Java Courses

Oracle, the owner of the Java programming language, has the Oracle Certified Developer: Java SE 11 Developer program, which is easily the best certification to obtain for Java developers. The main reason why it’s the best certification, is, unlike most other certifications for Java, the Oracle certification is both well known and universally accepted by employers all over the world. The exam is challenging. You also must bring an ID with you to the exam, so you cannot get anyone to take it for you. Certification is really valuable for both the certification holder and for future employers. There are few, if any, other certification programs so universally accepted as Oracle’s Java certification. Thus, getting Java certification is one of the surest ways to give yourself an advantage over other job seekers in the marketplace.

Java is a very popular language and has been for over 20 years. Because of its popularity, it’s built up a huge range of frameworks, toolkits, tutorials, and support. Not to mention, Java developers have a huge number of career opportunities. Another pro of Java is platform independence. A wide variety of computer hardware and operating systems can use Java. Java is also relatively easy to learn and relatively secure. Java runs on its own virtual machine, via byte-code. When compared to traditional languages like C++ that compile to native machine code, Java’s performance can be slower for applications that are time-critical. Java code is verbose and requires much more code to achieve the same functionality compared to languages such as Python. Overall, developers will likely continue to use Java for many years to come because of its popularity and huge adoption.

It’s always difficult to advise someone which language to learn first. Any decision should be based on your longer-term goals. Do you want to learn a language, fast? If so, Python is probably quicker to learn; it has less formality and is often just more fun to learn. Are you coming from another programming language like C# or C++? If so, Java is similar, so you would probably learn Java faster compared to a language like Python, which does things very differently. For example, Python has indentation instead of curly braces. The choice of Java vs Python might come down to the languages’ ability to meet certain goals. For example, if you want to create an Android application, Java is best. Python is not used to write Android applications. Both languages are very popular, offer great career opportunities, and you can learn either in a relatively short period of time.

When comparing the top three Java IDEs — Eclipse, NetBeans, and IntelliJ IDEA — NetBeans tends to be the strongest all-around candidate. First released in 1997, it has a significant body of documentation and a thriving community. You can easily develop mobile, desktop, and web applications with the help of its cross-platform support and visual debugger. Ultimately, though, the best IDE is whichever you're most comfortable using. Many developers prefer to use Eclipse or IntelliJ IDEA because their tools better-align with their workflow. For instance, Eclipse supports application development for a variety of languages through plugins. It also has advanced features for reporting, charting, modeling, and testing. IntelliJ IDEA has both a licensed version and a proprietary commercial version. It has some advanced, powerful features like data flow analysis and cross-language refactoring, but it will also be more expensive than Eclipse or NetBeans.

Java and JavaScript don’t have a lot in common, apart from the word Java. They are different languages, each with strengths and weaknesses. Netscape created JavaScript in 1996. Sun Microsystems created Java in 1991, with the first version released in 1995. Netscape then added Java to the name JavaScript as a marketing ploy to piggyback on the success of the Java language. JavaScript is primarily used in a web browser to make web pages more interactive (web-based applications) whereas Java is used to create standalone applications to run on single computers and servers. Both languages share a similar syntax based on C, but JavaScript is a lightweight language and Java is an object-oriented language with its own virtual machine.
