In Java: Write a class called Shelf that contains instance data that repre-sents the length, breadth, and capacity of the shelf.

disa [49]

Answer:see explanation

Explanation:

Hello, the solution is the following:

in a file named Shelf.java :

public class Shelf{

int length;

int breadth;

int capacity;

boolean occupied;

Shelf(int length,int breadth, int capacity){

this.length = length;

this.breadth = breadth;

this.capacity = capacity;

this.occupied = false;

}

//set methods

public void setLength(int length){

this.length = length;

}

public void setBreadth(int breadth){

this.breadth = breadth;

}

public void setCapacity(int capacity){

this.capacity = capacity;

}

public void setOccupied(boolean occupied){

this.occupied = occupied;

}

//get methods

public int getLength(){

return this.length;

}

public int getBreadth(){

return this.breadth;

}

public int getCapacity(){

return this.capacity;

}

public boolean getOccupied(){

return this.occupied;

}

//tostring method

public String toString(){//overriding the toString() method

return "Shelf: \n"+" length: "+Integer.toString(this.length)+" breadth: "+Integer.toString(this.breadth)+" capacity: "+Integer.toString(this.capacity)+" occupied: "+Boolean.toString(this.occupied);

}

in another file named ShelfCheck.java

public class ShelfCheck {

public static void main(String[] args) {

Shelf s1=new Shelf(100,150,300);

Shelf s2=new Shelf(200,200,234);

Shelf s3=new Shelf(300,222,543);

Shelf s4=new Shelf(400,434,654);

System.out.println(s1);

System.out.println(s2);

System.out.println(s3);

System.out.println(s4);

s4.setLength(5);

System.out.println(s4);

s2.setBreadth(2);

System.out.println(s2);

s3.setCapacity(1);

System.out.println(s3);

s1.setOccupied(true);

System.out.println(s1);

}

OUTPUT:

Shelf:

length: 100 breadth: 150 capacity: 300 occupied: false

Shelf:

length: 200 breadth: 200 capacity: 234 occupied: false

Shelf:

length: 300 breadth: 222 capacity: 543 occupied: false

Shelf:

length: 400 breadth: 434 capacity: 654 occupied: false

Shelf:

length: 5 breadth: 434 capacity: 654 occupied: false

Shelf:

length: 200 breadth: 2 capacity: 234 occupied: false

Shelf:

length: 300 breadth: 222 capacity: 1 occupied: false

Shelf:

length: 100 breadth: 150 capacity: 300 occupied: true

Discuss how does a Modulus Operator function

aliya0001 [1]

Answer:

Modulus operator are useful in many circumstances and it is commonly used to generate the random number. It basically reduce the number into random number in a small range.

It also describe that whether, the one number is a factor of another or not.

In C language, the modulus operator provide the remainder after diving the greater value with the smaller value. If the smaller number are divided by the larger number then, the quotient become zero.

Explanation:

Summary:

The data set include two dependent variables which states High School annual earnings and BS annual earnings in the same small firm. Firstly, I used density plot function to view the distribution of two sets of variables. Secondly, I tested the skewness and kurtosis.Skewness of High School is -0.24041 which is left tail. Skewness of BS is 0.53476 which is right tail.Kurtosis of High School is 2.5695 which lower than 3 is platykurtic. Kurtosis of BS is 3.6449 which larger than 3 is leptokurtic. Thirdly, the sample population is 39 for each and has unknow standard deviation, so that I’m going to use t-test to perform the comparing analysis. The result shows p-value which equal to 0.866 is larger than significant value(alpha = 0.05). To the concludsion, there is no difference between yearly earnings of High School and of BS at a small firm.
