- Write a java program: Question 1 Write a program that allows the user to enter name and grade until "QUIT" is entered for name. The grade should be a number between 0 and 100. If the user input of a grade is not in this range, you should ask the user to re-input the grade. Store all the names in an array called names, and all the grades in an array called grades. Print out all the names and the corresponding grades. For Example, Input Enter name: Alice Enter grade: 90 Enter name: Bob Enter grade: 80 QUIT Expected output Name: Alice, Grade: 90 Name: Bob, Grade: 80QUESTION 1 Write a Java program to do the following task: Input n from user. Create an array to store n double values. Initialize it with n random numbers ranging from 10.0 to 100.0 (both included). Pass the array to a method that calculates the sum of those n numbers. Print the sum in the method.BY Dr.java : Using methods and arrays, write a program that Creates an array A of size 100 integers. Enter a set of values to fill the array. The values should be within the range 50 to 65 inclusive. If an incorrect value has been entered then the program should display a message asking the user to re-enter the value again. Find the average of the values that are divisible by 7.
- 4. Given an integer array of size 10, write a Java program to prompt the user to enter an integer value num and in the output print all numbers in the array greater than num. If no such number is present then print the message "No Results Found." in the output. Given Array: {12,67,45,89,94,56,78, 34, 47, 63}Use java language Write a java program that will accept 10 decimal numbers and save it on array. After the input of 10 decimal numbers, compute and display the total and average of the array.Here you go 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..
- 2. Write a program to create a 2-D array of size 3 X 3. The user enters the data. Then, display the data of the array. This is just to make sure you understand 2-D arrays. Sum the columns of the array. Print this out. Sum the rows of the array. Print that out. Find the highest number in the array. Make sure Java standards and good formatting are followed.Write a program that does the following: • Reads an integer from the user that represents the number of the students in a class. • Reads the scores of the students from the user and stores them in an array. • Calculates and prints the average of the students with a passing grade (above or equal to 60). Hints: Assume that the scores of the students are integers between 0 and 100 (inclusive) • Assume that there is at least one student in the class with a passing grade. Using java Sample run 1: Enter the number of students in the class: 3 Enter the scores of 3 students: 90 80 40 The average of the students with a passing grade is 85.0 Sample run 2: Enter the number of students in the class: 5 Enter the scores of 5 students: 90 80 40 60 70 The average of the students with a passing grade is 75.0Write a java program to perform the following operations on an array 1. populate an array with 10 integers between -100 and 100 (not hard-coded) create a menu after populating the array to enable the user to select an option to perform 2. find and display the negative numbers in the array 4. display all odd numbers in the array 5. display all numbers in the array 6. display all numbers in the array in reverse order 7. display all 5 multiples 8. display the count of the negative numbers in the array 10 display the count of the positive numbers in the array submit the source code, and the output (make sure to label all outputs)
- For Beginners Java: Write a program that ask the user to enter a list of positive scores until the user enters a negative score to terminate the input. You need to store these scores in an array. You can assume the maximum number of scores the user may enter is 50. However, you need to keep track of the actual number of scores entered. Write 2 methods: 1. calculateAverage(): this method takes the list of scores and return the average score. 2. countPerfectScores(): this method takes the list of scores and return the number of perfect scores (100). The main program reads the input and calls these methods and print the results. Please make sure you write a comment line to document what your method does.Create a java program that generates elements (randomly from 10 – 50) of a 2-dimensional array (5x5) using the Random Class then perform the following: 1) Output the array elements 2) Output the sum of prime numbers in the array 3) 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.Write a program to store an array of integer random numbers. Program should find out from the user how many numbers to store. It should then generate and store that many random integers (the random numbers must be between 1 and 999 inclusive). The program should then determine the smallest number, the largest number, and the average of all the numbers stored in the array. Finally, it should print out all the numbers on the screen, five numbers to a line with spaces in between. Once the contents of the array have been printed to screen, display the smallest number, largest number, and average determined previously ensuring that the program design in modular. Explain whether the static variables and methods can can be used and why. The Random class of Java library (java.util.Random) implements a random number generator. To generate random numbers, construct an object of q the class Random, and then use the method nextInt(n) which returns a number between 0 (inclusive) and n (exclusive).…
