AWT uses a set of peer interfaces. The peer interface makes it possible for a pure Java-language graphic component to use a corresponding real component—the peer object—in the native environment. With AWT, you don’t generally deal directly with peer interfaces or the objects behind them; ...
This Swing Java Tutorial describes developing graphical user interfaces (GUIs) for applications and applets using Swing components
This class provides a lightweight wrapper fororacle.sql.DATE, the Java representation of the DATE database type. This wrapper allows an instance of theoracle.sql.DATEto be used as an immutable domain object. The intent of many of the methods in this class is to wrap the corresponding method...

of working with raw SQL tables and queries. It also allows observing changes to the database data (including collections and join queries), exposing such changes via LiveData objects. In addition, it explicitly defines thread constraints that address common issues such as accessing storage on the ...
Unable to instantiate Java object of class <insert_1>. Severity 20 : Error Explanation An instance of the Java class could not be instantiated. Response This is an internal error, possibly due to a faulty installation. Check messages in the system log for related errors and retry the operatio...
Just cloning this repo and building the project, we get this error: java.lang.NoClassDefFoundError: Could not initialize class components.Stark
Within a component, a Java class is declared as public, because a number of other classes from different packages need to access it. In Java, there is no way of denying the use of this class to a user from outside and, simultaneously, allowing unrestricted use inside. This can be solved...
Another problem you encounter is that lombok does not use AspectJ, instead it seems to be a compiler plugin of some sort that hooks into IDEs (some might require plugins) and maven/gradle compilations. Though it also provides a java agent that might work with invesdwin-instrument. Full examp...
In this chapter and those that follow, we will take a look how to design applications out of components. Specifically, we will look at: The architecture of distributed applications, including Windows DNA What makes up a Web application What are components A quick introduction to ActiveX and...
