an ArrayList of ArrayLists

Add a new method to ArrayTools with filter. Make this method accept a String array. Change all the Strings that are longer than 5 characters to uppercase.   Write in Java and use test cases 1 & 2 as a result.

Write a static method blur(double[][]picture) that you could use on a part of a picture file to obscure a detail such as a person’s face or a license plate number. This method computes the weighted averages of the values in picture and returns them in a new two-dimensional array. To find a weighted average of a group of numbers, you count some of them more than others. Thus, you multiply each item by its weight, add these products together, and divide the result by the sum of the weights. For each element in picture, compute the weighted average of the element and its immediate neighbors. Store the result in a new two dimensional array in the same position that the element occupies in picture. This new array is the one the method returns. The neighbors of an element in picture can be above, below, to the left of, and to the right of it, either vertically, horizontally, or diagonally. So each weighted average in the new array will be a combination of up to nine values from the array…

The input to this method is supposedly an ArrayList of integers    that ranges from 1 to 100, however this is not exactly the case.    Sometimes, there will be gaps in the range for example, the range    could be: [1 2 ... 7 8 ... 99 100], with missing ranges in between.    Find all the missing numbers from the range, add them to an ArrayList,    return the ArrayList.------------------------ Below is my code that is failing. It is returning the correct missing numbers but is not going passed the last number  from the array. so [4,5,14,16,23,76,89] It is placing all of the missing numbers up to 88 when it should be going to 100 The solution should only return the missing numbers from 1-100. The original numbers from the given array should not be included in the return. How can I only return the missing numbers?  ------------------------ public ArrayList<Integer> solution(ArrayList<Integer> nums) {ArrayList<Integer> result = new ArrayList<Integer>();int count =…

Four integers are read from input and stored into the array arrayToModify. Write a static method resetFirstValue() that takes an integer array parameter and replaces the first element with 1. Ex: If the input is 55 45 70 65, then the output is: Original array: 55 45 70 65 Changed array: 1 45 70 65 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35     Scannerscnr=newScanner(System.in); finalintNUM_ELEM=4; int[] arrayToModify=newint[NUM_ELEM]; inti; intuserNum;   for (i=0; i<arrayToModify.length; ++i) { arrayToModify[i] =scnr.nextInt(); }   System.out.print("Original array: "); printArr(arrayToModify);   resetFirstValue(arrayToModify);   System.out.print("Changed array: "); printArr(arrayToModify); } }

The WalkingBoard class represents a board with a figure standing on position x,y. Each position also has a value associated with it. Initialise the board in two different ways: either make it size×size or use the given dimensions and initial values. About the second way: The rows may not be uniform: they may have differing numbers of columns in them. Don’t simply take the argument array: create its copy in the field. All values are set to BASE_TILE_SCORE, or to the given value if that’s bigger. Operations. getPosition: returns the values of x and y in an array. getTile: returns the value of the of the board position. Let this condition be checked by the helper method isValidPosition. If it is an invalid position, throw an IllegalArgumentException. getTiles: returns the values of all the board positions. Don’t let the field contents be accessed from the caller: create and return an exact copy of the structure. getXStep and getYStep: helper methods, they indicate how far (-1,…

Which of the following statements about ArrayLists is false? A running program can determine the size of an ArrayList. O You can get an item from a specified index in an ArrayList. O You can add a new item to the end of an ArrayList. O Once an ArrayList is created, its size cannot be changed.

Draw a square with a Pentagram hole! The 3×3 square extends from −0.7 to 2.3 on the X axis and from −0.3 to 2.7 on the Y axis. Keep the X and Y arrays named xp and yp, respectively. The template code it's below. I need help with the ellipsis. import matplotlib.pyplot as plt xp = [0, 0.81, 1.62, 1.31, 2.12, 1.12, 0.81, 0.5, -0.5, 0.31, 0] + [None] +[..., ..., ..., ..., ...] yp = [0, 0.59, 0, 0.95, 1.54, 1.54, 2.49, 1.54, 1.54, 0.95, 0] + [None] + [..., ..., ..., ..., ...] plt.axis("equal") plt.axis("off") plt.fill(xp, yp) plt.show() Expected result:

Write a public static method named allLessThanMean that will take an ArrayList<Integer> as an argument. This method will return an ArrayList<Integer>. When called and passed anArrayList, this method will return an ArrayList containing all the elements in the argument ArrayList that are less than the average of all the values in the argument ArrayList. The values in the returned ArrayList must be in the same order as they are in the argument ArrayList. Here are some examples: Example 1 Given: ArrayList<Integer> myList = new ArrayList<Integer>(); with these values {1, 2, 3, 4, 5}; allLessThanMean(myList) should return an ArrayList<Integer> with these values {1, 2} Example 2 Given: ArrayList<Integer> myList = new ArrayList<Integer>(); with these values {3, 7, 6, 2, 9, 0, 4, 8}; allLessThanMean(myList) should return an ArrayList<Integer> with these values {3, 2, 0, 4} Example 3 Given: ArrayList<Integer> myList = new…
