Using JDBC driver in Java code

Locate JDBC jar file and install it into local maven repository:

mvn install:install-file -Dfile=<trino-jdbc-*.jar> -DgroupId=io.trino -DartifactId=trino-jdbc -Dversion=<trino-jdbc-version> -Dpackaging=jar -DgeneratePom=true

Download and unpack sample java code connecting to Trino using JDBC. See included README.md for details and examples.
