Are you asking us to review your code, rewrite it for you, or give you an algorithm for how a balanced binary tree should work?
|
|
|
|
|
Review the code, of course. Then rewrite the code(with comments possibly, so I can understand it better) which is a big time request. I am struggling big time with it. Please assist me.
|
|
|
|
|
can you answer me:
How do you define the Binary Seach Tree(BST)?
if you define by List Link you can repair struct of two tree:
step 1: find possible of root of tree 2 in tree 1;
step 2: replace link at this possible
step 3: ok;

Please format that mess as a "code block" - no one is willing to read this otherwise.
Where is the problem? did you debug it?
I never finish anyth...

|

Okie! I'm formated code, please you help me ?
|
|
|
|

great. Please feel free to provide more information as you also want some lines as answer.
- where at Yahoo are you trying to login? mail? social stuff? other?
- what kind of exception did you get? Post the exception!

Exception:
{"error":{"lang":"en-US","description":"Please provide valid credentials. OAuth oauth_problem=\"signature_invalid\", realm=\"yahooapis.com\""}}
Here, I'm used Yahoo API get profile information of user. Frist I'm get request token, after I'm used request token get access token and parameter, final I'm used access token and parameter get profile of user. but I've encountered one bug \"signature_invalid\" in the final step.

see - the exception says:
Please provide valid credentials
so please check them. It's not fun, but they are broke.

This sounds a rather specific problem. You might find asking on a yahoo API programmers' forum that you'll get more help.

Point 1: use the proper <pre> tags to format your code rather than the inline <code> tags (go back and edit your original message).
Point 2: Nobody is going to download your project in order to find out what's wrong with your code. Compile and test your program, find out what or where it is going wrong, and post a proper description of your problem; people will then try to help you.
The best things in life are not things.

Hi folks!
this is the code thats giving me problems.
try{
ResultSet rs = Main.dbase.search("select * from myTable");
while(rs.next())
{
cmb.addItem(rs.getString(1).trim());
}
rs.close();
} catch (Exception ex) {System.out.println(ex);}
here dbase is an object executing Statement.executeQuery, and cmb is JComboBox.
the problem is that even though the table has 10 rows, i get only single row in cmb.
if I don't comment out the first rs.next(), i get the 2nd row in cmb.
i tried to track the value of rs.next() and found that after while(rs.next()) it gives out false, always.
My target is to get all the 10 values in cmb.

Have a go at this:
Statement statement = null;
try {
statement = Main.dbase.createStatement();
ResultSet rs = statement.executeQuery("select * from myTable");
while (rs.next()) {
cmb.addItem(rs.getString(1).trim());
}
} catch (SQLException e ) {
System.out.println(ex);
} finally {
if (statement != null) {
statement.close();
}
}

So you are agreeing that it does not in fact answer the question?
|
|
|
|
|
There are two parts.
1. Database code
2. Gui code.
It seems apparent that you are in fact getting 10 rows from the database. Your statements about the commented rs.next() and your implicit comments about it.
If you are not sure the verify it using a debugger or System.out.println (do NOT use gui code.)
Consequently that means the problem is with your GUI code and not the database code.
You can replace your database code entirely with a for/next loop that adds 10 fixed values (such as "xxx") to the combo box. Until that code works it is pointless to attempt to do anything with the database code.
Creating a small complete example with JUST the gui code (no database code) might help to determine what the problem is.
