Pack200

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Pack200 is Sun's compression utility included in Java 1.5.0. It was designed for compressing JAR archives. Using Pack200 compression can reduce the size of a JAR by about 60%. Java is a programming language originally developed by James Gosling at Sun Microsystems (which is now a subsidiary of Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. Java is general-purpose, concurrent, class-based, and object-oriented, and is specifically designed to have as few implementation dependencies as possible.
