There are relatively few devices that don't have a JVM implementation, but it is not true that all devices should have a JVM.
Yes. Apart from lower grade mobiles which have no support for java, java written codes can execute on all platforms and all devices.
JAVA Application is the software which provides special games for the mobiles .its centre is at all states of India
Yes. All computers and laptops can run and support Java. You can download Java from Sun's website and then install it in your computer to use it.
You never really need a Java application on your PC. If you don't want them, don't install them.
All major servers like Weblogic, Webspher, Tomcat support Java Platform
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?
Servlets serve as the central point of control of a J2EE application. It contains all the processing and control logic of the application.
Java applets are programs which we can embed in a webpage. It will act from server to client machine. But java can be used to make stand alone programs also. These programs will include games, freewares and all.
Java is a programming language originally developed by Sun Microsystems and released in 1995 as a core component of Sun's Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode which can run on any Java virtual machine (JVM) regardless of computer architecture. There were five primary goals in the creation of the Java language. It should use the object-oriented programming methodology. # It should allow the same program to be executed on multiple operating systems. # It should contain built-in support for using computer networks. # It should be designed to execute code from remote sources securely. # It should be easy to use by selecting what were considered the good parts of other object-oriented languages.
Exception handling should be used in Java in all cases where you as a programmer suspect that your code might throw some exceptions or create errors that might look ugly when a user is using the application. In such cases you use exception handling to catch and handle the exception and exit gracefully. You use the try - catch block in Java for exception handling.
If you mean the devices in your house that are connected to the internet, there is no need to download an application. If you type your IP (Internet Protocol) address into your internet browser, you can see all the devices that are connected to your router. Just simply log into it and there you go. Be sure not to mess with anything in your routers settings though.
If you want to play it, then go ahead! The game was written in Java, so all you need is the Java VM, acquired when you install Java.
