Use java. Exercise 2 - NumbersCreate a new class called Numbers that contains a method called nextLargest. Thismethod should accept an array of numbers and an integer, and output the next bigger numberthat is found in the array or the maximum possible int value, if none are larger. Using thismethod in main to iterate through all values in a predefined array, and output the next largestnumber.For example, if the array is{78, 22, 56, 99, 12, 14, 17, 15, 1, 144, 37, 23, 47, 88, 3, 19}the output should look like the following (? is a placeholder):78: 8822: 2356: 7899: 14412: 1414: 1517: 1915: 171: 3144: 214748364737: 4723: 3747: 5688: 993: 1219: 22NOTE 1: If there is no bigger number in the sequence, just display the value ofInteger.MAX_VALUE. This is a constant this automatically defined as a static variable insidethe Integer class.NOTE 2: ? should be replaced with the appropriate number

CODe full java. In this assignment, you will implement a class called ArrayAndArrayList. This class includessome interesting methods for working with Arrays and ArrayLists.For example, the ArrayAndArrayList class has a “findMax” method which finds and returns themax number in a given array. For a defined array: int[] array = {1, 3, 5, 7, 9}, callingfindMax(array) will return 9.There are 4 methods that need to be implemented in the ArrayAndArrayList class:● howMany(int[] array, int element) - Counts the number of occurrences of the givenelement in the given array.● findMax(int[] array) - Finds the max number in the given array.● maxArray(int[] array) - Keeps track of every occurrence of the max number in the givenarray.● swapZero(int[] array) - Puts all of the zeros in the given array, at the end of the givenarray.Each method has been defined for you, but without the code.

The Utilities class contains three independent static methods and contains no fields (none should be added).The Utilities class contains the following 3 static methods that you must implement:1. QWERTY – If the argument is null, the length is anything other than 6, or if the element values are outside the inclusive boundof 1 to 7 throw the IllegalArgumentException with the message "Invalid parameter". Otherwise return a char array that hasinput[0] instances of 'Q', followed by input[1] instance of 'W', ....followed by input[5] instances of 'Y'. The length ofthe returned array should be the exact size needed to accommodate all the letters (no smaller or larger).2. turnTo1D – You can assume that the parameter array has at least 1 row and all rows are int array (might be an empty int array)and the parameter delta is a positive integer. The method returns a 1D array (possibly empty array) with all the values inarray that are in the range of the inclusive bound [value – delta to value +…
java In this task, you need to write 2 overloaded methods findMax() that will find a maximum number in the array. First version should work with array of integers (int[]) and return int, and second method should work with an array of doubles (double[]) and return double as a result. Methods must have the same name and different parameters.
Define an array to be a 121 array if all elements are either 1 or 2 and it begins with one or more 1s followed by a one or more 2s and then ends with the same number of 1s that it begins with. Write a method named is121Array that returns 1 if its array argument is a 121 array, otherwise, it returns 0. There is one additional requirement. You should return 0 as soon as it is known that the array is not a 121 array; continuing to analyze the array would be a waste of CPU cycles. If you are programming in Java or C#, the function signature isint is121Array(int[ ] a) If you are programming in C or C++, the function signature isint is121Array(int a[ ], int len) where len is the number of elements in the array a. Examples a is then function returns reason {1, 2, 1} 1 because the same number of 1s are at the beginning and end of the array and there is at least one 2 in between them. {1, 1, 2, 2, 2, 1, 1} 1 because the same number of 1s are at the beginning and end of…

(a)Implement all the classes. The formula for calculating salary for each class is shown below: For the Employee class, salary = basic salary + allowance For the Manager class , salary = basic salary + allowance + travel claims For the Clerk class , salary = basic salary + allowance + overtime pay,where overtime pay = overtime hours x overtime rate. Set overtime rate as RM3.50. Write a client program that creates an array named empArray that stores an object of an Employee,a Manager and a Clerk.In your program, include a method called printElements() that takes an array as parameter and prints the type of employee, the object’s data field values (by invoking thetoString() method) and the monthly salary.

Read the quistion entirely before ansewring the code should compile and run Create a java class called Question2, and inside this class implement a non static public method called void printLargestInEachRow( int [][] ), which takes as a formal parameter a two-dimensional array of int type, and prints the largest element in each row of the array.Also, create a main method Inside class Question2. In the main method, declare a two-dimensional array of size 4x4, and initialize it with the following values:{[1,2,3,14],[15,13,12,10],[33,35,23,22],[14,18,28,7] }Then, call the method printLargestInEachRow and pass the initialized array as an actual parameter to printLargestInEachRow.
1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…
Write a RainFall class that stores the total rainfall for each of 12 months into an array of double s. The program should have methods that return the following: • the total rainfall for the year • the average monthly rainfall • the month with the most rain • the month with the least rain • Test the RainFall class by writing a tester class, RainFallDemo , to produce the outputs similar to the sample execution below. For the rainfall values, you must get them from the user’s input as double values in the tester class. For the class RainFall you must write standard Java Documentation for the whole class on the top, and for every method. Input Validation: Do not accept negative numbers for monthly rainfall figures. If a value is negative, ask the user to re-enter the input.
Java : OverviewYou must write a class with which we can generate user identities for employees in a company. The purpose is for you to learn how to use arrays and ArrayList to store multiple values of the same type. TaskIn many workplaces, employees are assigned a username to be able to log in to their computers. One method of generating these usernames is to take the first three letters of the first name and the first three letters of the last name and let them together form the username. A person with the name Sven Andersson then gets the username sveand (only lowercase letters). Your task is to write a class named Usernames that should contain a static method named create, which creates a username as above. The method should take an array of type String as an argument, and return an ArrayList containing a string for each generated username. The array sent as an argument to the method is assumed to contain strings with the employees' names according to the form "first name last…
