2. write two method called findIndex and findLastlndex that search for a number in anarray. they should take an int array and an int as parameters. findIndex should return theindex of the first instance of the number in the array. findLastIndex should return theindex of the last instance of the number in the array. They both should return -1 if thenumber is not found. Do not use any library methods.Sample codeSample outputint al] = {10,50,30,40,50};1%3Dint x = findlndex(a,50);System.out.println(x);int al] = {10,50,30,40,50};4%3Dint x = findLastIndex(a,50);System.out.println(x);int al] = {10,50,30,40,50};-1%3Dint x = findIndex(a,70);System.out.println(x); Homework 11. Use method overriding to write two methods called printArray. On should take an intarray and the other should take a double array. Both should print the array they are givenas an argument.Sample codeSample outputint] x = {9, 3, 5, 1, 5, 10};9 3515 10int] y = {26.12, 72.1, 10, 4.20};26.12 72.1 10.0 4.2%3D

Note:- solved first question. Please repost second question . Logic:- use loop from 0 to lastIndex…

Define an empty array with 4 elements inside the "main" method. The value '-1' from the user to this arrayRecord the numbers entered by the user in order until they arrive. User array with 4 elementsAfter adding, write the required method so that it can continue adding elements. This method will take the array as a parameter, expand the size of the array and return the array variable.will return. Using this method you defined, the user can add elements to the array.make it continue.
Please add comment on each line Thank you very much! Write a static method, getBigWords, that gets a single String parameter and returns an array whose elements are the words in the parameter that contain more than 5 letters. (A word is defined as a contiguous sequence of letters.) EXAMPLE: So, if the String argument passed to the method was "There are 87,000,000 people in Canada", getBigWords would return an array of two elements, "people" and "Canada". ANOTHER EXAMPLE: If the String argument passed to the method was "Send the request to support@turingscraft.com", getBigWords would return an array of three elements, "request", "support" and "turingscraft".
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.
Write a method that calculates and prints both the maximum humidity and maximum temperature values from the abq_weather_cleaned.csv data set. You should write your method in the data Visualization class we have been working on in lecture. Your method should use all of the variables that are already part this program. In particular, you will need to use the data array variable. Your method should return nothing and take no input parameters; it's signature should be void max (). Your print outs should look like this: The max humidity is: 58 The max temperature is: 70
For java. Refer to picture.
Can you write code according to the desired conditions ?
Question is in attatchment. Thanks!
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!".

Submit the code (copy&paste) with a screen shot of the same sample run as below. 1. Write a class ArrayMethods, where the main method asks the user to enter the num ber of inputs and stores them in an array called myList. Create a method printArray that prints the array myList. Create another method copyArray that copies the array using System.arraycopy, and multiplies each element in the copied array by 2, then finally returns the array to the main method. Invoke the printarray again to print the array returned by copyArray. In summary, see below. main method does: asks user for inputs and stores in array. Invoke printArray. Invoke copyArray. Invoke printArray again. printArray: void method, parameters passed is an array, prints an array copyArray: array-returningmethod, parameters passedis an array, copies array, multiplies 2 to each element in the copied array, returnsthe copied array
A method named getUserStringsAndPopulate Array(). This method should keep prompting the user to enter as many strings as the user wants. The user should be able to stop entering strings by entering EXIT. This method should take the strings entered by the user and populate a one-dimensional array of strings with the user input. The string EXIT should NOT be added to the array because it is a special flag that will tell the method to stop prompting the user to enter more strings. This method should return the one-dimensional array of strings populated with user input and should not accept any arguments. 2.b) A method named searchArray() that would accept a one-dimensional array of strings and search the array for the string Winter. The search logic should NOT be case sensitive. If a match is found, this method should print the string in the array followed by a message like " --- Found a match!". Otherwise, the method should not print anything. This method should NOT return anything.…
