If statement 3 is uncommented, the code prints "3" to the output. This ode does not compile. 2.2- Try to do the following: Declare an integer variable called myInt in the ClassB; the variable myInt should be accessible through the object cb. Write a statement in ClassA to check out the accessibility of your variable.arrow_forwardObject Oriented Programming in JAVA You are part of a team writing classes for the different game objects in a video game. You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object. Also write a main method for each class in which that class is…arrow_forwardclass Course { private String courseNumber; private String courseName; private int creditHrs; public Course (String number, String name, int creditHrs){ this.courseNumber = number; this.courseName = name; this.creditHrs = creditHrs; } public String getNumber() { return courseNumber; } public String getName() { return courseName; } public int getCreditHrs() { return creditHrs; } public void setCourseNumber(String courseNumber) { this.courseNumber = courseNumber; } public void setCourseName(String courseName) { this.courseName = courseName; } public void setCreditHrs(int creditHrs) { this.creditHrs = creditHrs; }} class Student { private String firstName; private String lastName; private String gender; private String phoneNumber; private String email; private String jNumber; protected ArrayList<MyCourse> courseList; public String…arrow_forward
