Write a static called printAll in a class with Array tools. Make this method print all the elements in the String array. Return the size of that array. Write in Java and use test case 1 as a reference.

I need to have a main method in a Tester class that will: Fill an array of type Vehicle[] of size NUM_VEHICLES with Vehicle objects. You need to generate a random number between 0 and 2. If the number is 0, add a Vehicle to the array. 1, add a Car, 2, add a Boat. The Vehicle/Car/Boat that you add must be initialized with a random efficiency between 0 and 100.0. Do this until you have added NUM_VEHICLES objects to the array How do I write it so that the array generates random numbers 0 through 2 (inclusive) and how would I then correlate those numbers to a different class object?

Write the Java method averageOfDoubles that is passed an array of double values, and returns the average of the array values.You can assume the array length is a positive integer.

This is in Java. The assignement is to create a class. I am confused on how to write de code for an array that is up to 5. Also I am confused regarding how to meet the requirements of the constructor. This is what I have. public class InventoryOnShelf { //fields private int[] itemOnShelfList []; private int size; public InventoryOnShelf() { }

Could i get help with this java program where you have to write a static method which reverses an integer array. The array will be a parameter to the method. Put the method in a Test class Your method would be called as follows int [] num = {2, 3, 5, 7, 11, 13, 17}; // Call the method to reverse the array Test.reverse(num); Your method should not print anything. It will be called by the following program: import java.util.Scanner; public class Main { public static void main(String [] args) { // Create a scanner object Scanner in = new Scanner(System.in); System.out.print("How many numbers: "); int len = in.nextInt(); int [] num = new int[len]; System.out.print("Enter " + len + " numbers: "); for(int i = 0; i < num.length; i++) num[i] = in.nextInt(); Test.reverse(num); System.out.print("The numbers reversed are:"); for(int i = 0; i < num.length; i++) System.out.print(" " + num[i]); System.out.println(); } } This program will read in the array and use your method to reverse the...

Can you help me fix my code in Java, please? I am stuck to keep going. Thank you

Write a java method called switchThem that accepts two integer arrays as parameters and switches the contents of the arrays. Take into account that the arrays may be of different sizes.

Needs to be written in java: Write a program with a main() method that asks the user to input an integer array of 10 elements.Next, create three methods described below. From inside your main() method, call each of thethree methods described below and print out the results of the methods 2, 3, which return values.1. printReverse() - a method that receives an array of integers, then reverses the elements ofthe array and prints out all the elements from inside the method. Print all in one lineseparated by commas (see sample output below).2. getLargest() – a method that receives an array of integers, then returns the largest integervalue in the array. (print result from main())3. computeTwice()- a method that receives the previously reversed array of integers, thenreturns an array of integers which doubles the value of each number in the array (see thesample output below). (print result from main())Sample output:Enter a number:22Enter a number:34Enter a number:21Enter a number:35Enter a...

Write a program to test your implementation by reading data related to 50 Car objects and store them in an array ARR of Car. Your program should include:a. A method Search() that takes as parameters an array of Car objects ARR and a Car object C. This method should return true if C is inside ARR, false otherwise. b. A method findCylinders that takes as parameters an array of Car objects ARR and number of cylinder engine N. It should display all the cars that have N cylinder engine.

Needs to be written in java and completed using "for loops" or "nested for loops" and in one program just seperate methods: Write a program that calls these three methods. method 1 should print: 5 4 3 2 1 4 3 2 1 3 2 1 2 1 1 method 2 should print: 1 2 3 4 5 1 2 3 4 1 2 3 1 2 1 method 3 should create and array and store 10 multiples of 5 and print it out. Use for loop to generate the multiples and then print them out using a second for loop.

Needs to br written in java: printPattern (int a) – A void method which takes user input as a parameter and generates 5 multiples of the input and stores the multiples in the array and finally prints the numbers in the following pattern (See expected output)Note: Use the array to print the numbers Enter a number : 4 Multiples of 4 are stored in an array – [4,8,12,16,20] 4 4 8 4 8 12 4 8 12 16 4 8 12 16 20

Without using any pre-defined method. Don't copy from internet Two array is given and you check whether these array is equal or not in java. Without using any pre-defined method
