문제5
An open record store, rs, contains five records with record IDs 1, 2, 3, 4, and 5.
1 . byte[] data = new byte[10];
2 .
3 . for (int i = 1; i <= rs.getNumRecords(); i++)
4 . {
5 . if (rs.getRecordSize(i) > data.length)
6 . data = new byte[rs.getRecordSize(i)];
7 . rs.getRecord(i, data, 0);
8 . System.out.println(new String(data));
9 . }
If record ID 3 is deleted, and the code is run, what is the result?
