JAVA

Java is a programming language that was developed by Sun Microsystems. It is similar to C++, but eliminates all the features which results in common programming errors. The java source code files having .java extension are compiled into bytecode having .class extensions which are executed by java interpreter. Java compiled code can run on any computer because the java run time environment and interpreters, known as JVM (Java Virtual Machines) are available for most of the OS.

Some Features of Java are as follows:

a)      Platform Independent: The concept of Write Once and Run Anywhere is a very important feature of Java. A compiled java code can run on any computer/platform required the platform must contain JVM.

b)      Simple

c)      Object Oriented

d)     Robust

e)      Distributed

f)       Portable

g)      Dynamic

h)      Secure

i)        Multithreaded

 

Programming in Java Script

 Java Script is very easy to use programming language which can be embedded in the header of our web page. It makes our web page interactive and enhances the dynamics of our web page. It helps us perform calculations, write interactive games, create security passwords, add special effects, check forms etc.

Difference between Java and Java Script

Java is a technically interpreted language which is coded similar to C++ and is compiled before the execution. It is powerful enough to create major applications and is also inserted in the web page as an object called “Applet”. It is not considered as an easy language for non programmers.

Java Script as said before is a very simple language. If we would like to check form for errors, we just need to type an if-then statement at the top of our page. No applets, no compiling, but just a simple sequence.
