Antipatterns In Java Programs
An antipattern can be defined as a bad design in the Java language. Antipatterns will bring forth bad answers in a way that is easy for some people to understand. If you are programming with Java, it is important to understand both antipatterns and patterns. When you work with software programs, they will need to be maintained.
After you have created and released a program, you will need to make sure it is maintained. The skill of the programmer will determine if the design of the application is good or bad. Whether or not a design is good or bad is also dependent on the situation.
While using some objects may be good for certain situations, using them for other situations could be an example of bad design. Antipatterns often result from bad decisions which are made on the part of the programmer. These decisions could be made because the programmer either lacks the necessary experience, or because they have simply made a decision based on faulty information. Antipatterns are generally not discovered until an application is in the production phase. A programmer who has not worked with the software before may add an element to the product which destroys its design. If antipatterns are documented when they occur, this can allow the programmer to avoid the same mistakes on future projects.
When you are using J2EE, this is very important. The design of J2EE places an emphasis on being simple, but may programmers have made it much more complex that it is supposed to be. If you are creating a program or maintaining it, understanding antipatterns can lead you to success. When you find these patterns, you can change these patterns to get rid of the flawed designs and enhance the capability of the software. There are several parts of a software where antipatterns are very common. The first obvious area is the overall design of the software.
Many programmers will create programs with strong classes instead of interfaces. There are a number of advantages to placing an emphasis on the interface instead of the classes. You won’t have to worry about using a certain implementation, and you will also be able to easily alter the behavior during the runtime phase. The term interface can be used to denote an abstract class as well. The programs you create should never be chained into a certain code. This may not be important if you know that the behavior you are designing will never need to be altered.
Another antipattern which is commonly seen in applications is the excessive use of coupling. When you write code it is better to couple as little as possible. If you write code to perform a specific task, it should only perform the task that you need it to perform. This will keep your code crisp and clean. It will also be easy to ready and handle. Despite this, there are situations that occur when it is easy to use coupling. An example of this would be security. One method you can use to handle this is to use Aspect Oriented Programming. The AOP method will allow you to place the behavior of the aspect into the program when it is time for it to be compiled.
When programmers use too much technology, they can create antipatterns. Developers who are skilled in multiple areas will often use this technology for a large number of projects which are similar. They may do this even when it is better to use another type of technology. These individuals will consider technology that they do not know to be risky. The best way to solve this problem is to gain a large understanding of a wide variety of different programs. This can be accomplished through training. The last problem that you will run into is called input antipatterns.
This usually happens when you create Java programs that fail to handle input data correctly. For example, if you build a website that asks a user to login with a specific user name and password, it should only receive information that is correct for the user name and password. You will want to create a site which rejects characters which are not valid. If it fails to do this, a large number of problems can arise. To solve problems with input antipatterns, you will want to use what is called a monkey test.
