As a functional programming language, Java is used widely for developing a variety of modern applications in different environments. Like other programming languages, Java has its own syntax rules and structure. But Java, unlike other programming languages, does not run directly on the computer’s processor. After being compiled to bytecode, the Java programs can run on any Java Virtual machine (JVM).
The feature enables developers to run the same code on multiple platforms without recompilation. However, Java is considered to be slower than other programming languages due to the feature. The introduction of just-in-time compilation has drastically optimized the performance of newer versions of Java. That is why; it is important for programmers to understand some common Java myths.
Java Performance Misconceptions Each Developer Must Overcome
No Need to Switch to Latest Version of Java
Like other programming languages, Java is also being updated regularly with new language features. The features and enhancements also make Java perform in a better and faster way. But many developers still feel that newer versions do not affect the programming language’s performance.
No Need to Focus on Performance of Operations
The expensive operations often affect an operation’s speed. But many developers ignore the significance of breaking down more expensive operations into cheaper ones. Along with improving Java’s performance, the conversion of expensive operations will further help organizations in managing bottlenecks like hardware.
64-bit Code Makes Java Slower
While using 64-bit code, programmers use pointers that are almost twice as large as the pointer required by 32-bit code. As the lager pointers require additional memory, many programmers feel the code will become slower. But Java programmers have option to use additional registers provided by 64-bit code to reduce the load on processor. The intensity of registers further makes Java code work faster.
Avoid Multithreading
Many programmers find multithreading complex and time-consuming. So while writing Java code they try to avoid multithreading. Multithreading will become a mess if the programmer try to combine a bunch of code and a bunch of threads. The programmer can simplify multithreading by using only require threads and controlling the way threads interact with each other. At the same time, the entire team must follow the same patterns and rules to make multithreading simple.
Add the Final Keyword to Run Code Faster
Many Java programmers include the “final” keyword to make their code run faster. They believe that the keyword will keep the JVM inline. So it will be easier for them to compile and run the same code across multiple platforms. But the final keyword, in real-time, does not impact the way JVM functions. That is why; no developer can run his code faster simply by using the final keyword.
Object Pooling Makes the Code Faster
It is a common practice among Java programmers to reuse the same objects by pulling them on and off free lists. Along with avoiding new objects, the option also help them in effectuating garbage collection. The garbage collector does not pick the existing objects during code execution. So the object pooling enhances the performance of Java code. However, the programmers must synchronize the free list each time multiple threads go off the pool. If the free list is not properly synchronized, it will generate scaling bugs. So the programmers must check and synchronize the free list regularly to make the code run faster.
Along with understanding these common Java performance myths, programmers also need to understand the features of the most recent version of the programming languages. For instance, Oracle released Java SE 8 with several new language features. The features and enhancements further make Java one of the high-performing programming languages in the market, while making these myths and misconceptions out of date.
