing by value.
