This example shows you how to use the String.format() method to add zero padding to a number. If you just want to print out the result you can use System.out.format(). This method is available since Java 1.5, so If you use a previous version you can use the NumberFormat class, see: How do I format […]
A batch statement can be used to execute multiple update commands as single unit in a database manipulation. This statement in the database is not executed one by one but as a single execution instead. In some cases, using a batch update can be more efficient than to execute the commands separately. In this example, […]

Since JDBC 2.0 (JDK 1.2), a scrollable ResultSet was introduced to the java.sql API family. Using this ResultSet enables us to navigate the result set in forward or backward way. To enable the scrollable ResultSet, we need to create a statement object by defining the ResultSet type (ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.TYPE_SCROLL_INSENSITIVE). If you define the ResultSet type […]
