buffer=null; //free the memory by set as a null but not working????? shows array index out of bound exception for the second time
buffer= new byte[size]; //byte mem alloc
temp2=di.read(buffer,total,size);// read buffer

You cannot set a null value to a primitive array. You could initialize an array size 0 instead...
Uhm, Yes, you can. You cannot assign null to an element of the array but you sure can assign null to the array reference (which is what the OP did).
@OP your problem is that the second argument in your "read" call is the offset into the byte array (that is the first argument) which tells read where to start adding the bytes it reads, and "total" is probably already as large as size making that write beyond the end of the array.
I am working creating a fully encapsulated, homogeneous singly linked data structure. The Listing class and SinglyLinkedList class that are part of the whole application compile fine, but the problem ...
