You should know C and C++
Of course not.
The original plan was to call the Java language "Oak", but it turned out there already was a programming language of that name, so they changed the name. Java is of course unrelated to this other "Oak" language, the one that had already reserved the name.
I took a Introduction to Java course last year. I had the same question when I started the class http://www.DevelopIntelligence.com/catalogue/java-training.php. But I learned that Java and .NET are both platforms that run applications. Both platforms use something known as a virtual machine. In the Java platform, the primary programming language use to write applications is called Java. In the .NET platform, the programming language choices include VB.NET, C++.NET, C#.NET. In other words, there is no "difference between the Java langage and the .net language" as there is no "net language". The Java language is most similar to the C# language in .NET. There are some technical differences, but in general they are about the same.
Java is an Object Oriented language not a procedural language
No. Java (a programming language), is not a prerequisite for learning how to use any mainstream operating system (such as Windows, Mac OS, or Linux).
Yes!Visual Java plus plus and Java Builder is different from the Java language?
We need to take Java courses because Java is a main stream subject for engineering courses in computers and information technology (IT). These courses mainly focus on building a basic idea and implementation of the language.
java is platform independent language and open source. java is object oriented language.
java language moreover solve the problems witch is encounter in c and c++ that s why we use the java language...
Java is truly object oriented programming language
"Java Tutorials" contains a very complete answer to this question. The explanation is too long to contain as an answer in this question. Refer to this website for the code necessary to do that.
It is not necessary to learn HTML before learning Java. Java is a complete computer programming language. The only reason you would need to know HTML with Java is if you wanted to use Java to generate webpages, or you wanted to create Java applets that you would then embed into webpages using HTML.
