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

inessss [21]

Answer:

The advantage of returning a structure type from a function when compared to returning a fundamental type is that

e. a and b only.

Explanation:

One advantage of returning a structure type from a function vis-a-vis returning a fundamental type is that the function can return multiple values. The second advantage is that the function can return can an object. This implies that a function in a structure type can be passed from one function to another.

Write a C program that does the following: Creates a 100-element array, either statically or dynamically Fills the array with ra

ANEK [815]

Answer:

Following are the code to this question:

#include <iostream>//header file

using namespace std;

int main()//main method

{

int axb[100];//defining 1-array of 100 elements

int odd_axb[100], even_axb[100];//defining two array that holds 100-elements

int i,size=0,size1=0;

for(i = 0; i < 100; i++)//defining for loop to assign value in array

{

axb[i] = rand() % 100 + 1;//using rand method to assign value with random numbers between 1 and 100

}

for(i = 0; i < 100; i++)//defining for loop that seprates array value in odd and even array

{

if(axb[i] % 2 == 0)//checking even condition

{

even_axb[size++] = axb[i];//holding even number

}

else//else block

{

odd_axb[size1++] = axb[i];//holding Odd number

}

//printing values

cout << "Odd array: ";//print message

for(i = 0; i <size1; i++)//use for loop for print odd numbers

{

cout << odd_axb[i]<<" ";//printing values

}

cout <<"\n\n"<< "Even array: ";//print message

for(i = 0; i <size; i++)//use for loop for print even_axb numbers

{

cout << even_axb[i] << " ";//printing values

}

return 0;

}

Output:

Odd array: 87 87 93 63 91 27 41 27 73 37 69 83 31 63 3 23 59 57 43 85 99 25 71 27 81 57 63 71 97 85 37 47 25 83 15 35 65 51 9 77 79 89 85 55 33 61 77 69 13 27 87 95

Even array: 84 78 16 94 36 50 22 28 60 64 12 68 30 24 68 36 30 70 68 94 12 30 74 22 20 38 16 14 92 74 82 6 26 28 6 30 14 58 96 46 68 44 88 4 52 100 40 40

Explanation:

In the above-program, three arrays "axb, odd_axb, and even_axb" is defined, that holds 100 elements in each, in the next step, three integer variable "i, size, and size1" is defined, in which variable "i" used in the for a loop.

In the first for loop, a rand method is defined that holds 100 random numbers in the array, and in the next, for-loop a condition statement is used that separates even, odd number and store its respective array, and in the last for loop, it prints its store values
