Check if record exist in database?

I'm connecting to mysql server using Java.

In VB, I once used a condition

if (rs.BOF=true and rs.EOF=true) then
// display error message that the recordset stated by the SQL String
doesn't exist

How do I check if the resultset exist in Java?

public void executeQuery(String query) {
if (connection == null || statement == null) {
System.err.println("Message Error!!");
return;
}

The resultset will always exist. If you are asking how to check if it
contains any records, you just try to read the first record. If it isn't
there, then the resultset is empty.
