1)need to read the data from an input file where input file contains parameters like no:of nodes,no:of subgraphs,random number etc.(idea how to specify all these in input file)
2)create a data structure tree or array to store above
3)create graph in main memory and traverse this graph a node at a time and outputs the data into output files
4)output file must contain node id and ids to which it is connected to
please help.i am starter in coding.please do help and guide me.thanks in advance.

0) Please do not use bold characters, it appears as if you are shouting, and that is considered rude.
1-4) First learn Java and its libraries: http://download.oracle.com/javase/tutorial/index.html[^].
5) People here are happy to help you when you get stuck with the code you have written, but no one is going to write it for you.
yes, I agreed bu problem is that to shared variable of my current running application to other java application and if other application access my class that is OK but how to share value of my current running object.
I am a beginner for Java programming. I started to self study by referring java documentation. But it is too complicated. But I followed language basics. After that I am in a trouble to select that , which java technologies to study. My dream is to be a java developer. Anyone can guide me?

Presumably you have in fact managed to create some simple programs and now you have reached the point where you want to study some part of java without attempting to learn everything at once.
If you like pretty pictures you can learn swing although you probably shouldn't spend too much time on that since most new development won't use that. Despite that learning the basics of graphics can still be helpful. And it is possible that you will encounter this at some point.
Alternatively to that is you could learn how sockets work. Build a chat program (swing could help with that but not necessary.)
What is the best way to structure the naming of your (java) packages?
By design paradigm: my.app.dao, my.app.services, my.app.util, my.app.model, etc.
or by function/context name: my.app.clients, my.app.registration, my.app.production, my.app.accountancy?
On a side note:
I think I remember watching a keynote speech on the Spring framework where a developer advocated the structuring of packages according to the application's domain functions. The same would happen for URLs:
Not exactly sure what you are suggesting but if your 'services/userregistration' is based on authorization/authentication then you have a rest call for that and nothing else. Presuming that the functionality is in fact the same.
That is similar to your other areas in that either something like 'products' is different for 'model' and 'services' or it is the same. If the same then there would be a root 'product' and not the way you broke it out. If they are different then they should have two different rest methods.
I'm not sure i'm in the right topic for this question. Feel free to redirect me to the appropriate one, if necessary.
I have an ANT related problem. I want to read some values from a file (new.txt), substring the parts i need from each line and then, concatenate all these values with "_" between them. This big concatenated string will be the name of a folder i'll create. Here is the code i wrote:
var text = attributes.get("text");
var end = text.length();
var start = attributes.get("start")||text.lastIndexOf("=")+2;
project.setProperty(attributes.get("property"), text.substring(start, end));
I want something like: 1344_dvfgf_sfgg_wfggh
but i have: _1344_dvfgf_sfgg_wfggh
The Alert Interface in Selenium doesnt have any implementing classes on its own. In such a case, how will the user get to know the exact method or exact class through which the alert interface can be used....
To put it in a simple way, how to use an interface when there are no implementing classes for the interface.
Hi,all.Could anybody give me a detail describtion of the channel?(that is,something likes file channel,socket channel,etc.) or give me the relative link about it.Also,I want to know:
1.How the os implements the channel,does it need any hardwares to support?
2.What does it differ from the stream,in what situation,I should use it rather then the stream? What's its advantage?
Thanks to all.
Please take file channel as an example to explain it,mainly focusing on thease questions:
1.How the os implements the file channel,does it need any hardwares to support? or it just a virtual concept?
2.Why I should use it instead of the file stream?
The Channel[^] is a Java concept, implemented on top of the operating system. As the documentation states, this can be a hardware device, a file, a network socket, or a program component that is capable of performing one or more distinct I/O operations, for example reading or writing. The choice of when to use channels over streams is something you need to decide when designing your application, as it will depend on your requirements.
I am developing a java application which after developing i want to sell off to some organisation, but i dont know how to package all my project files into one file for commercial because i dont think they need to be viewing my source code.
How can i pack them all in one setup file? :(
The simplest way is to put all your classes into a java archive via the jar command. You then need to send only the jar file(s) to your customers; see http://docs.oracle.com/javase/tutorial/deployment/index.html[^]. You could also try a Google search to see if there are any other setup applications applicable to Java apps.
