Reading a file from filesystem and printing it’s content in console.Taking input from console and printing it.Later you can include more APIs and more such programs as much as you can. Your goal is to familiarize yourself with these APIs, so always look for a solution within these APIs only.Īgain I am suggesting a few basic programs you can work on to start with. Please note that you should always try to find an existing API for doing a particular task, and you should not be creating your logic here. Just start exploring various classes and interfaces involved in these APIs and start creating programs for them. Here, I suggest you work hard on learning Java APIs inside java collections and java IO. When you are done with making most of the basic programs, and most importantly, you are comfortable creating such basic programs, jump to the next step. Learn Java APIs and Write Few Complex Programs The list can be long, and I suggest you add more items to it and create programs for them.Īnd remember, Google is your friend :-) 3. The above programs give you a start and make you understand what I meant by basic programs. printing output in array format in console. Create some programs involving array e.g.Create two classes (super class/sub class) and practice method overloading and overriding concepts.Build a calculator program able to add/substract/multiply and divide the numbers.Swapping between two numbers using any technique you know.
Here you will have to start writing some fundamental java programs e.g., hello world, simple addition and subtraction etc. Once you are confident that you are familiar with the essential keywords and concepts and can relate them somehow, you are welcome to the second step. Just like other popular programming languages, Java is also an object-oriented programming language.
Notes will help you to measure your java learning curve.Ĭarefully learn object-oriented programming concepts. Don’t worry about you are wrong or right connect them, and better make notes. If you can still not connect the pieces of information spread in multiple places, keep repeating this step until you start relating the core concepts. This time, things will start making more sense to you, and you will be able to connect between various concepts by yourself. When you are done with a few links as the two above, re-read them again the second time. You can do a quick google search and find out many similar links. Please keep in mind that the above two links are not the only links for basic knowledge. What I expect from you is just to read all the text available in the below links, even if it just doesn’t make sense to you in the first attempt. Initially, I do not expect you to become the master of all basic java concepts like keywords, core concepts or basic coding techniques.
If you don’t know the basics, you will never know what to do next or what you are doing wrong. This is the first step for a self-evident reason. Make sure you have prepared your Java development environment, i.e., You have installed JDK/JRE and an IDE like Eclipse. Even better, suggest to others what you think is better to learn Java fast or quickly. If you do not like my suggested way to learn Java, ignore this post and continue with what suits you best. I am writing this post dedicated to all my young fellows ( or I should say beginners) who want to attain a certain level of proficiency in Java technology and where they would like to take my advice. Every month, I am asked the same question by many blog visitors ( primarily beginners) about learning Java.
