- 1- Arrays can be created to store values of multiple data types at one place. True False 2- To copy the contents of one array to another you must copy the individual array elements. True Falsearrow_forward• • Asks the user for their name and store it in an array Asks the user for their age and store it in a variable Determines how many years before they can retire at age 67. If user is 67 then it will indicate that the user should retire now. If user is over 67 it will indicate that the user should have already retired If the user is under 67 then it will indicate number of years before retirement Ends with a thank you message. Example of Output Welcome to nameage Please enter name: (user enters a value like Pat) Please enter your age: (user enters a value like 69) Hi Pat. You should already be retired. Thank you for using nameage. Bye!arrow_forwardThe intNum array is declared as follows: Dim intNum(,) As Integer = {{6, 12, 9, 5, 2}, {35, 60, 17, 8, 10}}.

- # Declare a named constant for array size here. MAX_AVERAGES = 8 # Declare array here. # Write a loop to get batting averages from user and assign to array. averageString = input("Enter a batting average: ") battingAverage = float(averageString) # Assign value to array. # Assign the first element in the array to be the minimum and the maximum. minAverage = averages[0] maxAverage = averages[0] # Start out your total with the value of the first element in the array. total = averages[0] # Write a loop here to access array values starting with averages[1] # Within the loop test for minimum and maximum batting averages. # Also accumulate a total of all batting averages. # Calculate the average of the 8 batting averages. # Print the batting averages stored in the averages array. # Print the maximum batting average, minimum batting average, and average batting average.

Planets: Venus Earth Mars Jupiter Saturn Uranus Neptunearrow_forwardThe logic will allow the user to: Load a single dimensional array of size 50 with a random number The random number will range from 1 to 1,000 (you may have duplicate values) Find the highest value and the index location that it was in Find the smallest value and the index location that it was in Display the array’s contents. Display the highest value and its index location Display the lowest value and its index location Allow the user to execute this application multiple times (some sort of loop?) You will need one for loop to load the array as well as one or two for loops to search that array. The rand also has a "nasty" tendency to create the same results repeatedly in an exe. To avoid that, we have to "shuffle the deck" every time. This ensures that all numbers are an equal probability of appearing and not the same set of values (would create a boring game). // Add this to "shuffle the deck" every time to ensure that // different values could occur else the exe produces the...arrow_forward
- Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9arrow_forwardpart a- 2point) for 3 students find the average of a student by asking him how many grades do you have. The answer to this question, determine the size of the array(list of grades) and then ask the user to enter grades(the number of the grades is equal to the size of the array) then calculate the average for each student. Hence, you will calculate 3 averages. to calculate the average, use the array accumulator. Also when you get each grade validate it. validation for grade means that you check whether a grade is between 0 and 100. if the grade is negative or a grade is more than 100 then it is not valid and you have to ask the user to enter a grade again. Part b- 1 point) Find the maximum and minimum grades for each student. Part c- 1 point) Print the sorted list of the grades for each student. example: if grades user entered are: 60 78 98 23 45 then sorted list is:23 45 60 78 98 (Array not vector)arrow_forwardHow is this program written in java?arrow_forward
- Can you write it in Java, add comments Create an application containing an array that stores eight integers. Prompt the user to enter the 8 integers. The application should call five methods that in turn (1) display all the integers, (2) display all the integers in reverse order, (3) display the sum of the integers, (4) display all values less than the calculated average value, and (5) display all values that are higher than the calculated average value. Save the file as ArrayMethodDemoarrow_forwardJAVA I cannot figure this one out no matter what I do I cannot get it to run. Please write it in a student way not in an too advance way. Write an application containing three parallel arrays that hold 10 elements each. The first array hold four-digit student ID numbers, the second array holds first names, and the third array holds the students’ grade point averages. Use dialog boxes to accept a student ID number and display the student’s first name and grade point average. If a match is not found, display an error message that includes the invalid ID number and allow the user to search for a new ID number.arrow_forward
