Q7. Does Oracle develop Java??

Yes, Java was developed by Oracle. And, for the past many years, it has been used for developing countless applications of different types ranging from simple to highly sophisticated ones.

Moreover, It has been the primary language for developing Android apps, resulting in the immense popularity of Java programming among developers. Besides, it is also the most preferred language for developing cross-platform apps.

However, it is worth mentioning here that Sun Microsystems had developed the original version of Java. On 27th September 2010, Oracle Corporation announced its acquisition of Sun Microsystems, after which it continued the development of Java under the banner of 'Java SE.'

Q8. Who owns Java now??

Developed by Sun Microsystems, Java has been acquired by Oracle Corporation. In 2010, Sun was acquired by Oracle for US $7.4 billion.  As part of that deal, Oracle became responsible for Java and several other critical pieces of software development and hardware engineering under a new organization called Oracle America, which is headquartered in Redwood Shores, California (USA).

Because Oracle could not include Java within its corporate name due to trademark issues (unrelated entities already trademarked the name), it named its Java subsidiary Oracle America. Currently, Java is on version Java 17.

Q9. What is Java used for??

Java is a powerful object-oriented programming language that can be run on various systems, including Windows, Mac OS X, and Unix. Its primary use is to develop applications for Web-based applications and enterprise applications. When you’re searching for a Java development company, make sure to look for those with expertise in e-commerce, business intelligence, and databases. 

Java developers are also often responsible for handling maintenance on existing Java codebases and creating documentation so other team members know how things work. Because Java has been around since 1995, there are lots of libraries available for it. Still, by sticking to well-established libraries and frameworks (rather than creating your own), you help your team doesn’t experience unforeseen problems.

Q10. Who built Java??

The first version of the language, called Oak, was designed for interactive television set-top boxes. After failing to push that iteration of the language forward at AT&T and Novell, Gosling brought it with him to Sun Microsystems (after a short stint at Silicon Graphics), where he and Mike Sheridan revised it into what would eventually become Java.

On December 9, 1995, Sun released its first public implementation as "Java 1.0". The development of Java made sense because it used to write once, run anywhere (WORA) technology that could be portable among any computing platform if appropriately compiled. Every year since then, a new version of Java has been released that is more secure and powerful than the last one.

Q11. How does Java work??

Java is pretty complex, but it basically works in two steps:

  • Compilation step to Java bytecode
  • Execution step loading the bytecode in memory and executing it.

Java applications are compiled to Java bytecode, which is then run on a Java Virtual Machine. A few key insights are essential here: The JVM doesn’t know or care what kind of machine it’s running on, and it just knows how to execute bytecode. That means you can write your application once and run it anywhere.

And, because of that portability, you have access to a vast range of libraries, tools, and other resources that will help you build amazing apps quickly. Java was built for server-side development, but there has been an ongoing debate over whether it should be used for client-side development since its inception.

Further, regardless of where you stand on that issue, there are some great reasons why any developer should learn Java like the back of their hand. For example, it’s still the number one language for enterprise development on the JVM, and it also remains the language of choice for Android development. And it’s used as a backend programming language for many popular web frameworks like Spring and Play.

Q12. What is a Java interpreter used for??

Sun Microsystems created a programming language called Java. To use Java, you need a computer program that translates code from a high-level programming language into something that a computer can understand. A piece of software called an interpreter is used for precisely that purpose: It takes a piece of high-level code and translates it into commands that can be executed by hardware or directly translated into machine code for execution by CPU.

This interpretation step gives a performance benefit over traditional compilers because it doesn’t have to do everything at once; instead, interpreting only has to translate one instruction at a time before executing it. Java interpreters are typically tiny—and thus run fast—because they’re not responsible for doing anything but translating instructions one at a time.

Q13. What are the advantages of using Java??

Some of the exciting benefits of using Java include:

  • Multi-threading. It supports multithreading which implies a single application can run multiple threads at one time. This way, it facilitates the faster execution of an application. 
  • Garbage Collection. It automatically manages the memory allocation and de-allocates when not needed, thus helps in avoiding memory leaks. The size of an application is smaller than other programming languages.
  • It supports Object-Oriented Programming ( OOP ). The code developed in the OOP is reusable, which reduces a large amount of coding effort and time. For a massive project, this feature proves quite beneficial.
  • Java has a vast network of libraries to offer plenty of features. Developers can use these features for developing their applications without writing too much code from scratch.
  • Secure. It ensures the security of the entire system and restricts access to any unauthorized entities.

