Question

Write a Java program to work with two arrays and perform operations on them.
Your program should have 2 methods:
int[] union (int[] al, int[] a2): takes two integer arrays and returns a new
integer array consisting of all ints that appear in either a1 or a2. The returned array
should be appropriately sized and should contain any duplicate ints since everything
from both a1 and a2 should be in there. The returned array should not have any empty
spots and should be sorted numerically.
●
●
int[] intersection (int[] al, int[] a2): takes two integer arrays and returns a
new integer array consisting of all ints that appear in both a1 and a2. The returned array
should be appropriately sized and sorted numerically, and it should not contain any
duplicate ints or empty spots.
For example, when a1 = {1,2,3,4,5} and a2 {1,5,6,7,8}, union (al, a2) will return
{1,1,2,3,4,5,5,6,7,8} and intersection (al, a2) will return {1,5}.
=
Provide the following menu using a do..while loop in the main method to the user.
1. Union
2. Intersection
3. Exit
Before the menu pops up for the user, the main method should collect the input for the 2
arrays and create the arrays. After the user picks a menu choice, the main method should call
the appropriate method to do the work requested. Since these methods return new arrays to
the caller, the printing of the output of the new array should also be done by the main method.

In java i have some code for a method that finds the index of an integer that is passed in thet int is (target) the method also has the array called (array) and the first and last element of the array. also for this method to work the array has to be in descending order "static int find(int [] array, int first, int last, int target)" thats the method with all the variables that are passed to it my guess is that the first if statement just will have a short line that is "return -1;" because since the array has to be in descending order the first element cant be greater then the last element in the array but im confused on the rest because i cant find a way to make them one line codes with the conditions that i have to meet in the comments any help would be aprreaciated
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…

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.

Displays array data as a histogram – graphically by plotting each numeric value as a bar of asterisks (*) as shown in the example diagram. This is somehow similar to Lab11 Sample output 9 Enter the size of array: Enter 9 integer values: 10 19 14 Minimum -o Maximum - 19 = 68 Sum Average = 7.55 ========== Histogram: - ------= Element Ualue Hintogran 19 ***** ***** 11
Write a Java method (do not write a class, only the method) with the following signature: Return type: void Parameters: 2D integer array Name: printDiagonal Implement the method code that will print out the values of the 2D array along the Diagonal from left to right. For example, if the array had the following values: 56 78 98 21 33 55 98 44 11 The method should print to the console: 56,33,11 The above 2D array example is only given for you to understand the problem Do not hard code the values in your solution or assume the array is the same as the given data. Your method should work for all 2D integer arrays.

Create a Java program that will perform the following statements.Perform the following items in a continuous manner. The code solution for the next item will be basedon the code performed on the previous item.1. Create an ArrayList named “apostles” and add the following names to it: Juan, Pedro, Lucas,Judas, Mateo, Marcos and Simon.2. Print the size of the ArrayList to the standard output before and after adding the names.3. Use two methods to print the names in standard output.a. Using For loopb. Using Iterator4. Add the name “Philip” at the end, and add the name “Thomas” between the two names “Juan”and “Pedro”.5. Remove the name “Judas” using its index position.6. Search the names “Marcos”, “James” and “Judas” in the ArrayList “apostles”This part will display the following:Does “apostles” contains Marcos? _______ (it will return a Boolean result)Does “apostles” contains James? _______Does “apostles” contains Judas? _______7.

java a. A method named contains exists that takes an array of Strings and a single String, in that order, as arguments and returns a boolean value that is true if the array contains the given String. Assume that an array of Strings named names is already declared and initialized. Call the method to see if the array contains the name "Fred", and save the result in a new variable named fredIsHere. b. Given a method named printMessage that takes a String argument and returns nothing, call the method to print out "I love Java!".
