a)

create a class called TAarray, this will store the values of the topV.txt

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.

you will need to create a constructor to add to the class. The constructor should receive a string as parameter that contains the name of the file.

After this you should make a method called readTArray. The purpose of this is to read the data from the file into a two dimensional array which you created in a). The dimension should be the same as the number of rows in the file, the second should be the number of separated columns.

c)

add these functions

public String getT{

}

for this function, you should Construct a single string that contains all the electrode labels from the file in one line. Return this string.

public double getAngle(String label){

}

for this 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){

}

for this 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){

}

you have to 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){

}

finally, for this Get the label closest to the angle and radius provided as parameter. Return this label as a String.
