Declare a MyStruct variable and initialize the second field to an array containing all zeros.

please help me with this JAVA Programming challenge from chapter 7. Below is the challenge question Thank you 17. 2D Array Operations Write a program that creates a two-dimensional array initialized with test data. Use any primitive data type that you wish. The program should have the following methods: getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array. getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the...

You are given the following two dimensional arrays of people and their birth months: String [][] people = {{June, May, March, June, May, March, February, June, May, January, May, March}, {John, Mary, Peter, Bob, Sam, Dan, Judith, Gary, Tiff, Suzy, Jim, Jane}} 1) Create an enum type for the the first six months of the year 2) Randomly select a month from this enum 3) Loop through the array of people and make a list of all the people whose birthdays correspond to the month that was randomly chosen above. I ONLY NEED THE ANSWERS TO 2 AND 3. Please provide the code

Code Should Be in Java: use loops, if statements, arrays, scanner etc Write an application that stores at least five different college courses (such as CIS101), the time it first meets in the week (such as Mon 9 am), and the instructor (such as Johnson) in a two-dimensional array. Allow the user to enter a course name and display the corresponding time and instructor. If the course exists twice, display details for both sessions. If the course does not exist, display an error message. Save the file as TimesAndInstructors.java

Write a piece of code that declares an array variable named data with the elements 7, -1, 13, 24, and 6. Use only one statement to declare and initialize the array.

In visual basic Write the code that will sequentially search through the array strFirstNames and will print out the word "Found" if the name "Brian" is in the array.

Code for this in C: You have already created an array named NUMBERS with 20cells. You are to initialize all of the cells with odd subscripts to 1 and all of the cells with even subscripts to 2.

17. Phone Book ArrayList Write a class named PhoneBookEntry that has fields for a person's name and phone number. The class should have a constructor and appropriate accessor and mutator methods. Then write a program that creates at least five PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.

When you pass an array as an argument, what is passed into the parameter variable?

The intNum array is declared as follows: Dim intNum(,) As Integer = {{6, 12, 9, 5, 2}, {35, 60, 17, 8, 10}}. The intNum(1, 4) = intNum(1, 2) - 5 statement will _____________________. a. replace the 10 amount with 12 b. replace the 5 amount with 7 c. replace the 2 amount with 4 d. None of the above.

Declare a char array named delimiters and initialize it with the comma and semicolon characters.

10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated...

Java code: declare an array of type Animal and create an array for this variable which can hold 5 animals.
