"Platform neutral" means that Java does not depend directly on the underlying operating system; the same binary Java classes will run on any platform that support the target version of Java that those classes use, such as Windows, Linux, and Mac OS.
Java has enhanced security opposed to a native binary (e.g. a program written in C++) in the sense that an additional layer of security is implemented in the Java VM that reduces promiscuous behavior (such as accessing the hard drive when running as an applet). Java is arguably not as secure as some other languages (such as Mono/.NET, which can be statically verified safe without executing the program), but it is generally more secure than non-VM-based languages because of the extra layer of security.
What is servlet cookies in java programming?
a small amount of information sent by a servlet to a Web browser, saved by the browser, and later sent back to the server. A cookie's value can uniquely identify a client, so cookies are commonly used for session management.
A cookie has a name, a single value, and optional attributes such as a comment, path and domain qualifiers, a maximum age, and a version number. Some Web browsers have bugs in how they handle the optional attributes, so use them sparingly to improve the interoperability of your servlets.
The servlet sends cookies to the browser by using the HttpServletResponse.addCookie(javax.servlet.http.Cookie) method, which adds fields to HTTP response headers to send cookies to the browser, one at a time. The browser is expected to support 20 cookies for each Web server, 300 cookies total, and may limit cookie size to 4 KB each.
The browser returns cookies to the servlet by adding fields to HTTP request headers. Cookies can be retrieved from a request by using the HttpServletRequest.getCookies() method. Several cookies might have the same name but different path attributes.
Cookies affect the caching of the Web pages that use them. HTTP 1.0 does not cache pages that use cookies created with this class. This class does not support the cache control defined with HTTP 1.1.
What will happen if a String array is not provided as the argument to the main method in Java EE?
java takes command line arguments from user so as to execute the program,that's why we always mention arguments for main() , now java always assumes that the argumetns are of String type which may be appropriately converted to any other type later. that is why we pass string array to hold the command line argumetns supplied by the user.

What is pure object oriented language?
Object-oriented (OO) applications can be written in either conventional languages or OOPLs, but they are much easier to write in languages especially designed for OO programming. OO language experts divide OOPLs into two categories, hybrid languages and pure OO languages. Hybrid languages are based on some non-OO model that has been enhanced with OO concepts. C++ (a superset of C), Ada 95, and CLOS (an object-enhanced version of LISP) are hybrid languages. Pure OO languages are based entirely on OO principles; Smalltalk, Eiffel, Java, and Simula are pure OO languages.
Reference: Tokar, Joyce L. "Ada 95: The Language for the 90's and Beyond."
" According to me JAVA is not a pure oop Language ,because java contains primitive datatypes that's not an Objects."

How do you find missing numbers in a array with elements below its size?
Please rephrase your question. An array usually has a fixed size and I don't recall ever having to "go below its size". This implies that the missing elements are not within the range of the array.
Where can you find roms for java games?
A ROM image for a video game is basically a software copy of a hardware chip. There is no such thing for Java, or any game written in Java.
What is main advantage of using constructors in java?
Constructors have the same name as the class itself and they do not specify a return type, not even void because they return the instance of the class itself.
Because constructors have the same name as the class then they allow method overloading and also save memory and execution time of program.
Program release memory of constructors function after using this function and it reduce program complexity.
Why are Inheritance super classes fragile?
Superclasses are considered fragile because seemingly safe modifications to a super class, when inherited by the derived classes, may cause the derived classes to malfunction.

What is a return statement used for?
It means end the function. Functions automatically end when execution reaches the end of the function, but you can return from a function at any point within the function with a return statement.
If the function returns a value to its caller, you must provide a reachable return statement along with the value you wish to return.
