In Java, how do I set a return type if an exception occurs?
- by beagleguy
hey all, I'm new to Java and was wondering if I define a method to return a database object
like
import java.sql.*;
public class DbConn {
public Connection getConn() {
Connection conn;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
if(System.getenv("MY_ENVIRONMENT") == "development") {
String hostname = "localhost";
String username = "root";
String password = "root";
}
conn = DriverManager.getConnection("jdbc:mysql:///mydb", username, password);
return conn;
} catch(Exception e) {
throw new Exception(e.getMessage());
}
}
}
if the connection fails when I try to create it what should I return? eclipse is telling me I have to return a Connection object but if it fails I'm not sure what to do.
thanks!
