After completing this chapter, you will be able to draw strings, images, and shapes via the Graphics class in your Java programs. We discuss geometry-related classes—Polygon, Rectangle, Point, and Dimension, and the Shape interface—you will see these throughout the remaining AWT objects. You...
We explored the various ways using which we can enable assertions at the program level, package level, directory level, etc. Assert keyword and assert statements in Java and their detailed syntax with programming examples was discussed. The assert keyword and asset statements help us to use assert...

(Contrast with AWT.) synchronized A keyword in the Java programming language that, when applied to a method or code block, guarantees that at most one thread at a time executes that code. Servlets A servlet is an extension to a server that enhances the server's functionality. Servlets are ...
Continue with the installation of NetBeans IDE. To Add GlassFish Server as a Server in NetBeans IDE To run the tutorial examples in NetBeans IDE, you must add your GlassFish Server as a server in NetBeans IDE. Follow these instructions to add the GlassFish Server to NetBeans IDE. ...
So, if you’re going to be downloading and compiling the examples individually, you should first download the file darwinsys-api-1.x.jar (for the latest value of x) and include it in your CLASSPATH. Note that if you are going to build the javasrc code with Eclipse or Maven, you ...
In the absence of a JIT, the polygon drawing routines fron the AWT are relatively efficient (compared to array manipulation) and may be faster than texture mapping. Without texture mapping, walls can be drawn faster with one call to fillPolygon (rather than line by line). An exponential jump...