Q14. What major companies use Java??

As of now, most of the programming languages are compatible with Java, which is why many organizations are extensively using it to develop some great applications. Some major companies that have adopted this secure and reliable technology for their businesses include Twitter, Amazon, Tesla Motors, PayPal, Walmart Labs, Cisco Systems, etc.

Q15. Can Java be used for software development??

Yes, Java can develop software solutions for several industries such as Media & Entertainment, Travel & Tourism, Education, Gaming & Gambling, Finance, Banking, etc. Various organizations around the globe are using it.

Java is a robust, secure, and object-oriented programming language created in the early 1990s. In simple words, it can be said that Java provides a platform for developing cross-platform mobile applications.

It has been widely used for mobile application development for the last 25 years due to its simplicity, ease of deployment, and security features.

Q16. Is Java Web development in demand??

Yes, Java is widely used for developing web-based solutions. It powers many websites and serves as the backbone for some leading platforms, including Android, Big Data, Cloud Computing, etc. Besides,  it also comprises many community-based platforms such as JBoss, GlassFish, Apache Tomcat, etc.

Q17. What do Java developers do??

Java developers are responsible for the development of applications based on this technology. They use their knowledge and experience in writing, testing, and debugging codes to develop high-quality applications in eCommerce, HealthCare & Pharmaceuticals, Manufacturing & Automotive, IT & Telecom, etc.

Q18. Is Java front end or backend??

Java is a back-end programming language and helps in building the server-side part of an application. It can be used to develop web and mobile applications.

It is an Object-Oriented Programming (OOP) language, and it is primarily meant to be compiled into bytecodes. These bytecodes are then executed by the Java Virtual Machine (JVM). It can also be run anywhere using the "Java Runtime Environment" or JRE. You can also work in this language if you have a background in C, C++, or any other low-level programming language. It is mainly used in the IT industry for building enterprise applications and embedded components.

Q19. How do I install Java??

Java is compatible with all the operating systems and can easily be installed on a system. You can visit Oracle's official website to download the latest version of Java for your OS. Once you have completed the installation process, check if it is working correctly by opening a new Command Prompt or Terminal window and entering the following command:

java -version

If the Java path is displayed, then it means that the installation was successful. If the error "The program Java can be found in the following packages" is displayed, then follow these steps to set up your path correctly.

Q20. How many types of compilers are there in Java??

There are two types of compilers available for Java:

  • JIT (Just-In-Time) Compiler, which is also known as the client compiler. The JIT compiler translates bytecode to machine code during runtime. The advantage of using the JIT compiler is that it speeds up the program execution.
  • AOT (Ahead-Of-Time) Compiler, which is also known as the server compiler. The AOT compiler converts bytecode to machine code before running a program. Since all the steps are carried out beforehand, there are fewer chances of errors appearing.

Q21. Which is better, Java or Python??

Python is a dynamically typed language, whereas Java is a statically-typed language. The static typing feature of the latter makes it more efficient and effective since the errors are found during compilation itself which further helps in debugging, code optimization, etc. Apart from that, Python codes comparatively slower than Java which means that you cannot expect too much from it when it comes to performance.

Q22. Where can I hire a Java developer??

You have numerous sites and options where you can find Java developers. Some of the popular options include Authentic Jobs, Elance,,, etc. You can also post your requirements on Facebook groups and mailing lists and wait for the interested developers to contact you with their proposals. You can even check our website-SoftwareFirms to find the best software development companies, mobile application development companies, WordPress development companies, etc.

Q23. What are the different types of Java developers??

There are generally three types of Java developers: Junior, Mid-level, and Senior. Depending on their designation, they have to be skilled in various technologies, which can further help them settle down in a particular field within the organization. Every Java software developer needs to acquire the required skill set to stay ahead of their competitors.

Q24. How much does it cost to hire a Java developer??

The cost varies from industry to industry and mainly depends on the experience of the Java developer. It also depends on the level of the skill set required for a particular project and how challenging it is. Many factors contribute to determining the salary structure of a Java developer, which include the kind of company, location, etc. As a thumb rule, you can expect to pay anywhere between $50/hr and $75/hr for a good Java developer.
