Write a program called GradesAverage, which prompts user for the number of students, reads it from the keyboard, and saves it in an int variable called numStudents. It then prompts user for the grades of each of the students and saves them in an int array called grades. Your program shall check that the grade is between 0 and 100.

Write a java program called GradesAverage, which prompts user for the number of students, reads it from the keyboard, and saves it in an int variable called numStudents. It then prompts user for the grades of each of the students and saves them in an int array called grades. Your program shall check that the grade is between 0 and 100. A sample session is as follow: Enter the number of students: 3 Enter the grade for student 1: 55 Enter the grade for student 2: 108 Invalid grade, try again... Enter the grade for student 2: 56 Enter the grade for student 3: 57 The average is 56.0

Write a class called AnalyzeNumbers which asks the user to enter the number of inputs and stores them in array, then prints the total numbers greater than the first inputted number: please show your code and console. Also refer to the pic.
Write a program that prompts the user for an integer, then asks user to enter that many integer value. Store these values in an integer array and print the array. Reverse the array elements so that first element become the last element, the second element become the second to last element, and so on, with the old last element now first. Do not just reverse the order in which they are printed; actually, change the way they are stored in the array. Try not to create a second array; just rearrange the elements within the array you have. (Hints; Swap elements that need to change place.) When the elements have been reversed, Print the array again.
Write a Java program named Findletter that asks the user to enter 10 letters and store them in an array. Then it should ask the user to enter a letter (char value) to search for it. Then, if the entered letter is found, the program should display the message "The letter is in the array", otherwise it should display the message "The letter is not in the array".
Write a java program that:1. Prompts the user to enter an integer representing the size of an array of integers2. Fills the array with integers from the user3. Creates an array of integers to hold the differences between two consecutive elements, fills it accordingly and displays itExample: In the below sample run, the array is of size 7 and is filled using values entered by the user with the below integers. The array of differences contains -10 which is (22 – 32), 2 which is (32 – 30), -18 which is (30 – 48) and so forth.Sample Run:Enter the size of the array: 7Enter 7 integers: 22 32 30 48 54 26 21Differences: -10 2 -18 -6 28 5
Write a program that accepts two integer values, called "arraySize" and "multiplier", as user input. Create an array of integers with arraySize elements. Set each array element to the value i*multiplier, where i is the element's index. Next create two functions, called PrintForward() and PrintBackward(), that each accept two parameters: (a) the array to print, (b) the size of the array. The PrintForward() function should print each integer in the array, beginning with index 0. The PrintBackward() function should print the array in reverse order, beginning with the last element in the array and concluding with the element at index 0. As output, print the array once forward and once backward.
Write a program called FiveLetterWords that: prints your name followed by three asterisks; reads the words in a text file into a String array, where each array entry contains a word; prints the number of words in the file; counts and prints the number of five-letter words; prints all of the five-letter words starting with a vowel (that is, 'a', 'e', 'i', 'o', or 'u'); finds and prints the alphabetically first five-letter word and the alphabetically last five-letter word. tale.txt file content : it was the best of times it was the worst of timesit was the age of wisdom it was the age of foolishnessit was the epoch of belief it was the epoch of incredulityit was the season of light it was the season of darknessit was the spring of hope it was the winter of despair
Write a program which allow user to enter a number that represents repetition. Then, the userwill need to enter any random decimal number based on the number of repetition. The numbersshould be stored in a single dimensional array. Lastly, the program will display the averageof these numbers and count how many numbers that above the average.
Write a Java program to generate random integer values between 5 and 20 to fill a single dimensional integer array of size 10. Pass the array to a method named computeArray that returns an array. In this method, if a number is odd then multiply it by 5 and if it is even then divide it 3 and place them in another array. Display the two arrays and their total by invoking a method named displayArray. Here is a sample run of this program (with an array of 4 elements): The generated array 12 17 4 20 The output X Y 12 4 17 85 4 1 20 6 ___ ___ Total=53 96
