Techniques For All Java Programmers

Java programming language is one of the most commonly used languages when it comes to product development. When starting out, a newbie could find himself making mistakes that can easily be corrected by having the right information with him. Most mistakes in programming design are found within a code structure and syntax.

A lot of time is wasted unnecessarily in testing certain conditions. An if condition for instance should not be tested over and over again within one else block. For a newbie, he should learn on ways to utilize one if condition in order to avoid placing useless code in an else block.

You must understand that the switch statement cannot really replace an if else statement. A switch statement will run all the different cases until it has located the most relevant one. An if else statement is however easier to read. Over reliance on the switch statement could lead to poor object orientation.

Variable initialization can be done using both for the for and the do while loop. The latter however makes for better programming practice. With a do while statement, the loop will only need to be entered once regardless of the condition you want to test.

Lazy loading of complex objects is considered an efficient method when it comes to programming. However, you should set variables when they are declared together with their default values. When a variable has been assigned an initial value, the programs become worthy of forecasting in future programming instances.

Repetition is often achieved by using the same code snippet more than once. Methods can be used when coding in order to save time and also avoid this type of repetition. Break the entire code in to methods that have been well formed and you will save yourself lots of valuable time.

Any object that it not required should not be used. Unnecessary objects are considered a very expensive method of coding. They make the code heavier and in turn end up utilizing a lot of memory space. When too much memory space is used, performance is also impacted negatively.

In java, local variables may be great, but you should limit the scope of all local variables. Copy pasting old code snippets could see you insert bugs in to a program that is still under development. Reduce the scope of each local variable in order to make it more readable and less prone to errors.
