Classpath is a parameterâset either on the command-line, or through an environment variable âthat tells the Java Virtual Machine or the Java compiler where to look for user-defined classes and packages.imilar to the classic dynamic loading behavior, when executing Java programs, the Java Virtual Machine finds and loads classes lazily (it loads the bytecode of a class only when the class is first used).
The default class path is the current directory. Setting the CLASSPATH variable or using the-classpath command-line option overrides that default, so if you want to include the current directory in the search path, you must include  . in the new settings.he runtime tool java has a-cp option, as well. This option is an abbreviation for-classpath. For very special cases, both java and javac have options that let you change the path they use to find their own class libraries.
