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.
We can create see-through JavaFx Stages using the Opacity property. This property accepts a double value which ranges from 0 to 1. The value can be changed or fetched using the function getOpacity and setOpacity methods.
Lambda expressions are new feature of Java 8. With Lambda Expression function call sequence becomes more easier compared with earlier releases of Java. In this example, we will learn about Lambda expression and use it for Functional Interface. When an interface contains only one abstract method, we call it as functional interface
In some case, we may need to pause the execution for certain period say for example 5 seconds. And in some situation, we may need to pause the execution till some time of the day elapses. In this example, we will see how to introduce execution delay in SQL Server T-SQL Script using the WaitFor clause.
