How do I become a good Java programmer?

Java is a very successful and popular programming language. It is very reilable and is widely used in our day to day lives, prominently seen in web or mobile applications. There is much demand for Java these days and the Java programmers are being recruited largely in the Information Technology sector.
For being a good Java programmer you must focus on certain things mentioned here:

  • Get your basics clear –
    Find a good source of knowledge be it a tutor or online videos or study material and strengthen your basics. Understanding basics is a must for further constructing your programming skills. Rather than mugging up something that you don’t get, seek help and get the logic behind it. Take your time, don’t have the target of getting everything at once, take it slowly at the starting and then gradually you’ll pick up speed. You should learn:

    1. Java 8
    2. Spring Framework (Spring Boot)
    3. Unit Testing
    4. APIs and Libraries
    5. JVM’s Internals
    6. Design Patterns
    7. DevOps Tools
    8. Kotlin
    9. Microservices
    10. Learn Your IDE Better
  • Read documentation and open source frameworks source code –
    Keep yourself updated about the latest Java technologies by joining some good forum and subscribing to newsletters. Never stop reading. Keep reading about it from somewhere or the other and try and spread your knowledge to others. It’ll also help to maintain your interest in the field. Build a habit to read lots of documentation. May it be specifications, JSR, API documents, tutorials etc. Reading documents helps you creating that essential foundation based on which you program in best of the way.
  • Practice Coding
    Implement what you are learning. Practice programming online or offline, that’ll boost your confidence. Be regular, make targets and try and complete them withing time. Depth of knowledge comes only when you practically perform what you’ve understood. Join Java Programming Practice and Contest, like: codechef, spoj, and projecteuler.
  • Group discussions and read books –
    Make a group, have discussions. Join hubs on internet. Group discussions help you to get different views regarding the topic. You can get the pros and cons of things and you can also solve your doubts over discussions. Also, read standard books and notes.
  • Subscribe to forums –
    When you start working on a new technology the best and first thing to do is to subscribe to technology forums. Whatever the issue you are facing, someone else might have already faced it earlier and you might find the solution. Follow good blogs and also help others by sharing your opinions on it. Join Java programming social plateforms, like: StackOverflow, dreamincode forum, java-forums, and coderanch forum etc.
  • Undertake projects –
    A good way to improve your coding skills and become a good programmer is working as a freelancer. It means that you find projects online, work from home and get paid online, too.
  • Dedicate yourself –
    The last and the most important step that’ll you need the most is dedication. You’ll only be a good java programmer if you truly dedicate yourself towards it. Don’t have a casual approach but concentrate and hold your focus on it. Follow Java tutorials by GeeksforGeeks.
