one method only

i need to modify one last method to complete my college project but i am unable to do it properly, for database programmers with any sort of experience this should be a very simple job attached is the project description that states the conditions that need to be adhered to. the method i am struggling with is searchtable() that searches a table based on the clustering index if the clustering index is the primary key i expect the method to search using a sparse index while if the clustering index is not primary key i expect an dense index to be created on the primary key then a sparse index to be created on that 1st level index then executing the search. Note i do not expect you to do the entire assignment only updating the searchInTable() method at line 271. Project description is in the 2nd file. languages needed are only java.
