<h1>Developing Good Project</h1><strong> Author: <a href='http://www.articleseen.com/profile_Techstudent.aspx'>Techstudent</a></strong><br /><p>Read this article if you have at least some experience as a Java programmer and knowledge of OOPs concepts. Try to follow these basic details while developing the project so that you can achieve good level of maintainability. (1) Hide Implementation details As Java is an object oriented programming language, it provides encapsulation. Always hide the implementation details by utilizing the encapsulation. Encapsulation hides the internal state of the object and performs all the interactions through methods. So, the internal implementation details will be safe from outside hackers. (2) Don’t do much subclassing It is always better not to subclass more than two to three levels deep. Only create a subclass if it is strongly necessary for adding important specific functionality in a separate class. (3) Use local variables when possible rather than instance variables When applicable, it is always better to make use of variables that have small scope like local variables declared in blocks, methods or loops. (4) Initialize local variables Local variables have to be assigned a value before they are used because local variables are not initialized automatically like the instance or static variables. (5) Utilize Overloading If two or more methods are doing the same job but have to handle different method arguments, assign the same name to all those methods but with unique method arguments. (6) Don’t use too much arguments in a method If the method is taking too much arguments then think of creating its own class with all that stuff. (7) Utilize Interfaces If you want to protect your code by showing only the definition to outside world and hiding the implementation details, make use of interfaces (8) Only create an object when it is really necessary Avoid creating objects thinking that they may come to use later in the code as this may lead to lag in the performance and unnecessary confusions. (9) Manage objects Always watch the objects you have created. If they are no longer useful, set them to null for better memory management and avoid confusion. (10) Don’t nest if or if else blocks heavily Always better to design and follow simple logics rather than using deeply nested blocks. Consider writing separate methods for inserting those logics. (11) Use meaningful names Always use meaningful names for variables, methods, classes, interfaces and Exceptions. (12) Declare a method as static only if necessary Using non-static methods is always better than using static methods as the non-static methods contain the knowledge of the current object. But if you want to know some things which are not object specific, then make use of static methods.
