Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by 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 it has fewer low-level facilities than either of them.Oracle Corporation is the current owner of the official implementation of the Java SE platform, following their acquisition of Sun Microsystems on January 27, 2010.The Oracle implementation is packaged into two different distributions:Java Runtime Environment (JRE) which contains the parts of the Java SE platform required to run Java programs and is intended for end users.Java Development Kit (JDK) which is intended for software developers and includes development tools such as the Java compiler, Javadoc, Jar, and a debugger.Garbage Collector :Java uses an automatic garbage collector to manage memory in the object lifecycle. The programmer determines when objects are created, and the Java runtime is responsible for recovering the memory once objects are no longer in use. Once no references to an object remain, the unreachable memory becomes eligible to be freed automatically by the garbage collector.The traditional “Hello, world!” program can be written in Java as:HelloWorldApplication.javapublic class HelloWorldApplication {    public static void main(String[] args) {        System.out.println('Hello World!'); // Prints Hello World! to the console.    }} - Study24x7
