Important Pointers For Java Programmers To Follow
When it comes to programming, there are concepts that the seasoned experts may consider obvious but which a newbie may not be familiar with. In Java programming, each person is bound to make mistake or two when starting out. The mistakes will usually be found in the code structure and syntax and can be avoided with the right tips.
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.
Learn of different ways to use the switch statement and the if else statement. These two statements are used in very different scenarios. A switch statement can for instance be effective in returning a result by selecting the most relevant. The if else statement will however make it easier to read and understand the entire code.
When initializing a variable within any iterative loop, avoid using the for loop. Instead make use of the do while loop. This loop can be entered once irrespective of condition being tested by the programmer. Initializing variables outside the loops is a very good programming idea.
Lazy loading is a programming idea practiced by any newbie. Rather than use lazy loading of complex objects, you can set the default value to all variables when they are initialized. Values can be set when the variables are being declared.
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.
Lazy initialization can also be used in place of making unnecessary objects. Making of unnecessary objects is considered an expensive process in that leads to utilization of lots of memory. This could also impact on the performance of a program.
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.
