Java

7-Nov-12 19:14

I‘ve used C# for one and half years.
Recently,for job reason,I need to use Java.
Actually,I've been learning WP Development,but it is hard to find a job,so I turn to android.
But they are lots of Java and Android books,so any recommend.
Beginner , Advanced Books.

Java in a Nutshell, published by O'Reilly.
The nutshell series are always good value.
A bit of introductory tutorial (more refresher, really) and then comprehensive reference.
So not a beginner's book but a working developer's constant companion.

Cheers,
Peter

Herbert Schildt's Java The Complete Reference

Is it need to learn Java 7 just for android development?

You might not need if you have a grip on the basics of Java. If you have then you can go ahead referring android books.

Hello,

I have a code like this

public class Doc extends DefaultStyledDocument{
}

Doc doc= new Doc();
doc.insertString(0, "This is a working document", null);
AbstractDocument.AbstractElement rootElement = doc.createDefaultRoot();

Once I create a root element how do I assign or set its value from the doc string.Currently the element is blank.

Element root = getDefaultRootElement(); 
Element branchroot = new BranchElement(root, null);
branchroot = createBranchElement(root,null);
Element leafElement = new LeafElement(branchroot, null, 0,0);
leafElement = createLeafElement(branchroot,null,"p");
}


public Element createBranchElement(Element parent,AttributeSet a) 
{
   return super.createBranchElement(parent, a);
}

You could start by giving some more details about your problem. You do not get information from a database just by giving the IP address, but by creating a connection to a database server and making requests, the IP address is just part of the connection string.

One of these days I'm going to think of a really clever signature.

eg input IP,UserName,UserPwd
output database info such as database instance,database user

I have no idea what that is supposed to mean. However, I suggest you spend some time reading about Java Database Access[^].

You are referring to information that is database specific. So you research database specific protocols.

As an example of one such possibility you can look at the following

http://www.sqlmag.com/article/active-directory-service-interfaces-adsi/publishing-sql-server-in-active-directory[^]

And keep in mind that it is possible that one cannot get that information for some databases either because the database doesn't support it or because it is not published. That of course suggests that the best way and certainly the easiest is to just require that the user must provide that information.

Please develop a simple console base application, which reads some persons records from a “.txt” file and displays each person’s information in form of table. The program should also count and display the number of alphabets, spaces, integers, words, characters and lines from the file in tabular form.
please make this application file (.java) and driver file (.java) separately.
(All three files will be in one folder for execution through driver file)
