connection with a DBMS. 7. How to Retrieve Warnings? - SQLWarning objects are a subclass of SQLException that deal with database access warnings. Warnings do not stop the execution of an application‚ as exceptions do; they simply alert the user that something did not happen as planned. A warning can be reported on a Connection object‚ a Statement object (including PreparedStatement and CallableStatement objects)‚ or a ResultSet object. Each of these classes has a getWarnings method‚ which you must

"Oak was unsuccessful so in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web." (Java‚ n.d.) Java is an object-oriented language simplified to eliminate language features that cause common programming languages. Java should not be confused with JavaScript‚ which

Many books already do a good job of that. This book assumes you are reasonably proficient in at least one object-oriented programming language‚ and you should have some experience in object-oriented design as well. You definitely shouldn’t have to rush to the nearest dictionary

Java is a language that is currently popular in industry‚ and students beginning the course are highly motivated to learn it. In 1999‚ bluej was used for the first time to teach java to introductory programming students. We had a class of about 350 students in the first year of a computing degree.
