Programming can be very exciting for a person who has already learned all the ropes. It can however be frustrating if a programmer keeps on encountering the same set of mistakes every time he is coding. Mistakes are very common in Java programming, but with the right tips, the programmer is able to make better use of his time by avoiding obvious mistakes.
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.
Switch statements, though effective, cannot be used as a replacement for an if else statement. Poor object orientation is often the end result of over relying on switch statements. Use if else statements for better coding results. The results are not the only benefit provided as the statements also make it possible to read the code with ease.
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.
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 achieve by using the same code snippets over and over again within the same code that is being developed. Avoid repetition, by using methods. Take time to form methods and they will take care of the repetition problem. The methods will then be used all over your code.
When coding, avoid creating unnecessary objects. The reason you need to avoid this is so as to ensure that you do not end up using too much memory. When too much memory is used, the program becomes very slow. This will in turn have a negative effect on your performance.
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.
