The standard tools for executing java programs use a two step process. However, this isn"t the only way to run java code. class le has been type checked, and distributed code is safer. class les are simpler" for machine to execute and distributed code is faster. Minor bene t: protects your intellectual property, since there"s no need to give out the source code. To run a class, we must de ne a main method. Not all classes have a main method though. Classes can contain not just methods, but also data. Constructors can be created to ll in various datapoints for an object instantiated from a class.
