write a program using java Create a class named “Rectangle” having length and width as attribute. There should be behaviors to set the values of length and width (individually and collectively), and get their values individually. There should also be behavior to display the perimeters and area of the rectangle. Create another class named as Main which has two objects of Rectangle (

Java: Two stacks are the same if they have the same size and their elements at the corresponding positions are the same. Add the method equalStack to Class StackClass that takes as a parameter a StackClass object, say otherStack and return true if the stack is the same as otherStack. Also write the definition of method equalStack and a program to test your method. In StackClass.java, please finish method - public boolean equalStack(StackClass<T> otherStack) and testing main program public class Problem52{public static void main(String[] args){StackClass<Integer> intStack = new StackClass<Integer>(50);StackClass<Integer> tempStack = new StackClass<Integer>(50);//Please add your code here!}} public class StackClass<T> implements StackADT<T>{private int maxStackSize; //variable to store the//maximum stack sizeprivate int stackTop; //variable to point to//the top of the stackprivate T[] list; //array of reference variables //Default…

Using JAVA Language Consider a Billing class that implements an interface Payable having a method getTotalPaymentAmount(). Besides this, you have a Doctor class with private instance variables (docID, docName, and docFee) and a public getDoc() method, Patient class with private instance variables (pName, pID, pDisease), Medicine class with private instance variables (medID, medName, medQty, medPrice), and MedicalTest class with private instance variables (testID, testName, testPrice). Each of these classes has the toString() method to display the information of its object. The Billing class is having "Has A" relationship with the other four classes (Doctor, Patient, Medicine, and MedicalTest) mentioned above. The getPaymentAmount() method of Billing class returns the total billing amount that includes doc fee, medicine cost, and medical test fee that a patient has to pay. After implementing these classes, you are required to do the following in the driver class: Create an ArrayList of…

Write a program which controls a metro train and that keeps track of stations and who gets on and off.  Design and implement a class called train, which has at least the following:   At least the following attributes (you can include others):   metroID stationNum which keeps track of the station that the train is at. iii. direction which keeps track of the direction the train is travelling in. passTotal which keeps track of the number of passengers currently on the train. A default constructor which sets the metroID to a random number between 1 and 1000, the station number to 0, the direction (int), and the passTotal to 0 (train is empty). A constructor with one parameter; the parameter is the metro id. The constructor assigns the passed integer to the metroID attribute; the rest of the attributes are set as described in the default constructor. Accessor methods for each attributes. Mutator methods for each attributes. nextStation(int lastStation) which determines the next…
