longer-lived objects still accumulate in the old object memory area. Occasionally, based on low-memory conditions or programmatic requests, an old object garbage collection must be performed. The Java HotSpot VM by default uses a standard mark-compact collection algorithm, which traverses the entire...

If the program sets the L&F before a look and feel is needed, the UI manager tries to create an instance of the specified look-and-feel class. If successful, all components use that L&F. If the program hasn't successfully specified a L&F, then the UI manager uses the L&F specified by...
Just like the PATH your system uses for finding programs, the CLASSPATH is used by the Java runtime to find classes. Even when you type something as simple as java HelloWorld, the Java interpreter looks in each of the places named in your CLASSPATH until it finds a match. Let’s work...
