#Learn java in one day and learn it well code#

Since object creation is incomplete without allocating memory to it, it is better to keep the object requirements under check and not create unwanted objects in the code. When you create an object in Java, you use up memory and processor speed from the system. Note the difference in array declaration in Java and C or C++. Not using the ‘new’ keyword will show a null pointer exception in the code. C, C++ does not explicitly have this feature, therefore you must take care while handling array and object declaration in Java. The memory allocation in Java using the ‘new’ keyword is a necessity as Java is a dynamic programming language. This tip is particularly useful for those who switch from C, C++ to Java. When you start getting the solutions right, you will get the confidence to work more. Even for experts, the best way to solve a complex problem or to formulate an algorithm to solve a Java program is to break the problem into sub-parts and then try to devise a solution for each sub part. The algorithm and the whole compiler process will look so meaningful once you understand the idea behind the code.

Understand your code and algorithmĮven if you are writing a simple code having a ‘if else’ statement, as a beginner, start by realizing the code on a piece of paper. You can never learn Java if you are not willing to get your hands dirty. Gain knowledge and then execute what you have learnt, in the form of code. However if you are really serious about learning Java and getting better at it, the best way to do it is not by reading, but by implementing. Well, if your sole purpose of learning Java is to clear the exam you have the next day, go ahead and mug up all the things that you can and you might just get the passing marks. Trust me when I say this, Java is one programming language which is easy if you have paid attention to the simple basics, however it can be frustrating if you get greedy and try to take the shorter route forward. As a result of this, they get ‘bits and pieces’ knowledge of a few options that Java offers, but their basics hang on a loose thread. Get the basics rightĪs Java offers so many features and options to the developers, people are sometimes lured into learning too many things in too little time. Being a good Java developer is always within touching distance of any computer programming enthusiast, however it is standing amongst the very bests that matters.īelow are some tips that might help you grow as a Java developer and gain more knowledge about the language. Its simplicity can sometimes be a distraction and the highly experienced Java developers have always aimed a notch higher and have tried to explore the different possibilities that the language offers. The reason Java has gained such a large fan base and unprecedented popularity is because the language deploys a very easy and efficient approach to perform various programming tasks and aid the developers. Developed by Sun Microsystems, Java leads the way in terms of cross platform programming language and developing application software.
