Write a java method named addlnto. The method should have two parameters named accumulator of int array type and the second parameter named number. The should have a logic to add the second parameter number into the first parameter accumulator and print out the total sum for 5 different numbers.

An incomplete program named w_pl java, which must include three methods, is provided. You must implement two methods within the program as described below. The third method, which is a main method, is already written in the program and you can use it to test your program. The two methods you mast inplement are: • find method • Signature: public statie vold find(int[] a, int x) • Behavior: • Reccives an array of integers a and an integer x • Performs a linear search on a for x. • If x is in a, print the indexes of the aray slots where x is stored (there may be multiple x's in a) on the screen. • Ifx is not in a, print the message "x does not exist" on the screen. Note that you should not use Java's built-in method. Your program must scan and search the array. • isPrifie method • Signature: public statie boolean isPrefix(String s1, String s2) • Behavior: • Receives two strings sl and s2. Assume that length of sl length of s2. Returns true if sl is a prefix of s2 and returns false…

Write a Java program to make two arrays containing random integer values (You can make these arrays with specific sizes using the below makeRandomArray method). The program should sum these two arrays and prints the resulted array (the array that contains the result of the two arrays summing). The program should also show the maximum element of the resulted array. Your program must define and call the following methods to perform the program as illustrated above: 1- A method int [] makeRandomArray(int size ,int a , int b) that makes and returns an array with specific size. The methods fills this array with random integers in a range [a..b] 2- A method public static int findmax(int x[ ]) that finds the maximum value of a number of x array passed to the method. 3- A method public static void printArray(int x[ ]) that prints the elements of the array x passed to the method. 4- A method public int[ ] sumTwoArrays(int x[ ], int y[ ]) that sums the elements of the two arrays(x and y…

Hello! I need some help with my Java homework. Please use Eclipse Please add comments to the to program so I can understand what the code is doing and learn Create a new Eclipse project named so as to include your name (eg smith15 or jones15). In this project, create a new package with the same name as the project. In this package, write a solution to the exercise noted below. Implement the following method that returns the maximum element in an array: public static <E extends Comparable<E>> E max(E[] list) Write a test program that generates 10 random integers, invokes this method to find the max, and then displays the random integers sorted smallest to largest and then prints the value returned from the method.  Max sure the the last sorted and returned value as the same!

Write a class method named countOccurences that returns the number of times a particular integer occurs in an array of integers. The integer and the array will both be parameters.

Create a class named Problem1, and create a main method, inside  the main method prompt the user to enter a positive integer n. The program (Java) must error check (keep prompting and reading  integers until you get a positive integer n). The program then will create an integer array arr of  size n, and fill up that array with random integers between 1 and 500. - Create a method named getMax, which takes an integer array arr and returns an integer, the method should find the maximum value in the integer array arr.  - Create a method named getMin, which takes an integer array arr and returns an integer, the method should find the minimum value in the integer array arr. - Create a method named sumValues, which takes an integer array arr and returns an integer, the method should find the sum of all values in the integer array arr. - Create a method named getAverage, which takes an integer array arr and returns a double, the method should find the average of all values in the integer array…

In Java: Write a method that multiplies all elements in the array by 3 and returns it to the main method.

Problem: Write a method that will determine whether a given value can be made given an array of coin values. For example, each value in the array represents a coin with that value. An array with [1, 2, 3] represents 3 coins with the values, 1, 2, and 3. Determine whether or not these values can be used to make a desired value. The coins in the array are infinite and can only be used as many times as needed. Return true if the value can be made and false otherwise. Dynamic Programming would be handy for this problem. Data: An array containing 0 or more coin values and an amount. Output: Return true or false. Sample Data ( 1, 2, 3, 12, 5 ), 3 ( 4, 15, 16, 17, 1 ), 21 ( 1 ), 5 ( 3 ), 7 Sample Output true true true false

You are given an array of n integers. Write a java method that splitsthe numbers of the array into two equal groups so that the GCD of all numbers in the second group is equal to one and the GCD of all numbers in the first group is not one. After splitting the numbers display the resulting groups as shown in the sample run below. Note: 1. The array has even size. 2. All elements of the array are less than 100. You are not allowed to define new arrays. 3. 4. You are not allowed to definenew methods or use methods from java libraries. Sample run of the method: Inputarray: (6,7,9,4,3,2} Output Group two: (7,9,3} Group one: (2,4,6} I Ignore Order of numbers. Order is not important //Ignore Order of numbers. Order is not important

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…
