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 is common with any iterative loop. When initialization is to happen, the person performing the coding should not do it inside a for loop. Always aim to initialize the variables outside the loops. It makes more sense for a programmer as it makes the code more efficient.
Always assign values to a variable when you are initializing it. Even though you could be tempted to use lazy loading, assigning values when initializing the variable makes it easier to refer to later on. It also makes the variable worthy of foresting to in future scenarios.
At times a newbie will repeat himself by making use of the same code snippets over and over again. To avoid repetition, an individual can use methods instead and this is bound to save him valuable time when writing the code. Break your code down in to well formed methods and you will be able to save yourself a lot of 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.
