Are you a QA offshore specialist or a development manager involved in an Enterprise IT organization? You may be aware of the debate whether the uses of Java is the best programming language for your backend development.
If you are part of a start-up company, the situation could be different. Some of your firm’s app developers could be opting for Ruby on Rails or Scala, while others are championing Java QA automation or seeking Java QA consultation for their existing tasks.
Why Java is best for backend development
#1 Highly scalable
Java is known for its scalability. In the case of Java EE, when you have conducted the right planning and selected the appropriate application server, the Java EE can work in transparently clustering the instances. Also, it enables several instances when undertaking requests.
In Java, separation issues require improved scaling. If processing or Input-Output (IO) soars, you can handily make use of available resources and do load redistribution. Concern separation enables transparency to the app.
Java parts are readily available. This allows for easy scaling of huge web apps. With a flexible language, you need to have less invasive coding to enhance scalability.
#2 Cross-platform Java employment
Java's main benefit is its ‘Write Once, Run Everywhere (WORE)’ feature. This feature is also known as portability. As a developer, you can work on a compiled Java program on available platforms that contain a JVM. This involves all existing platforms such as Windows, Mac OS, and Linux. Initially, you can write your Java program using .java file. Then, you can compile through Eclipse IDE or ’javac.‘ Afterward, you can develop your “.class” files. Although it may not be mandatory, bundling your “.class” is possible and filed into a “.jar” file, where it is executable.
With this, you may opt to share your “.jar” file to Windows, Mac OS, and Linux, and execute it in that file. Occasional confusion is inevitable as you can have various set-up files for different platforms in one Java program. However, all these are not related to Java.
Some apps that depend on specific features use specialized platforms. For these apps, you may bundle your Java “.class” files with libraries for a specific platform.
#3 Effective memory management
With the automatic memory management of Java, this brought a vital benefit for enhancing the online app effectiveness and speed.
In the programming language, memory is classified into two parts such as stack and heap. Basically, the heap has a bigger memory compared to the stack.
Java provides a stack memory for every thread. For a period, a thread can only access its personal stack memory and does include another thread.
The heap keeps the actual objects while the stack variables are used in reference to these. The heap memory is just one in every JVM, sharing it in between threads. However, the heap by itself has several parts that conduct Java garbage collection. The stack and heap sizes are based on the JVM. Below are the various reference types:
Strong. This is the most widely used. It prevents the object in the heap to conduct garbage collection.
Weak. An object found in the heal that has a weak reference to it based on its stack may not be available in the heap following the garbage collection.
Soft. An object available in the heap has a soft reference to it seen in the stack, which is usually left alone. The garbage collection only occurs in case the app runs a low memory.
Phantom. It is only used when the objects are no longer available in the heap and it needs cleaning.
Java works on the garbage collection process instantly, where it pauses all app threads during that time. The process makes use of the references cited above while cleaning up the objects that adhere to specific criteria.
Java puts the other objects side. This whole process is automated. This enables the QA offshore specialists to focus on their business logic, including QA consultation, as they employ the right standards for the needed reference types.
#4 Benefits of multi-threading
With multi-threading, this helps many users to work on one application program all at the same time for their specific tasks. Multi-threading per se is not a new concept. In the case of IBM Customer Information Control System (CICS), this has been widely accepted since the launch of a centralized computing environment.
In the field of the network computing environment, the first programming language was Java, which was introduced to the developers. The uses of Java cover those QA offshore specialists to simultaneously run several tasks with the program, which can have various execution paths.
Multi-threading using Java has several advantages such as:
Responsive servers. Regardless of the allotted time, an approach enables the server to remain responsive with fewer issues.
Quick application response. A Java app runs user inputs instantly despite several concurrent users. Running multiple operations are held simultaneously.
The Java app employs optimally the cache and CPU resources, thus providing improved functionality. The other advantages include reduced development time, handy programming, and low application maintenance costs.
Although testing and debugging methods are shown more complicated with multi-threading, the benefits of multi-threading when used in an enterprise or a mass-usage context is far better and outweighs this potential risk.
#5 Rich Java environment
Among QA offshore specialists and programmers, they are aware of several Java programs such as Eclipse IDE, NetBeans, Maven, and Jenkins. This makes the Java ecosystem to have rich resources.
Some essential resources of the Java ecosystem include the following:
Eclipse IDE. This is considered the best open-source IDE. Eclipse works well with the Java compiler. It exposes compilation errors instantly, provides good facilities for your project organizing, and assists in Git version control. Although Eclipse requires no further introduction, you can read more details by visiting the Eclipse website.
Maven. With this tool, this can help you manage your software. This is mainly used as an enterprise build platform. Maven provides a standardized method to create, test, package, and use your code. Also, it enables you to have proper project documentation. For more details, check the Apache Maven project website.
Spring framework. The main goal for its creation is simply to attain an enterprise Java development. Having its current over a million users, it serves as a leader in the Java server framework sphere. It has multiple useful modules with other open-source frameworks such as Spring Security and Spring Integration.
#6 Java security
For most senior executives or development managers in Enterprise IT companies, they consider security as the very first reason they use Java for backend development. Java faired well compared to other programming languages in securing your app. Using the security model, this spares the Java programs from potentially malicious viruses that users might carelessly download from unverified sources.
Java has no pointers, which makes unauthorized access to memory blocks impossible. Using the Java exception handling concept, managing a series of errors in one go is attainable. In the process, this reduces the possible risk of system failure.
Various JVMs do not run codes in different orders considering Java defines all primitives based on their specific sizes. Also, Java takes the execution order for operations. JVMs always evaluate the Java bytecodes for viruses and malware prior to execution. At the same time, Java enables the developers to use tested reusable codes, minimizing potential risks.
The Java language provides an access-control process to block unauthorized access requests from unverified codes. Finally, Java lets the developers consider classes as “Final,” where nobody can override. This provides guarantees against any hackers.
#7 Presence of skilled personnel
Wherever you are, you are most likely to locate an expert Java developer. This minimizes your labor force risks for development and maintenance. The availability of Java skills anywhere you are gives you the freedom to outsource if necessary.
Uses of Java for your start-up back-end enterprise
In a startup environment, it is possible that some of your developers may seek to choose a trendier programming language such as Ruby on Rails. Keep in mind that Java since its release in the 1990s is evolving to meet the users' ever-changing needs.
The popularity of Java cannot be neglected. It ranks number 1 in several indices such as ’TIOBE Programming Community Index’, ’Indeed Job Keyword Trends’, and ’IEE Language Rankings 2015.′
