Java is the most Prevalent Object-Oriented Programming language in the field of Programming. Java has a unique platform in the development field. Java has gained a considerable fan base and unprecedented popularity in the current technological world. It’s because the language deploys an easy and efficient approach to perform various programming tasks.
In the development field, there is always more to learn and apply the best ideas and concepts, if you want to become a good Java Programmer. In this post, we assembled some cardinal which will make you a good Java Programmer. We gathered some of the best Java Tips and Tricks for Java developers in this blog, which help them to become a skilful Java developer. To become a good Java Developer, one must have a strong command & understanding of Object-Oriented Programming. Without it, one can’t realise the beauty of OOPS.
7 Steps to be an Outstanding Java Developer – Java Tips and Tricks
Have Good Foundation and understanding on OOPS Language
Java offers some best features and options to the developers. People sometimes lured into learning too many things in a short span of time. As a result, they get only some bits & pieces of Knowledge on Java Programming. To be forthright, Java is one of the most accessible programming languages if you had paid attention to some basic tricks and basic knowledge of Programming. You will get frustrated if you want to learn Java in a short period
Implement what you learned
If your main motto is to pass the Java exam the next day, then go ahead and mug up all the things what you have learned and can get good passing marks in the review. If you are curious about learning Java and want to get better, then don’t try to read Java, Implementing and executing Java will gain you more knowledge, and it’s the best way to learn the Programming language.
Subscribe to Forums
In this world you are not alone who are learning Java. There are thousands of people who are working on the same technology to learn. You won’t face any challenges if you have a concept in your mind and not implementing it. The real problem comes when you start brushing your knowledge and start using it on real-time projects. Whenever you are about to begin your work on new technology, the best way is to subscribe to the relevant technology forums on the internet. Someone else in the world might help you whatever the issue you are facing, as they already overcome that issue in the past. Try to subscribe to the best technology forums on the Internet.
Don’t forget to allocate memory
This is an important and useful tip when you switch from C, C++ to Java. As Java is a dynamic programming language, the memory allocation in Java uses the “new” Keyword. This feature is not available in C, C++ language, so therefore you must take care while handling array and object declaration in Java. If you won’t use a “new” keyword, then it shows a null pointer exception in the code.
Use Strings in a correct place
In Java programming, every time a new String Object is created if the two strings are concatenated using “+” operator in a “for” loop. It increases the performance time and causes wastage of memory. Constructors should be avoided while instantiating a string. For Example:
String bad = new String (“Yet another string object”);
String good = “Yet another string object.”
Avoid Memory leaks by easy tricks
When you are writing a Java code, Memory leaks causes performance degradation of Software. Developers do not have much control over memory, as Java manages memory automatically. But still, there are some best practices which can be used to protect memory leakages.
- Always release database connections when querying is complete
- Try to use Finally block as often possible
- Release instances stored in Static Tables
Avoid creating useless objects
In Java, when you create an object, it uses a lot of memory and processor speed from the system. Without allocating memory, it’s incomplete to create an object, so to save memory it’s better not to create unwanted objects in the code.
