One may learn about Java concurrency in the book 'Java concurrency in practice' which can be purchased from various online retailers. Additionally, Java concurrency is often discussed in various formal training classes.
There are many places where one could find advice about working with Java sorting arrays. The best place to learn more about working with Java would be to contact Oracle.
Basically both are good at their places, can't be interchanged. But Java is best if we compare both because Java is much more secure, robust and portable as compared to C++ as a Java program is first converted to byte code and then interpreted. Also C++ program is compiled all at once but Java program is interpreted one instruction at a time thus making it more secure .
No and it is up to you to decide. (You asked two questions in one, so you got two answers in one.)
No. There can be multiple java classes in the same .java file, but the name of the file must match the name of the public class in the file.
One can find freelancing jobs in the Java writing field on the Freelancer website. One can also visit the CWJobs and the Jobsite websites to find Java related jobs in the UK.
One could find more information about the Java Virtual Machine online on various websites such as 'Wikipedia', 'Java-Virtual-Machine' and of course the website 'Java'.
If I understand your question, they are similar because one language came from the other.
There are many places one can look for jobs using Job Centre Plus. Examples of places where one can look for jobs using Job Centre Plus includes areas in the United Kingdom.
Currently the IT industry is going through the best phase that it has ever seen. This scenario is expected to continue for the next one decade at least. The best java jobs will obviously be found where there is a cluster of IT companies. In India, these locations are Pune, Bangalore, Hyderabad, Chennai and Delhi/NCR. These locations have the best java jobs because they have the best IT and technology companies based out of there.
In java we can implement more than one interfaces for a single class but we can't extend a class to more than one super class so ,java indirectly supports multiple inheritance.
It depends. Look around at the job postings for jobs that you'd like at some point in the future. Do they want C++ or Java? I'd pick the one the best lines up with the jobs you may want in the future. Both programming languages are widely used, so there's nothing wrong with choosing either. As a professional in the field, I can tell you that it is important to BOTH know a programming language really really well, and also, have a good understanding of multiple languages. A good programmer will know four or five languages well.
One can find more information JAVA xml from websites like MK Yong, Vogella, Developer Fusion, NTU, Seas, Tutorials Point, Java World, Cafe Conleche and JCP.
The Core Java technologies and application programming interfaces (APIs) are the foundation of the Java Platform, Standard Edition (Java SE). They are used in all classes of Java programming, from desktop applications to Java EE applications. Well What exactly you mean by Java?
Programming languages are usually good at certain types of tasks. Moving from one language to another is usually dictated by the task that you need to perform. For networking and portability tasks Java does a good job; in certain other tasks, especially those that are computationally intensive it might make more sense to use c plus plus. So, it isn't a matter of why someone moved from one language to another, but more a function of which language (of the hundreds or thousands available) performs the solution in a better manner.
Lots of companies need computer programmers, and in many cases, they need people who know Java. Note that a one-semester course in Java may not be enough; you may need to learn more advanced Java, depending on the job.You can search job sites, such as upwork.com (a site for freelancers), for the keyword "Java", to get a better idea of available jobs.
