Problem
Learning JAVA
Solution
public class HelloWorldConsole { public static void main(String args[]) { System.out.println("Hello, World!!!"); } } // classic hello word in JAVA
Detailed explanation
- JAVA is case sensitive
- Not to be confused with JavaScript.
Java is a programming language originally developed by James Gosling at Sun Microsystems 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 ofcomputer architecture.
Principles
There were five primary goals in the creation of the Java language:
- It should be "simple, object oriented, and familiar".
- It should be "robust and secure".
- It should be "architecture neutral and portable".
- It should execute with "high performance".
- It should be "interpreted, threaded, and dynamic".
