Disk Scheduling Algorithm SSTF, SCAN AND CSCAN Implementations in Java.

Please help with this question: Implement the following functions in java, given the function body is,

The ArrayList contains numbers of track seeks, given as input data read from a file, number of cylinders = 300, and headposition = 50;

Please implement the following functions along with an explanation. Thank you.

public static ArrayList ImplementSSTF(ArrayList list, T numberOfCylinders, T headposition ) { ArrayList searchOrderList = new ArrayList();

return searchOrderList; }

public static ArrayList ImplementSCAN(ArrayList list, T numberOfCylinders, T headposition ) { ArrayList searchOrderList = new ArrayList();

return searchOrderList; }

public static ArrayList ImplementCSCAN(ArrayList list, T numberOfCylinders, T headposition ) { ArrayList searchOrderList = new ArrayList();

return searchOrderList; }

Given Input Data:

21 1 13 46 2 128 45 78 10 212 25 14 34 133 98 251 23 54 32 113
