Assume that you have an Oracle database schema named ecommerce, which is hosted on the $192\mathrm{.}168\mathrm{.}88\mathrm{.}30$ server that uses $1523$ as DB port. The ecommerce DB has several tables, including the authors table. The Oracle Schema DB user is $$ecommerce$,$ whereas the DB password is $$ptuk$.$ Part $1$: Code Complete The class OracleConnection is not fully written, you need to complete the missing parts $-$whenever necessary$-$ so that you convert it into functioning code snippets. Paste or upload the resulting new Java file as part of your answer below. The file should contain no errors $($errors are typically penalized$)//$ Write down the necessary imports in separate statements! $//$ All the missing parts should be completed. $//$ You cannot change the class structure! $............................................................$ public class OracleConnection $\{$ static final String DB$\_$URL $="............................................................................................................"$; static final String USER $="....................."$; static final String PASS $="$pwd$"$; public static Connection getOracleConnection
