Refactoring is largely composing methods to package code properly. Long methods can be troublesome because they contain lots of information that gets buried by the complex logic that is contained.
Refactoring should be done all of the time, in little bursts, rather than timed in specific intervals, like every two weeks. There is a rule of three to go by when refactoring: You create the initial action, you duplicate the action, you refactor the third time. The most common time to refactor when you want to add a new feature to some software. This will also help you understand the code you need to modify.
Refactoring can also fix misdeeds. Sometimes a design is not created in the most efficient way to add enhancements. Refactoring is a quick and smooth process that can make adding the feature go much more quickly and smoothly. Programs have two kinds of value: what they are doing for you now and what they can do for you in the future.
Refactoring can also help fix bugs. In fixing bug,s much of the use of refactoring comes from understanding the code. This active process of working with the code helps in finding the bug.
Some attributes of difficult programs are programs that are hard to read. If a program is hard to read, it will be difficult to modify the code. Programs that have duplicated logic are difficult to modify and programs with complex conditional logic are hard to modify. XML training will give you some useful refactoring skills to use and practice with.
Refactoring is taking an existing program and adding to its value. Not by changing its behavior but by giving it more of these qualities that enable us to continue developing and organizing data efficiently.
