Java Based Optimization
Okay, so app developers and language programmers, you guys always want to fully optimize the performance of your program. Which is a good thing, but numerous developers also believe that optimizing a programing language or an application isn’t an easy task?
Well, which is by the way true because to fully optimize the program a high caliber of technical skills and knowledge required. And, most of the optimizations are based on the Java strings, so Java knowledge is the must. But, guys, it doesn’t mean that with the little basic knowledge and few simple tricks, you can’t optimize the program.
We have churned out few very basic and easy program optimization tricks for you all. Well, let’s first study few general optimizing techniques, and later we can focus on Java-based tips.
#1. Understand The Necessity Of Optimization
Yes, the first tip would be to determine whether your program required optimization in the codes or not. Because disturbing already well-structured code is both wastes of time and energy. And, moreover, it will make the code more hard to read and understand.
So, how to determine the need and extent of optimization?
This is a very simple, first make sure how fast you want the code to respond. That can be done by specifying a maximum response time for all API calls or a number of records you want to transfer in the time frame. So, according to this only optimize the part which actually requires optimization.
#2. Use Profiler
So, once you know the part which you want to optimize, then you have two options in front of you. Either rectify the code which looks clumsy or can simply use the schedule profiler to better make sure the performance. Well, yes, using profiler is the best option in every case.
#3. Run Test Suit
This a general tip, but it can be turn out very helpful. You should run test suit after and before the change. This will determine the extent of change in function and performance takes place because of your change.
#4. Tackle Big Issues First
Well, once your profiler is ready, you have the list of all the issue that required your attention. So, here you might be tempted to solve the easy problems first, but it is advised to tackle the major issue first. Because they required your more attention and focus.
#5. Use StringBuilder
There are plenty of options available to concentrate string in the Java, such as old trusted StringBuffer or new StringBuilder. In every situation, a different tool is required to concentrate strings, but most of the time StringBuilder can be your trusted go-to option.
#6. Use Primitive
So, for better performance and result use primitive types of applications instead of their wrapper classes. It is better to use an int instead of an Integer, or a double instead of a Double. That allows your JVM to store the value in the stack instead of the heap to reduce memory consumption and overall handle it more efficiently.
So, fellas, these are just a few highly simple optimization tricks as we have numerous other tips stored up for you also. That’s why stay tuned for more optimization tips.
