Programming Fundamentals/Introduction Examples Java

Overview Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers “write once, run anywhere” (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java was originally developed by James Gosling at Sun Microsystems and released in 1995.Wikipedia: Java (programming language) Java is one of the most popular current programming languagesTIOBE: Index and is often used in computer science courses. Example Hello World // This program displays "Hello world!" // // References: // https://introcs.cs.princeton.edu/java/11hello/HelloWorld.java.html class Main { public static void main(String[] args) { System.out.println("Hello world!"); } } Output Hello world! Discussion Each code element represents:Programming Fundamentals/Hello World // begins a comment class Main begins the Hello World program { begins a block of code public static void main(String[] args) begins the main function System.out.println() calls the standard output print line function "Hello world!" is the literal string to be displayed ; ends each line of Java code } ends a block of code Java IDEs There are many free cloud-based and local IDEs available to begin coding in Java.
