Consider a 2D int-array that contains the brightness values of the pixels in an image. Write a method named getBrightestRow that takes a 2D array (i.e., pixels of an image) as the input parameter and returns the brightest row number in the array. The brightness value of a row is the average of the brightness values given in the pixels of the row. For example, in the 2D array given below, the method will return 1.

- The editTemperatures() method takes in two parameters: integer array tempData and integer numMore. Complete editTemperatures() to create a new array called arrayCopy with the same elements as tempData, and the size increased by numMore. Ex: If the input is: 10 48 49 18 3 then the output is: 10 48 49 18 0 0 0 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 Scannerscnr=newScanner(System.in); int[] degreesFahrenheit=newint[4]; intinput; inti; for (i=0; i<degreesFahrenheit.length; ++i) { degreesFahrenheit[i] =scnr.nextInt(); } // Read number of values to increase array size by input=scnr.nextInt(); degreesFahrenheit=editTemperatures(degreesFahrenheit, input); for (i=0; i<degreesFahrenheit.length; ++i) { System.out.print(degreesFahrenheit[i] +" "); } } }Write a program that creates a 2-D array initialized with test data . Use any primitive type of data EXCEPT int (Integer). The program should have all methods in the problem. getTotal - This method should accept a two-dimensional array as its argument and return the total of all the values in the array. getAverage - This method should accept a two-dimensional array as its argument and return the average of all the values in the array. getRowTotal. - This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. getColumnTotal - This method should accept a two-dimensional array as its First argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the total of the values in the specified column.…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…
- 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); } }This code is in java.Your friend’s photo editing software has stopped working so you volunteer to help. She wants all the pictures reversed in the horizontal direction along the y-axis so that items on the left side of the picture are now on the right side, and vice versa. Pictures are stored as 2-D arrays, where each “pixel” stores a single brightness value. In other words, you need a method that will take a 2-D array and reverse its columns so that the first becomes the last, the second becomes the second to last, and so on. Given the following starter code, write the method to help your friend.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 =…

INPUT: The first line of input contains an integer a. The Second Line of input containes and integer b. OUTPUT: Print the result which is the sum of a and b.In java, Write a method checks if a given matrix is a unit matrix. An N x N unit matrix is a matrix of N rows and N columns where all the diagonal elements are ‘1’s and all the remaining elements are ‘0’s. The method should take a 2D array of integers as argument and return a Boolean which is true/false depending on whether the matrix corresponding to the 2D array is a unit matrix or not. Test the method in the ‘main’ method. For problems asking for 'methods', you need to write the method, and the 'main' method which is used as a 'driver' to test the given method.
- Image one is my file or you can create ur own file as long as it's similar to mine. image 2 is my program I want to write a 4th method(method 4) and the spec is: A method to count the occurrences of each value in an array takes one parameter, an array of integers returns an array containing the number of times each value occurs in the parameter array. Also should call method 3 from method 4Hint: The general idea of this method is using an array with length maxVal+1(maxVal should get from method 3 already) to save the occurrences of each number. For example, if number 44 occurs 3 times in the file, your array should have a value 3 stored at index 44.Develop a complete Java application. In the main method of the application, create a jagged 2D array of type int having six rows (i.e. an array having six arrays). The number of elements in a particular row must be equal to the corresponding digit of your own roll number. For example, if somebody's roll number is 141257, then the resultant array would look like: 3 4 6. 7 8. 9. 10 11 12 13 14 15 16 17 18 19 20 Next, you must use nested loops to initialize the elements of the 2D array with the value of a counter that is incremented by 1 during each iteration of the inner loop, as shown in the above example. Finally, use nested loops to display the values of all the elements stored in the array. Each row must be printed in a separate line. For example, following would be the output for the above array. 1 2345 6. 78 9 10 11 12 13 14 15 16 17 18 19 20Write a method that takes a rectangular two-dimensional array of type int. The method returns true if the sum of the even elements of the parameter array are larger than the sum of the odd elements, otherwise the method returns false. public static boolean sum(int[]0 in) Taken array Result 1 -3 17 5 -2 30 true 1 3 -1 -1 -3 -4 7 -1 10 false -1 3 -4 15
