In this lab, you will create a programmer-defined class and then use it in a Java program. The program should create two Rectang
prohojiy [21]

Answer:

class Rectangle{

//private attributes of length and width

private double givenLength;

private double givenWidth;

// constructor to initialize the length and width

public Rectangle(double length, double width){

 givenLength = length;

 givenWidth = width;

}

// setter method to set the givenlength

public void setGivenLength(double length){

 givenLength = length;

}

// setter method to set the givenWidth

public void setGivenWidth(double width){

 givenWidth = width;

}

// getter method to return the givenLength

public double getGivenLength(){

 return givenLength;

}

// getter method to return the givenWidth

public double getGivenWidth(){

 return givenWidth;

}

// method to calculate area of rectangle using A = L * B

public void calculateArea(){

 System.out.println("The area of the rectangle is: " + getGivenLength() * getGivenWidth());

}

// method to calculate perimeter of rectangle using P = 2 * (L + B)

public void calculatePerimeter(){

 System.out.println("The perimeter of the rectangle is: " + 2 * (getGivenLength() + getGivenWidth()));

}

}

public class MyRectangleClassProgram{

public static void main(String args[]){

//rectangle1 object is created

Rectangle rectangle1 = new Rectangle(10.0, 5.0);

//rectangle2 object is created

Rectangle rectangle2 = new Rectangle(7.0, 3.0);

//area for rectangle1 is calculated

rectangle1.calculateArea();

//perimeter for rectangle1 is calculated

rectangle1.calculatePerimeter();

//area for rectangle2 is calculated

rectangle2.calculateArea();

//perimeter for rectangle2 is calculated

rectangle2.calculatePerimeter();

}

}

Suppose that we pick the following three tuples from a legal instance of a relation S (S has 100 tuples in total). Relation S ha
AysviL [449]

Answer:

The correct answer is BC → A, A does not hold over S. we noticed the tuples (1 ,2 ,3 ) and (4 ,2 ,3) which can hold over S)

Explanation:

Solution

No, since in this case the instance of S is provided. so such particular dependencies are unable to breach through such instance, but unable to tell which the dependencies hold towards S.

A functional dependency holds towards only when a relation forms a statement regarding the complete allowed instances of relation.
