Complete the code for the following program. You are provided with an abstract
class called abst. Create a class that will be a child of abst and it will be called
usesAbst. Your program will have an int variable called value, and all the
appropriate methods, as well 2 constructors. The first constructor will simply set
the variable value to 0. The second constructor will set the variable value to equal
a passed in parameter. You do not have to comment your code.
public abstract class abst{
public abst () {
}
//Outputs to the screen the message Hello
public abstract void sayHello ();
//returns the stored int value
public abstract int getValue ();
//sets the int value to x
public abstract void setValue (int x);
//Outputs to the screen the message Another method
public void output () {
System.out.println("Another method");
public String tostring () {
return "This is an abstract class";
}
Novice: How can i access a main class objects from outside the function? / Better Alternative?
If i have 4 Student objects how can i print the information for the specific object given one parameter about the class, like the students Idnumber.
What i came up with was making a checkId void function that takes the user input and runs an if else chain checking if the Id belongs to student 1-4 then printing the details of that classes object with the void function print. ideally i would want the if-else chain in the checkId function to call the print( student1-4) class object but im not sure how to properly do that.
i dont think this is the best way to go about it, if you have any recommendations or alternatives please help me out.

2. This question involves the implementation of a fitness tracking system that is represented by the
StepTracker class. A StepTracker object is created with a parameter that defines the minimum
number of steps that must be taken for a day to be considered active.
The StepTracker class provides a constructor and the following methods.
addDailySteps, which accumulates information about steps, in readings taken once per day
activeDays, which returns the number of active days
averageSteps, which returns the average number of steps per day, calculated by dividing the
total number of steps taken by the number of days tracked
The following table contains a sample code execution sequence and the corresponding results.

- shows the complete anagram.cpp program. Use a class to represent the word to be anagrammed. Member functions of the class allow the word to be displayed, anagrammed, and rotated. The main() routine gets a word from the user, creates a word object with this word as an argument to the constructor, and calls the anagram() member function to anagram the word.arrow_forwardWhat statements about the destructor of an object are accurate? a. The destructor of a class is a member function that is automatically activated when an object becomes inaccessible. b. The destructor has no arguments and its name must be the character ~ followed by the class name (e.g., ~bag for the bag class). c. Because the destructor is automatically called, programs rarely make explicit calls to the destructor, and we generally omit the destructor from the documentation that tells how to use the class. d. The primary responsibility of the destructor is simply releasing dynamic memory. c & d a, b, & c b & c a & b a, b, c, & darrow_forwardProblem Class In this exercise, you are going to create the Problem class. The Problem class is used to help simulate a math fact, for example: 2 + 5 = Your class needs to contain two contructors, one that takes String, int, int that represts the operator sign(+, -, *, or /), the minimum, and maximum values for the number range, and a second constructor that takes only a String that represents the operator sign. For the second constructor, the minimum should default to zero and the maximum to ten. Your Problem object should generate 2 random integers between the minimum and maximum values (inclusively). Each Problem object should only have one set of numbers that do not change. While you may include additional helper methods, two methods need to be available to the user. The first is the answer method that should return a double that represents the answer to the problem. The second is the toString that should return a String that represents the problem.

- 1- Create a hierarchy of Java classes as follows: MyRectangle is_a MyShape; MyOval is a MyShape. Class MyPoint: Class MyPoint is used by class MyShape to define the reference point, p(x, y), of the Java display coordinate system, as well as by all subclasses in the class hierarchy to define the points stipulated in the subclass definition. The class utilizes a color of enum reference type MyColor, and includes appropriate class constructors and methods. The class also includes draw and toString methods, as well as methods that perform point related operations, including but not limited to, shift of point position, distance to the origin and to another point, angle [in degrees] with the x-axis of the line extending from this point to another point. Enum MyColor: Enum MyColor is used by class MyShape and all subclasses in the class hierarchy to define the colors of the shapes. The enum reference type defines a set of constant colors by their red, green, blue, and opacity, components,…arrow_forwardWrite a class ‘Box’ which has three members height, width and depth; To set values and use these members, write mutator and accessor functions for these members.

The name of the class is RightTriangle 2. The class has member variables base and height 3. The class has a constructor that initializes base and height 4. The class has accessors and mutators for base and height 5. The class has a toString method that produces String representation of a RightTriangle like the following example for a triangle with base 12 and height 10. Base : 12 Height 10 6. The class has a method called findArea to compute the area of the right triangle. Here is a suggested implementation. public double findArea() { return 0.5* this.base*this.height; } 7. The class using proper naming conventions Write a test class called RightTriangleTest that conforms to the following: 1. Create an object with base = 10 and height = 20, for example myTriangle. 2.

- Create a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1.
