Software programs are preferred only when the output it produces is worth enough. Programming tools not only help to develop the program and applications, it also helps to maintain the code and debug in case of any critical issues. Best programming facility benefits users and will prompt the user to opt for that particular programming tool. Most of the code base that you write should be immutable. Immutability will facilitate hackers to hack the code base and extract the most crucial information of an organization.
Few best practices specified by the programmers have been summarized in this article to help you excel in programming:
Minimization of Mutability – Software Programs
Always write your code in such a way that it is immutable and cannot be modified once it is written. All the state information will be provided at the time of creation of objects for a class and it is fixed for its lifetime. Certain classes of Java Libraries, String Wrappers, and Big Integers are immutable and can be used anywhere in the code base by using just their references.
Immutable codes are always thread safe and hence only one modification can be made simultaneously which in turn will reduce the redundancy data and thereby improves the speed and performance of systems. The only disadvantage of these immutable codes are that they are very expensive when included into the programming language.
The following are some of the tips you can get benefitted with for obtaining an immutable code by using the software programs are as follows:
Always make the class that has to be immutable to be Public Static Final class. Since the class has been declared Final, it will not allow the users to make any changes to the methods or variables defined in the class. Also make sure that these classes are not extended when it is declared as Final.
Avoid creating setter methods in these classes. These methods (setters) are also called as mutators which will allow the users with more flexibility in making changes to the code base and hack the entire system.
It is advisable to provide appropriate access controls to any mutable components to ensure safety of the systems.
Researchers always suggest the programmers to make all the constructors to be private except for the few constructors that need to be used in other classes.
Ensure that the fields are made Final and methods are made Private to make a class more immutable.
