Write a method that sums all the numbers in the major diagonal in an n x n matrix of double values using the following header: public static double sumMajorDiagonal(double[][] m) Write a test program that first prompts the user to enter the dimension n of an n x n matrix, then asks them to enter the matrix row by row (with the elements separated by spaces). The program should then print out the sum of the major diagonal of the matrix.
Answers
Answer:
Following are the code to this question:
import java.util.*; //import package for user input
public class Main //defining main class
{
public static double sumMajorDiagonal(double [][] m) //defining method sumMajorDiagonal
{
double sum = 0; //defining double variable sum
int i, j; //defining integer variable
for(i = 0; i <m.length; i++) //defining loop to count row
{
for(j = 0; j < m.length; j++) //defining loop to count column
{
if(i == j) //defining condition to value of i is equal to j
{
sum=sum+ m[i][j]; //add diagonal value in sum variable
}
}
}
return sum; //return sum
}
public static void main(String args[]) //defining main method
{
int n,i,j; //defining integer variable
System.out.print("Enter the dimension value: "); //print message
Scanner ox = new Scanner(System.in); //creating Scanner class object for user input
n = Integer.parseInt(ox.nextLine()); //input value and convert value into integer
double m[][] = new double[n][n]; //defining 2D array
for(i = 0; i < m.length; i++)
{
String t = ox.nextLine(); // providing space value
String a[] = t.split(" "); // split value
for(j = 0; j < a.length; j++) //defining loop to count array value
{
double val = Double.parseDouble(a[j]); //store value in val variable
m[i][j] = val; //assign val in to array
}
}
double d_sum = sumMajorDiagonal(m); //call method store its return value in d_sum variable
System.out.println("diagonal matrix sum: "+ d_sum); //print sum
}
}
output:
Enter the dimension value: 3
1 2 3
1 2 3
1 2 4
diagonal matrix sum: 7.0
Explanation:
Program description:
In the given java language code, a method "sumMajorDiagonal" is declared, that accepts a double array "m" in its parameter, inside the method two integer variable "i and j" and one double variable "sum" is defined, in which variable i and j are used in a loop to count array value, and a condition is defined that checks its diagonal value and use sum variable to add its value and return its value. In the main method first, we create the scanner class object, that takes array elements value and passes into the method, then we declared a double variable d_sum that calls the above static method, that is "sumMajorDiagonal" and print its return value with the message.Related Questions

What is random random () Python?Create a list of random numbers in Python starting from "start" to "end" with the supplied lower and upper bounds.
Here, we'll generate any random number in Python using a variety of techniques.
One of Python's built-in modules, the Random module, is used to produce random integers.
Since these numbers are not completely random, they are pseudo-random.
Using this module, one can generate random integers, print a random value for a list or string, among other random operations.
Examples:
Number: 10, Start: 20, End: 40
Output: [23, 20, 30, 33, 30, 36, 37, 27, 28, 38]
Explanation: Ten random numbers in the [20, 40] range are included in the result.
Enter the following information: num = 5, start = 10, and end = 15.
Output: [15, 11, 15, 12, 11]
Explanation: The result includes 5 random numbers between [10, 15].

Calculate the number of half dollars, quarters, dimes, nickels, and pennies, use division and modulo operator

Let me demonstrate calculating the half_dollars:
Let's say the user enter 134 for the change.
half_dollars = int(change / 50) → int(134/50) → int(2.68) = 2
change %= 50 (same as change = change % 50) → 134 % 50 → 34

Given the following code, what logic would you need to include to double all odd values stored within the array:
int[] myArray = {1,2,3,13,5,6,7,8,9,17};
for (int i = 0; i < myArray.length; i++) {
//your code goes here
}
NOTE: Your response should be just the missing logic--not the entire problem set.
Answers
Answer:
if (myArray[i] % 2 != 0) {
myArray[i] *= 2;
System.out.println(myArray[i]);
}
Explanation:
Insert this into your for loop. Basically what it does is check if the array value at a given index is an odd value. For that I got the mod of number divided by 2 (array % 2) and if the mod is different than zero then the number is "odd".
than I multiplied that value by to, this code:
myArray[i] *= 2;
is the same as doing this:
myArray[i] = myArray[i] * 2;
I have just shortened, but you can do the latter just in case you haven't learned yet.
Anyway, I multiplied by 2 in order to double the values as the question tells.
Then I simply printed these doubled odd values.
But just in case you're not sure, the whole thing goes like this, you can test in your IDE or whatever you are using:
public class Main {
public static void main(String[] args) {
int[] myArray = {1,2,3,13,5,6,7,8,9,17};
for (int i = 0; i < myArray.length; i++) {
if (myArray[i] % 2 != 0) {
myArray[i] = myArray * 2;
System.out.println(myArray[i]);
}
}
}
}
To double the odd values in the array, it is essential to first identify the odd values, then multiply each value by 2. Hence, the missing logic is ;
if (myArray[i] % 2 != 0) {
myArray[i] *= 2;
System.out.println(myArray[i]);
}
Odd values leaves a remainder when divided by 2 otherwise the value is even ; hence, using the if statement, check if, the value in the array leaves a remainder. If it does, Using, the index value of the value, update the odd value by Multiplying the initial value by 2.Hence, the missing logic.

At the end your program will output the following report:
Number of occurrences for the alphabets:
a was used – times.
b was used – times.
c was used – times…. …and so, on

paragraph. Your program should keep a counter associated with each letter of the
alphabet (26 counters) [Hint: Use array]
Your program should also print a histogram of characters count by adding
a new function print Histogram (int counters []). This function receives the
