Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    Class.forName("com.mysql.jdbc.Driver");
    Connection connection = DriverManager.getConnection("jdbc:mysql://localhost/testdb", "root", "");

    // Move to the second row
    resultSet.absolute(2);//from w  ww .  ja v a2  s.c  o m

    // Move 2 records forward from the current position (fourth row)
    resultSet.relative(2);
