+ DESCRIPTION 
+ The code sample shows how to use the JDBC driver to establish a connection
+ to the Autonomous Database (ADB) using access token 
+ issued by the OCI Identity service. 
+
+ Step 1: Enter the DB_URL to pointing to your Autonomous Database (ADB)
+ Step 2: Make sure to have either 21.4.0.0.1 or 19.13.0.0.1 JDBC driver 
+ in the classpath. 
+ Step 3: Compile and run the sample JDBCDBTokenSample
+
+ NOTES
+ Use JDK8 and above
