Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible.
The traditional Hello world program can be written in Java as: [57] public class HelloWorldApp { public static void main ( String [] args ) { System . out . println ( "Hello World!" ); // Prints the string to the console. } } All source files must be named after the public class they contain, appending the suffix .java , for example, HelloWorldApp.java . It must first be compiled into bytecode, using a Java compiler , producing a file with the .class suffix ( HelloWorldApp.class , in this case). Only then can it be executed or launched. The Java source file may only contain one public class, but it can contain multiple classes with a non-public access modifier and any number of public inner classes . When the source file contains multiple classes, it is necessary to make one class (introduced by the class keyword) public (preceded by the public keyword) and name the source file...

Alternative PHP Cache is a free and open (PHP license) framework that caches the output of the PHP bytecode compiler in shared memory, thus reducing parsing and disk I/O overhead for later requests; and a shared memory cache for user data. For an application consisting of a large source code base such as Drupal, a 3x increase in page generation speed is possible as a result. It has been used at Facebook and has a mature codebase thanks to numerous contributors, including Facebook itself. APC was originally scheduled for inclusion into the PHP core no later than PHP 6.While multiple accelerator projects were considered desirable, the focus has since moved to Optimizer Plus, and, later, Zend Opcache that is included in the core distribution as of PHP 5.5. Since March 2013, a beta version of APCu (APC User Cache) is available, in which all opcode caching abilities have been removed to support user caches in shared memory using the familiar APC API.
