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.

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.

Based on the information in the screenshots, please answer the following question below. The language used is Java and please provide the code for it with the explanation. Create a testing class named “PlanTest”. Under this class, there needs to be another static method besides the main method: You will need to create a static method named “prerequisiteGenerator” under “PlanTest”, which return a random 2D array containing prerequisite pairs (e.g., {{1, 3}, {2, 3}, {4, 2}}). The value range of a random integer is [0, 10] (inclusive). This method will accept an integer parameter, which specifies the length of the returned array: int[][] pre = prerequisiteGenerator(3); // possibly {{1, 3}, {2, 3}, {4, 2}} Under the main method, you will need to use prerequisiteGenerator to generate random prerequisite pair lists, and perform tests on plan method at least three examples by printing proper messages. Given 4 courses and prerequisites as [[1,0], [2,0], [3,1]] It is possible to take all…

Show your code and console with the exact sample run. Thankyou
