a)

Create a class called TopographyArray. This class will be used to store data from topovalues.txt. Furthermore, add a private two-dimensional array of type Object.

b)

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 a). The first dimension should be equal to the number of rows in the file, the second to the number of (tab separated) columns.

This exercise involves reading data from a file storing the data in a two dimensional array. implementing methods that perform operations on the data and implementing a command line user interface. You will find the data needed for the visualisation in a file called topovalues.txt. The data rows and columns that are separated by tabs. See an example in the table below Electrode name Angle Radius Amplitude FC4 62.42 0.28822 0.0714 FC6 69.332 0.40823 0.10099 FT8 71.948 0.53192 0.10254 Electrode name Angle Radius Amplitude -90 0.53318 0.034154 CS 0.3999 0.0080936 The first column contains the label names. The position is defined in so called Polar Coordinates that consist of an angle and a radius. The final column contains the amplitude measured at this electrode Polar coordinates are an alternative to the Cartesian Coordinates. They are particularly useful to define positions in concentric circles. This is what we want to do with our electrodes as we approximate the head of a participant using a simple sphere. Cartesian coordinates can be calculated from polar coordinates using the following equations: Xarcos yursing Conversely Cartesian coordinates can be transformed to polar coordinates: aanly.)
