Java programming tutorial Java technology has changed our life as most of the devices we use today uses it, thats why to learn Java programming is a good thing.

Here is a quick Java tutorial, its an object-oriented computer programming language like C if youre familiar with it or any other object-oriented programming language, then it will be easier for you to learn it.

A Java program consists of classes that contain methods; you cant write a method outside of a class.

Consider the following program: class ProgrammingLanguage attributes String languagename; String languagetype; constructor ProgrammingLanguage ( String n, String t ) languagename n; languagetype t; main method public static void main ( String args ) creating objects of class ProgrammingLanguage C new ProgrammingLanguage ( C, Procedural ); ProgrammingLanguage Cpp new ProgrammingLanguage ( C, Object oriented ); calling method C.

The class has two attributes language name and type; we can create instances of the class using new keyword.

The constructor method (has the same name as that of the class) is invoked when an object of the class is created; we use it to name the programming language and its type.

Main method is a must and acts as a starting point of a program, the display method is used to print information about the class object.

A class name begins with a capital letter, and if there are more words in the class name, then their first letters are also capital.

For example, MyJavaClass is a class name, and for methods (functions in CC), the first letter is small and in other words, the first letter is capital, for example, myJava is method name.

These are only conventions but are useful in distinguishing classes from methods.

Java has a very rich API to build desktop and web applications.
