How to Use Sliders in Java Java allows you to use sliders in your programming. A slider is a component that lets a user pick a value from a set range (say, from 0 to 50) by moving a knob. A slider is a convenient way to get numeric input from the user when the input falls within a set range of values. Here a message box is displayed when the user clicks the OK button. The current setting of the slider component is retrieved and stored in an int variable named level, which is then used to create the title for the message box. #Slider #java #tutorial Java Swing | JSlider JSlider is a part of Java Swing package . JSlider is an implementation of slider. The Component allows the user to select a value by sliding the knob within the bounded value . The slider can show Major Tick marks and also the minor tick marks between two major tick marks, The knob can be positioned at only those points. Constructor of the class are : JSlider() : create a new slider with horizontal orientation and max and min value 100 and 0 respectively and the slider value is set to 50. JSlider(BoundedRangeModel b) : creates a new Slider with horizontal orientation and a specified boundary range model. JSlider(int o) : create a new slider with a specified orientation and max and min value 100 and 0 respectively and the slider value is set to 50. JSlider(int min, int max) :create a new slider with horizontal orientation and max and min value specified and the slider value is set to the average of max and min value. JSlider(int min, int max, int value) :create a new slider with horizontal orientation and max, min value and the slider Value specified . JSlider(int o, int min, int max, int value) : create a new slider with orientation and max, min value and the slider Value specified. Java JSlider The Java JSlider class is used to create the slider. By using JSlider, a user can select a value from a specific range. Java Swing Slider example In this tutorial we’ll discuss Java swing slider. In Java Swing, slider is normally constructed by a JSlider component. JSlider is a component that lets the users select a value by sliding a knob within a specified interval. For the knob, it always points to the point which matches the integer values within the interval. For JSlider, six different constructors can be used: JSlider(): creates a horizontal slider ranging from 0 to 100 with the initial value to be 50. JSlider(BoundedRangeModel brm): creates a horizontal slider using the specified BounedRangeModel. JSlider(int orientation): creates a slider using the specified orientation ranging from 0 to 100, with the initial value to be 50. JSlider(int min, int max): creates a slider using the specified min and max value, with a initial value equals to the average of the min plus the max. JSlider(int min, int max, int value): creates a horizontal slider using the specified min, max and the initial value. JSlider(int orientation, int min, int max, int value): very similar to the above one, with the orientation specified.

Java Prepared Statement extends the Statement interface, which gives you added functionality with a couple of advantages over a generic java prepared Statement object.This Java prepared statement gives you the flexibility of supplying arguments dynamically. Java Prepared Statement The Java Prepared Statement interface is a subinterface of Statement. It is used to execute parameterized query. we are pass parameter (?) for the values. Its value will be set by calling the setter methods of Java Prepared Statement. Why use Java Prepared Statement? Improves performance: The performance of the application will be faster if you use Java Prepared Statement interface because query is compiled only once. How to Use Prepared Statement in Java? A Prepared Statement in java is a pre-compiled SQL statement. It is a subinterface of Java Statement. Java Prepared Statement objects have some useful additional features than Statement objects. Instead of hard coding queries, Prepared Statement object provides a feature to execute a parameterized query.Advantages of Prepared Statement When Prepared Statement is created, the SQL query is passed as a parameter. This Prepared Statement contains a pre-compiled SQL query, so when the Prepared Statement is executed, DBMS can just run the query instead of first compiling it. We can use the same Prepared Statement and supply with different parameters at the time of execution. An important advantage of Prepared Statements is that they prevent SQL injection attacks. CODE GOES HERE---------------------------------------------------------------------------------------- private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { try { // TODO add your handling code here final String query = "Select * from employee"; final String update_query = "Update employee set edesignation = ? where eno = ?"; Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/testdb","root",""); PreparedStatement stmt = conn.prepareStatement(update_query); // stmt.setString(1, "teacher"); // stmt.setInt(2, 63); // int rows = stmt.executeUpdate(); // JOptionPane.showMessageDialog(rootPane, "rows affected : "+rows); // ResultSet rs = stmt.executeQuery(query); while(rs.next()){ String record = rs.getInt("eno")+ " "+rs.getString("ename")+" "+rs.getString("edesignation"); JOptionPane.showMessageDialog(rootPane, record); } } catch (SQLException ex) { Logger.getLogger(JdbcForm.class.getName()).log(Level.SEVERE, null, ex); } } Using Java Prepared Statement Sometimes it is more convenient to use a Prepared Statement object in Java for sending SQL statements to the database. This special type of Java statement is derived from the more general class, java Statement, that you already know.If you want to execute a Statement object many times, it usually reduces execution time to use a Java Prepared Statement object instead.The main feature of a Prepared Statement object is that, unlike a Statement object, it is given a SQL statement when it is created. The advantage to this is that in most cases, this SQL statement is sent to the DBMS right away, where it is compiled. As a result, the Prepared Statement object contains not just a SQL statement, but a SQL statement that has been precompiled. This means that when the Java Prepared Statement is executed, the DBMS can just run the Prepared Statement SQL statement without having to compile it first.Although you can use java Prepared Statement objects for SQL statements with no parameters, Java Prepared statements always treat client-supplied data as content of a parameter and never as a part of an SQL statement. See the section SQL Injection in Database PL/SQL Language Reference, part of Oracle Database documentation, for more information.A Java JDBC Prepared Statement is a special kind of Java JDBC Statement object with some useful additional features. Remember, you need a Java Statement in order to execute either a query or an update. You can use a Java JDBC Prepared Statement instead of a Statement from the features of the Prepared Statement.
