below is the code
public class T4DB2Connect {
public static void main(String[] args) {


try {
// load the DB2 Driver
System.out.prin tln("1" );
Class.forName(" COM.ibm.db2os39 0.sqlj.jdbc.DB2 SQLJDriver");
// establish a connection to DB2
System.out.prin tln("2" );
Connection db2Conn = DriverManager.g etConnection("j dbc b2://host ip address/db name","user id","passwd") ;
System.out.prin tln("3" );
Statement st = db2Conn.createS tatement();
System.out.prin tln("4" );
String query =
"SELECT A.BJB_SCSJB_NM FROM CRYWTBT.TBSUC_J OBS A ,CRYWTBT.TBPRD_ JOBS B, CRYWTBT.TBJOB_F REQ C WHERE A.BJB_NM ='CLR606AM' AND A.BJB_NM=B.BJB_ NM AND B.BJB_NM=C.BJB_ NM";
ResultSet resultSet = st.executeQuery (query);
System.out.prin tln("Job " + "\tAverage Salary");
System.out.prin tln("-----" + "\t--------------");
while (resultSet.next ()) {
String jobType = resultSet.getSt ring(1);
System.out.prin tln(jobType );
}
resultSet.close ();
st.close();
db2Conn.close() ;
} catch (ClassNotFoundE xception cnfe) {
cnfe.printStack Trace();
} catch (SQLException sqle) {
