How to change the values of spinner and radio button if I click on a row from jtable (must depend on the values form jtable)

If I click a row(JTABLE), it must display the specific values back to the textfields/combobox/radiobutton/spinner. But in my case, it's just hard to retrieve the values back to the RADIO BUTTON and SPINNER.

How to change the values of spinner and radio button
The spinner should be easily settable by calling its setValue(...) method, and passing in the number from the selected table row item.
For the JRadioButtons, probably the easiest solution is to use a Map that maps the selection to its radio button, and then using this map to get a reference to the proper JRadioButton, and calling setSelected(true) on it.
For an example, and for an example of a Minimal, Complete, and Verifiable example, please have a look at:

But I don't know how to apply this to the password that the user enters so that when the password is entered into the database here
String sql = "INSERT INTO Registration (username, Password, businessName, typeofBusiness, email, contactnumber, address, Employed) VALUES (?, ?, ?, ?, ?, ?, ?, ?)";
PreparedStatement statement = conn.prepareStatement(sql);

if (rowsInserted > 0) {
final JDialog dialog = new JDialog();
dialog.setAlwaysOnTop(true);
JOptionPane.showMessageDialog(dialog, "A new user has been added successfully");
}
}
The password stored would be the encrypted password

Instead use an itererated HMAC, functions that do this include PBKDF2, password_hash, bcrypt, etc.
Notes:
Do not use Random with the time as a seed, to get a seed, use the cryptographic CPRNG: java.security.SecureRandom, it does not need to be seeded.
Do not use MD5 (attackers love it).
Hasing is not encryption, it is a one-way function, encryption is a two-way (it can be decrypted).

statement.setString(2, encrypt(PasswordTextField.getText()));

Can you call Registration.encrypt(PasswordTextField.getText()) when setting the strings?
Also, nitpick: the password is (and should be) being hashed, not encrypted. Encryption implies it can be decrypted.

Strange NullPointerException in Java Client-Server program

I am creating a 2 player game in which clients receive 2 Strings from the server and have to respond with a String of their own. The internal processing is irrelevant here. The main thing is, whenever I send data from server, one of the clients ends up showing a NullPointerException for a setText() function. I am baffled as nobody else at my university knows the reason for that. Please help me solve this issue.
Here is the code (the IDE is NetBeans 7.3.1):
Server
public class TCPServer {
public static void main(String argv[]) throws Exception {
String childWord, childWord2;
Trie1 obj = new Trie1();
obj.loadTrie();
ServerSocket welcomeSocket = new ServerSocket(6759);
ServerSocket welcomeSocket2 = new ServerSocket(6559);
//BufferedReader dd = new BufferedReader(new InputStreamReader(System.in));
String parentWord;
while (true) {
Socket connectionSocket = welcomeSocket.accept();
Socket connectionSocket2 = welcomeSocket2.accept();
//parentWord = dd.readLine();
parentWord = GlobalStuff.word;
System.out.println("word: "+parentWord);
BufferedReader inFromClient =
new BufferedReader(new InputStreamReader(connectionSocket.getInputStream()));
DataOutputStream outToClient =
new DataOutputStream(connectionSocket.getOutputStream());
BufferedReader inFromClient2 =
new BufferedReader(new InputStreamReader(connectionSocket2.getInputStream()));
DataOutputStream outToClient2 =
new DataOutputStream(connectionSocket2.getOutputStream());
outToClient.writeBytes(parentWord + "\n");
outToClient2.writeBytes(parentWord + "\n");
outToClient.writeBytes(GlobalStuff.sentence + "\n");
outToClient2.writeBytes(GlobalStuff.sentence + "\n");
childWord = inFromClient.readLine();
childWord2 = inFromClient2.readLine();
/*System.out.println(childWord);
System.out.println(childWord2);*/
//System.out.println(clientSentence);
if (childWord.equals(childWord2)) {
System.out.println("The suggestions match!!");
obj.Trie1Main(parentWord, childWord);
} else {
System.out.println("The suggestions DO NOT match...the users entered:");
System.out.println(childWord+" and "+childWord2);
}
}
}
}

This is the Exception
This is supposed to be the output if the client runs correctly
Line 272 in the error message is hword.setText(modifiedWord)

So this means that hword is null and you have to ensure it has been initialised before you call this method.
Any update to the GUI should be performed on the GUI thread in any case. I suggest you submit a task to perform the update. This way it should be initialised by the time you use it.
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
hword.setText(modifiedWord);
}
});
What you should be doing though, is calling this method on the Player1 instance instead of setting a static field. You really shouldn't be initialising static fields in a constructor.
Player1 player1 = new Player1();
EventQueue.invokeLater(() -> player1.setVisible(true));
EventQueue.invokeLater(() -> player1.setHwordText(modifiedWord));
This way you don't need the static fields.

Java Netbeans For loop error: cannot find symbol class, <identifier> expected?

I'm making a hangman game and this is my current code:
//Declaring the array
String [] WordList = {"anonymous", "tolerate", "appreciation", "commissioner", "harm", "flexibility", "instructional", "scramble", "casino", "tumor"};
// Getting a random word for the game
int num = ((int)Math.ceil(Math.random()*(WordList.length)));
String word = WordList[num];
// The puzzle to be displayed for the user to guess
int letters = word.length();
String hiddenWord = "";
for (int i=0; i<letters; i++){
hiddenWord+="-";
}
At the for loop, I get an error saying 'illegal start of type, cannot find symbol: class i'. 'i' is supposed to be an integer, which I've already declared, so I'm not sure why it's asking for a class.
There's also another error saying, 'identifier expected' and that there's a missing >. As my < is meant to be used as comparison (and not as a declaration or identifier), I don't understand this error.
For clarification, I should add that this is a desktop application in netbeans. The code is located after the line:
public class HangmanGameView extends FrameView {
Most of the rest of my code will be located within the actionPerformed code for my buttons. I need to be able to access the word and hiddenWord variables from within the code for the buttons, which is why I've put them here. I'm not positive if that's the problem as of yet. I'm also not sure where to put the code otherwise; there is no main method as far as I can see.
Edit: I hadn't posted the complete code because this is all I've done for now; the rest is all auto-generated by NetBeans, and I thought it wouldn't be relevant. But here it is:

You never initialise the Statement object....
Statement stmt = null; // Look ma, I'm null
// rs=(ResultSet) dlFollowUp.getFollowUpList();
// getFollowUplist();
ResultSet rs = null;
// Look ma, I'm still null
rs = stmt.executeQuery("SELECT id,customer,phone,product,lastsoldqty,consumption,lastsaledate,deliverydate,remark1,remark2,stock,invoiceno FROM followup");
You need to create the stmt before you can use...
stmt = connection.createStatement();
You may find reading through the JDBC tutorials of benifit
Problem #2
You define model as instance variable at the start of your FollowUp class...
private DefaultTableModel modelx, model;
But you never initialise it to anything....
I would imagine, based on your code, you would need to initialise it in your executeSearch method...
// You will need to fill this out with appropriate values,
// the number of columns in you JTable should match the
// the number columns from your query...
Object[] columns = new Object[]{....};
model = new DefaultTableModel(columns, 0);
while(rs.next()){
Object[] objects = new Object[colNo];
for(int i=0;i<colNo;i++){
objects[i]=rs.getObject(i+1);
}
model.addRow(objects);
}
