To expertise java programming?

i want to learn java and need good programming knowledge where to start practicing .. But i knw basics of java
========================

Java has always been considered a multi-platform language - you write your code once and then you use it on almost any Operating System. Unfortunately for most Java developers, this is often taken quite literally from anyone that had no knowledge of the language, including some managers and system admins.

If you had ever seen any Java code that deals with files and directories, you already know that if the programmer is not careful, the otherwise multi-platform code will simply fail when the OS is changed. But what happens if you are careful (you use File.separator instead of hardcoded "/" .

What helped me a lot to hone my Java skills are two books that I highly recommend from O'Reilly Media, Inc. called "Head First Object Oriented Analysis and Design" and "Head First Design Patterns". Both books are using Java in there exsamples and are written in a way that isn't boring and you also memorize the learning material easily.
=====================

If you know the basic of Java that is good. If you want to learn Java, first you start from core Java, then Advanced Java. Advanced Java will cover, JSP, servlets, EJB, JMS, JNDI, JMS, Swing, etc.

In general, it is unreasonable for someone to presume that she/he learn java without studying. Some folks may require less studying than others. Nevertheless studying is usually part of the learning process. In that way, you can internalize the concepts, and learn how to take advantage of the language to not only solve the same, familiar problems, but also, to synthesize—and solve "new" problems.

hello,
One characteristic of Java is portability, which means that computer programs written in the Java language must run similarly on any hardware/operating-system platform. This is achieved by compiling the Java language code to an intermediate representation called Java bytecode, instead of directly to platform-specific machine code. Java bytecode instructions are analogous to machine code, but are intended to be interpreted by a virtual machine (VM) written specifically for the host hardware. End-users commonly use a Java Runtime Environment (JRE) installed on their own machine for standalone [URL="http://topicworld.net/forumdisplay.php/652-Java-Programming"]Java Programming[/URL] Applications, or in a Web browser for Java applets.

Standardized libraries provide a generic way to access host-specific features such as graphics, threading, and networking.

If you want to learn java from basic, you will have to start from core java and your logical power should be good. if you are good in logic then you can learn it very easily

your quote here is of immense help to me as I'm currently studying over the same programming language but in my opinion party from the theoretical base you must be ****** in crafting logic and concepts on your own .. is isn't it...

What is your programming expertise with Java? Are you good with swing, threads? How about sql?

Include more details please.

But assuming you are good with everything noted above, create a **** application using swing. Most people can't get the multi-threading right. If you ****** that, then you will be among the top *0% core java developers.

What are the approaches to learn Java programming and build up a skill in it

You can learn java,it will help you a lot.I know my sexy asian bride through java,java helps me find a good job.

A forum depends very heavily on the database structure. You want to nail that first. You don't need Java for that.

The list goes on and on.
Create a backend that will pull the data. EJB's that use plain old DAO's, Hibernate, any other ORM, or just plain JPA.
A webservice that serves it to the frontend (Possibly usng JSON for your asynchronous client).
A HTML client using React, Ember2, or Angular2.
SASS for creating CSS


This will keep you busy for a day or two :)
