Write a Java program in jGRASP that creates a 2D integer array of 5 rows and 20 columns, fills it with increasing integer values

Alex73 [517]

Answer:

As per the question we need to make 5 rowa and 2o columns, in this we have total element 100 so range should be 0 to 99, but we are suggested to keep range 0 to 59, so i have kept the elementns in the range, but if it was a typo in the question for range you do not need to reset the k with zero.

Explanation:

//create a new class TestArray

public class TestArray {

//define main method

public static void main(String[] args) {

//declare a 2D array of given size i.e. 5 rows and 20 columns

int arr[][] = new int[5][20];

//declare an integer variable k and initialize it with zero, this will used to initialize the array from 0 to 99

int k = 0;

//for loop for rows

for (int i = 0; i < 5; i++) {

//for loop for columns

for (int j = 0; j < 20; j++) {

//initialize arr with the current value of k

arr[i][j] = k;

//once k is 59 set it zero again as we are not going beyond 59

if(k == 59)

k = 0;

//increment value of k with 1

k++;

}

//print the element from the array one by one

//for loop for rows

for (int i = 0; i < 5; i++) {

//for loop for columns

for (int j = 0; j < 20; j++) {

//print the current element of array and an space with it

System.out.print(arr[i][j]+" ");

}

// move the cursor to new line

System.out.println();

}

What steps do you need to take to register

ratelena [41]

Depends on what you are registering for but you will most likely need your First and last Name, Email, and a secure password... that's for most signups.

5)What are the differences in the function calls between the four member functions of the Shape class below?void Shape::member(S

Stells [14]

Answer:

void Shape :: member ( Shape s1, Shape s2 ) ; // pass by value

void Shape :: member ( Shape *s1, Shape *s2 ) ; // pass by pointer

void Shape :: member ( Shape& s1, Shape& s2 ) const ; // pass by reference

void Shape :: member ( const Shape& s1, const Shape& s2 ) ; // pass by const reference

void Shape :: member ( const Shape& s1, const Shape& s2 ) const ; // plus the function is const

Explanation:

void Shape :: member ( Shape s1, Shape s2 ) ; // pass by value

The s1 and s2 objects are passed by value as there is no * or & sign with them. If any change is made to s1 or s2 object, there will not be any change to the original object.

void Shape :: member ( Shape *s1, Shape *s2 ) ; // pass by pointer

The s1 and s2 objects are passed by pointer as there is a * sign and not & sign with them. If any change is made to s1 or s2 object, there will be a change to the original object.

void Shape :: member ( Shape& s1, Shape& s2 ) const ; // pass by reference

The s1 and s2 objects are passed by reference as there is a & sign and not * sign with them. If any change is made to s1 or s2 object.

void Shape :: member ( const Shape& s1, const Shape& s2 ) ; // pass by const reference

The s1 and s2 objects are passed by reference as there is a & sign and not * sign with them. The major change is the usage of const keyword here. Const keyword restricts us so we cannot make any change to s1 or s2 object.

void Shape :: member ( const Shape& s1, const Shape& s2 ) const ; // plus the function is const

The s1 and s2 objects are passed by reference as there is a & sign and not * sign with them. const keyword restricts us so we cannot make any change to s1 or s2 object as well as the Shape function itself.

Read one positive integer n. Then create an n X n two-dimensional array and write the code that stores integers from 1 to n2 as

marysya [2.9K]

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

int n;

Scanner input = new Scanner(System.in);

System.out.print("Size of array: ");

n = input.nextInt();

int count = 1;

int[][] arr = new int[n][n];

for(int i = 0; i<n;i++){

for(int j = 0; j<n;j++){

arr[i][j] = count;

count++; } }

for(int i = 0; i<n;i++){

for(int j = 0; j<n; j++){

System.out.printf(arr[i][j]+" "); }

System.out.println(); } }}

Explanation:

This declares the size of the array

int n;

Scanner input = new Scanner(System.in);

This prompts the user for size of array

System.out.print("Size of array: ");

This gets input for size of array

n = input.nextInt();

This initializes the array element to 1

int count = 1;

This creates a 2d array

int[][] arr = new int[n][n];

This iterates through the rows

for(int i = 0; i<n;i++){

This iterates through the columns

for(int j = 0; j<n;j++){

This populates the array

arr[i][j] = count;

count++; } }

The following nested loop prints the array elements

for(int i = 0; i<n;i++){

for(int j = 0; j<n; j++){

System.out.printf(arr[i][j]+" "); }

System.out.println(); } }}
