Eight Top Java Coding Tips For Programmers

Java is perhaps the best example of object oriented programming, leading the market for cross-platform programming languages and developing new application software. Its popularity has grown exponentially thanks to its efficient and intuitive use of programming language. As it is simple, it is ideal for newer developers, although highly-experienced developers can explore the language to extend its possibilities. Here are some tips to get the most from the language.

1. Work The Basics

Developers benefit from a wide array of options and features in Java; however, they can end up trying to learn too much too quickly as a result. The language works best if you begin by focusing on the basics, mastering them, and then moving on to more advanced features as you gain experience and knowledge.

2. Do it - Don't Just Read About It

If you want to get really good with Java, work with it - don't just read tips on how to implement it. Gain the necessary know-how and then carry out what you have picked up with real coding. This action-oriented learning approach will really embed your knowledge and accelerate it.

3. Get To Grips With Code And Algorithms

When you begin to write code, realise it first on paper - even with simple 'if/else' statements. The compiler process and algorithm looks instantly more meaningful once you have grasped the concept behind the code. Experts tend to break their Java problems into smaller parts and then create solutions that tackle each part. This will grow your confidence and experience.

4. Remember To Allocate Memory

This is especially important to remember if you are switching to Java from C++. You must use the new keyword in Java to allocate memory, as it uses dynamic language. Make sure you are careful when dealing with object declaration and array in Java. If you do not use the 'new' keyword, the code will return a null pointer exception.

5. Only Create Useful Objects

Object creation in Java uses processor speed and memory alike. Make sure you only create the objects you need to avoid wasting space and slowing down speed.

6. Choose Interface Over Abstract Class

When you learn the language, the fact that Java uses no multiple inheritance will be constantly drummed into you; however, it is also important to remember that interface is useful if you want to implement multiple inheritance without the need for the extends keyword. Interface is there to help you when things are going wrong and gives you alternative methods to work with thanks to its abstract nature.

7. Make Use Of The Standard Library

Java makes programming relatively easy thanks to its excellent set of standardised library methods. This makes it easier for you to create well-organised, efficient and flowing code.

8. Overlook Wrapper Class In Favour Of Primitive Classes

Wrapper classes are useful but can be slower than primitive classes, which only use values. Wrapper class stores data that relates to the entire class and can compare objects rather than the values stored within them.

These tips will help you to start to get the most from your Java programming journey. What other advice would you share with new coders?
