5-Steps that Java Learning Centres Teach You

Posted by GuduruKarthik on November 3rd, 2014

We all use Java in our daily lives, without even realizing it. Like playing online games, using online word counting tool, chatting with our friends, viewing 3D images etc. Sometimes we are asked to install java in order to open certain websites. If such is the power and usage of Java in the field of internet, imagine its role in all other fields. With Java being used everywhere there is huge demand for java programmers. In order to make the demand and supply curves meet Java learning centers are set up in various parts of the country.

Java is a high-level language which runs over 50 million computers and on billions of devices in the entire world. Around 9 million developers have created useful applications using Java in all major industries. Its main USP remains to be the ‘Write Once, Run Anywhere’ feature - which means it can be run on any device.

But before you start coding in Java, there are certain steps to be followed:

 1. Knowing the Basics

Whichever new course we are learning, the first thing we need to do when we are starting from scratch is to get acquainted with the basics. A great introduction can be provided by an online guide, textbook or a trained professional in Java learning center. They explain what Java is, how does it help us, how to use it and shows how it works. They introduce the technical jargon, necessary tools and concepts required to begin learning Java

2. Learning through Practicing

It is important to practice what you’ve learned. It can be a simple program to display the number or text entered. But make sure to use the predefined functions learnt in step 1. You can learn much by developing a very simple program rather than simply seeing a complicated program created by someone else. And next time when you see the code in the study materials, you can relate to it and understand its function from the code without the need of the gist given. It will familiarize you with naming conventions, syntax, indentation rules etc. And the best way to improve yourself is to do it, test it and redo it, this time correctly. And after you reach this stage, you can challenge your skills with tougher tasks.

 3. Draft algorithms before coding

Before creating a code, analyze its purpose. Then, create a step by step approach by using the Java’s flow of control and branching mechanisms. The algorithm shows how to solve a problem or function as per the requirement and how it gives the exact output. Algorithms helps to get a proper insight into the purpose of the code even before you start coding, you can get a hint of the situations where problems might occur and this helps you plan your solution to deal such problems. Write the code and run it. If the output is as expected then congratulations, if not go back to the algorithm and compare it with your code. Make the necessary changes.

4. Coding on a paper

It is another useful technique for beginners in programming. While programming on computer means mental analyzations and calculations, on paper it means detailed understanding which is ‘thinking like a compiler’. Analyzing a hand written code, allows you to save the changes made after every review, showing your improvement and thought process. This practice may give you hard time initially, but as time advances you will know its use. This technique is often used in Java Learning centers set up to train freshers.

5. Read, read and read

Java is an ocean and to delve deep into you need to be updated. So follow all the sources available online, read textbooks, know the latest developments.  There are many online forums which act like online Java learning centers, where programmers share their ideas, problems, learning techniques and many more.

Learning Java puts a very powerful and useful tool at your fingertips. Java is the top most sought after language, and the big market is waiting for you.
