So the question arises, how to start learning Java?

Great demand in the industry: Billions of devices run on Java and being in great demand offers highly paid jobs.

Needs no pre-processor don't need to include any header files to create Java applications.

Thus, you can leverage and benefit from the OOP features.

Object Oriented: Java is a class-based, object-oriented programming language.

Java also doesn't support explicit pointers leading to more security. Java is also secure since these programs run inside a virtual machine which is known as a sandbox.

Robust: Java provides robust tools such as better inbuilt exception and error handling, helping build reliable and error-free programs.

Java can define multiple threads and thus execute multiple tasks at the same time.

Multithreaded language: Threads are lightweight sub-processes.

Platform-independent: Java supports WORA and provides cross-platform benefits, so code written in Java can run on any Java-supported platform.

Easy to learn: Java syntax is clear and concise, thus easy to learn.

Java, other than being reliable and secure, it is :

Installation and set-up procedures for Java.

In this Java tutorial you should learn about : What will you Learn in This Java Tutorial?

JAR files are used to package multiple Java files together into a single file, analogous to zip files. JAR Files JAR stands for Java Archive.EJB(Enterprise Java Bean) a Java tool, helps in building these programs. For execution, servlets process these requests and produce a response, to be sent back to the webserver.Īs discussed earlier, these are distributed applications, a little complex in nature. Servlets basically handle the requests sent to web servers by clients. Java Servlets run on web servers or application servers and are used to generate web applications. Java applets are small Java programs that can be executed on a client computer with a web browser after being downloaded from a website. These are freestanding programs that function on their own and do not require any services of OS to run.Įxample - Media Player,Text Editors,Antivirus etc

Standalone Programs also called desktop applications, are the software that require to be installed on each system before being run. Mainly you can create the following programs using Java. For application servers, we have JBoss, WebSphere, WebLogic, etc. As for web servers Apache Tomcat, Rimfaxe Web Server(RWS), Project Jigsaw etc are all based on top of Java. Java ecosystem provides a huge number of web servers and application servers. As per Oracle, 97% of the total enterprise applications are built on Java. Java is the most preferred language in this domain.

JSP(Java Servlet Programs) Struts, Spring, Hibernate, JSF are some of the technologies for creating web applications in Java.Įnterprise Applications Applications are created to satisfy the needs of an entire organization than an individual. Web Applications: Several Tech Giants like Amazon have their web applications built on Java. Tools like JavaFX, Java Foundation classes help in the creation of desktop applications. Netflix, Uber, etc are also Java-based.ĭesktop Applications: Several desktop tools, Acrobat Reader for example are developed using Java.

Android application development is based on top of Java.

Mobile Applications: Java provides a cross-platform framework called J2ME to develop mobile applications. The learning curve for Java is low, leading to better developer access. When compared to other programming languages, Java is faster than Python due to its support for concurrency and multithreading features, code written in Java is more maintainable than of C++. In Java, programs are compiled into byte code and the byte code is executed by the JVM making the byte code platform-independent. WORA, basically means, Java code compiled on one system can run on all other Java-supported systems without the need for any recompilation. Java applications are run by a run time engine called JVM, Java Virtual Machine, they are also called WORA, which stands for Write Once Read Anywhere. It was developed by James Gosling at Sun Microsystems in 1995.

In a pure OOP language, we should access everything by message passing through objects but in Java we have static variables and methods that can be accessed directly without the objects.

It provides support for primitive data types like int, char, etc which are non-object,.

However, it is not considered pure object-oriented, because: Java is a high level, general-purpose, objected-oriented programming language.
