In JavaFx, a Scene represents the visual content of a stage. The Scene in JavaFx is represented by the Scene class from the ‘javafx.scene’ package. JavaFx stage shows the scene in it & only one scene can be present in a stage. If scene goes to a different stage, JavaFx first detach it from the current scene.
Java Swing provides Icon interface and any class which implements it is an icon & this way we can create custom icon. The Icon interface will ask you to implement three methods to decide the size of the icon and to perform icon drawing. In this example, we will create rectangle icon and use it with the JLabel component.
Let us say in a SQL Script, in Stored Procedure, or in a function, we want to process the data record-by-record. In this case, we can go for a SQL Cursor. Note, using Cursor is not advisable as it eats up memory, network bandwidth and performs lock while processing the records. So, before writing a cursor think twice and use it when no other options are available. With this overhead, we will get full control over the record processing. In this example, we will create a SQL cursor to fetch record from the Jobs table of the pubs database and list the records. In real world, after reading the record, there will be business logic that performs various other actions based on the fetched data.
In this Java IO Tutorial, we will deserialize object written in a file. Here we will use ObjectInputStream and readObject.
In this JavaIO Tutorial, we will serialize collection of Line class instances using ObjectOutputStream and its writeObject method.
