<div>
<br />
010 is octal ten as it starts with zero, means it is decimal 8 or binary 1000<br />
<br />
4 is binary 100 <br />
<br />
now when you make bitwise or 1000 with 100 you end up with 1100 which will be 8 + 4 = 12<br />

How to know the number orignally in which mode like octal, binary, decimal, Hex etc. Then<br />
how we know we have to convert to binary before adding when there are 10 different modes like Hex, Octal etc all. please advise

I read above question from link<br />
<a href="http://www.jchq.net/certkey/0503certkey.htm" rel="ugc">http://www.jchq.net/certkey/0503certkey.htm</a><br />
i did not understand how 12 is answer and how octal is related here.<br />
<br />
<br />
<br />
Any ideas, resources,sample code,links, &nbsp;highly appreciated. thanks in advance.<br />

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Java

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.

Java EE

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.
