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.
The first thing to do is to learn how to use the if conditions. Do not keep on testing the same if condition within a single block. Make use of if else conditions and you are guaranteed better success.
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.
When creating any local variable, be sure to limit its scope from the moment it is created. Public variables in java are available to all. Also, ensure you do not really too much on old code. Over reliance on old code leads to copy pasting. Copy pasting in turn makes the code vulnerable to the introduction of bugs.
