Alphabet Random Walk • Write a program to generate a random walk that spans a 10*10 character array (The initial values of the elements are all.). The program must randomly walk from one element to another, moving one element position up, down, left or right each time. The elements that have been visited are labeled with the letters A through Z in the order in which they were visited

Lw//. Two-Dimensional ArrayInstruction:Create a java program that generates elements (randomly from 10 – 75) of a 2-dimensional array (5x5) using the Random Class then perform the following:1) Output the array elements2) Output the sum of prime numbers in the array3) Output the elements in the main diagonal.4) Output the sum of the elements below the diagonal.5) Output the sum of the elements above the diagonal.6) Output the odd numbers below the diagonal.7) Output the even numbers above the diagonal. NOTE: Please do not use the array methods available on the internet. Use the for loop, while loop or do-while loop statement in your codes..

8. Grade Book A teacher has five students who have taken four tests. The teacher uses the following grading scale to assign a letter grade to a student, based on the average of his or her four test scores: Test Score Letter Grade 90–100 A 80-89 B 70-79 C 60-69 D 0-59 Write a class that uses a String array or an ArrayList object to hold the five students' names, an array of five characters to hold the five students' letter grades, and five arrays of four doubles each to hold each student's set of test scores. The class should have methods that return a specific student's name, the average test score, and a letter grade based on the average. Demonstrate the class in a program that allows the user to enter each student's name and his or her four test scores. It should then display each student's average test score and letter grade. Input Validation: Do not accept test scores less than zero or greater than 100.

JAVA CODE PLEASE Functions with 2D Arrays Quiz by CodeChum Admin Write a program that asks the user for the row and column size of a 2D array and asks the user for the elements. Write the total of the sum of each row multiplied with the row number. Example: 1 2 3 -> (1+2+3) * 1 = 6 4 5 6 -> (4+5+6) * 2 = 30 7 8 9 -> (7+8+9) * 3 = 72 total: 108 Input 1.

Find primes This program creates and displays a 5x10 matrix(5 rows and 10 columns) of random integers between 1 and a maximum value(user input). Hint: Use the random library to generate each number and place it into your 2D list. The program then counts the number of prime numbers in each row of the array and displays this number, along with the found primes. The program finally displays the total number of prime numbers in the matrix.

Variables Primitive Write a java program that asks the user to enter 3 integers. Add the integers and display "The total is " the result Reference Write a java program that asks the user for their first name and last name. Display "Your full name is " the first name and last name Arrays One-dimensional Write a java program that creates an array of integers called numbers and contains five elements. Then use a for loop to print them out using println(). Two-dimensional submit your code for the total of rows and total of columns here

Multiple Choice Identify the choice that best completes the statement or answers the question. 1. A list of numbers has n elements, indexed from 1 to n. The following algorithm is intended to display the number of elements in the list that have a value greater than 100. The algorithm uses the variables count and position. Steps 3 and 4 are missing. Step 1: Set count to 0 and position to 1. Step 2: If the value of the element at index position is greater than 100, increase the value of count by 1. Step 3: (missing step) Step 4: (missing step) na viliog dbod cour pot Step 5: Display the value of count. Which of the following could be used to replace steps 3 and 4 so that the algorithm works as intended? Step 3: Repeat step 2 until the value of count is greater than 100. Step 3: Repeat step 2 until the value of position is greater than n. a. c. Step 4: Increase the value of position by Step 4: Increase the value of count by 1. 1. b. Step 3: Increase the value of position by d. Step 3:...
