Exercise 2A [2%] Create a class call TopographyArray. This class will be used to store data from topoValues.txt. Furthermore, add a private two-dimensional array of type Object. Exercise 2B: Reading the data [4%] Add a constructor to the class. The constructor should receive a String as parameter that contains the name of the file. Add a method called readTopographyArray. This method should read the data from the file into the two-dimensional array you created in 2A. The first dimension should be equal to the number of rows in the file, the second to the number of (tab separated) columns. Exercise 2C Accessing the data [7%] Add the following functions to access the data. See the comments in the code below regarding the functionality that should be provided by your implementation. public String get Topography() { Construct a single string that contains all the electrode labels from the file in one line. Return this string. } public double getAngle(String label){ Get the angle of the electrode position defined by the label provided as a parameter. Make sure you do not take white space surrounding the label or capitalisation of the letters into account. */ public double getRadius (String label){ Get the radius of the electrode position defined by the label provided as a parameter. Make sure you do not take white space surrounding the label or capitalisation of the letters into account. public double getAmplitude (String label){ Get the amplitude at the electrode position defined by the label provided as a parameter. Make sure you do not take white space surrounding the label or capitalisation of the letters into account. / public String getClosestLabel (double angle, double radius) { Get the label closest to the angle and radius provided as parameter. Return this label as a string. Exercise 2D: User interaction (7%) Now create a class called MainExercise2 with a main() method. Add code to the main() method that will prompt the user to enter a 1 (numeric one) to print the electrode labels, a label to retrieve the corresponding angle, radius and amplitude, an angle and radius to retrieve the closest label or quit to quit. This prompt should query the user for new inputs until the user enters "quit". You should verify that the input is a valid and the choice of output should be derived from the input. An example of the output could look like this: Please enter: . 1 to print electrode labels . a label to retrieve angle radius and amplitude of this electrode . an angle/radius pair to retrieve the closest label . quit to quit. 12 Invalid input!
