Explanation / Answer
//this is courseListing.txt .records are space formatted.we can give any spaces between the phrases .if you want ,separated values in between the records put comma(,) between the phrases and change split method regex expression comma(,).i don,t revise total code if you want i revise and i will correct the code test it.
