The object-oriented model is based on the idea that objects exist independently of one another, and that operations can be performed on them. Consequently, the user in a real object oriented development environment must be able to interactively create objects of any available class, manipulate these objects and invoke user interface actions. Independence of the platform – " Type once – play anywhere Possibility
In fact, you cannot run the Java program anywhere 'unless there is a virtual machine. But as good as anywhere. I also know some people who say "write once Corrected everywhere "But such platform-based errors can be a problem with VM. Everyone in all of this platform is a great point of approval for enterprise development to save a lot of money and effort in moving products.
Ease of use
I'm not really sure how many good programmers agree with me, but it's easy to visualize software when it's object oriented (once it crashes). After building the concept, it becomes easier to understand it in the code
Free runtime / compilers / tools
This was one of the best moves ever made. Runtime is free, development kit is free, and there are now lots of other tools created with java for java for free. This makes Java Development easy and affordable.
There are a number of ways to measure the popularity of a programming language, for example, based on a number:
- New applications written in the language
- Existing applications written in the language
- Developers who primarily use the language
- Developers who use language ever
- Internet searches
- Available jobs that require language skills
- My favorite developers
Java has some other advantages as a language of instruction
• Low cost. Tools to build and test Java programs
Available without charge. Sun provides an online Java (JDK) development kit, where faculty and students alike can download it. JDK – which includes a Java compiler and compiler, among other tools – is recognized as austere, but students must find it appropriate for most programming tasks. Those who want to spend a little money will find better software development environments (such as Symantec Café and Microsoft J ++) available at moderate prices.
• Easy to test. Students can put their programs – written as small apps – on their webpages for test and critic coaches. Coaches can monitor student progress at any stage by just visiting the student's webpage.
• Student enthusiasm. Java got a lot of publicity
Students must be eager to learn this. By harnessing this enthusiasm, coaches can use Java as a way to teach students an enormous amount of modern computing. Students will be motivated by the growing importance of Java in the "real world". Moreover, students will be happy with the ease with which they can build advanced GUI software.
• Suitable for advanced courses. After winning students
Familiarity with the basic features of Java in CS1, they can use its advanced features in later courses. For example, an OS course can benefit from Java Thread Support. The network classes that come with Java make it ideal for the networking cycle.
• Ease of transition to C ++ and other languages. C and C ++ Java similarities should make it easier to transition to these languages.
• International call. The Unicode character set is an integral part of Java, allowing students to learn about software development issues for the international market.
Java has important advantages not only as a commercial language but also as a language of instruction. Lets students learn object oriented programming without exposing them to the complexity of C ++.
