I want to present the username from database JAVA Jframe

I have two JFrame windows one for the login and the second for the welcome. Now I want to present the Firstname and the Lastname of the connected user near to the hello in the welcome screen.
I tried many things but none of them worked so I'm asking for you help. I just started to learn GUI:

In your code, you does not seem to load the username or password of the logged in user at the welcome frame. Either you will have to pass that from the login frame or you will have to re-query the database and get firstname and lastname.
I suggest, simply pass the firstname and lastname from welcome screen via constructor.
In successful login, simply pass the name in the constructor: Login code addition:
} else if(c == 1) {
JOptionPane.showMessageDialog(null, "Hello to you, " + Firstname +" "+ Lastname);
frame.dispose();
UserPage UserFrame = new UserPage( Firstname, Lastname );
UserFrame.setVisible(true);
}
In the welcome frame, add a constructor to handle this:
public UserPage(String loggedInFirstName, String loggedInLastName){
// your remaining code
JLabel lblNewLabel = new JLabel("Hello, " + loggedInFirstName + " " + loggedInLastName );
// your remaining code.
}
A approach like this might work for your case and don't forget to mark the answer as accepted if this works for you

populate JTable with the value selected in Jcombobox

I have a JCombobox and JTable
and database
jcombobox is filled with the value of first_name of student table from databse.
Whenever I select a name from database I want the value of Course name from course and student_score from score table of the database to be displayed in Jtable.
Basically I want to display the records of selected in JComboBox in Jtable

} catch (Exception e1) {
e1.printStackTrace();
}
}
}

String n=(String)comboBox.getSelectedItem();
String sql="SELECT .... WHERE student.first_name=n)";
That code doesn't do anything with the variable "n". You can't just include "n" as part of the String because all the have is the character "n", not the value of the variable.
You were given a link to a tutorial on using a PreparedStatement in your last question (Populate JTable with the value in JCombobox).
So where do you use the "?" which indicates you want to provide a dynamic value to the SQL statement?
Your basic code should be:
String sql="SELECT ..... where student.first_name = ?)";
PreparedStatement ps = con.prepareStatement(sql);
ps.setString(1, n);
ResultSet rs = ps.executeQuery();
Now the value of the variable "n" will replace the "?" in the SQL string.
Assuming the rest of your SQL is correct then it should work.

How do I input data from java GUI into MS Access using UCanAccess

public void actionPerformed(ActionEvent e) {
}
}
I need to get the code to send data when the submit button is clicked. This is a school project where I have to allow users to enter water usage and bill (water utility bill), so I can display it later.
I have ran the code previously and but errors like "unexpected token" or "user has no privilege or object not found".

There are some notes :
You get this error (unexpected token) because the names of columns and table should not be between two quotes ''
The + operator is not allow in that position of query
Also, only the Strings can be between two quotes not the ints, make sure the type of ID for example is a String, if not you have to remove the two quotes
Read about Prepared Statement to avoid syntax error and to prevent SQL Injection
Look at :
String sql="insert into db ('ID', 'WaterUsage', 'Bill') + values ('1', '12', '12')";
//(1)-----------------------^--^--^----------^--^----^ ^ ^ ^
//(2)___________________________________________________| | |
//(3)_____________________________________________________________| |

That helped me a lot and with the help of my friends i completed my code, for anyone who might need this at any point, i'll be including my code.

SQL Syntax Error In Java and MySql SELECT Query

I've searched the stackoverflow forum and carried out the possible solution given here
Can anyone please guide me how to handle this error?
Thanks In Advance :)

All of the above code is basically useless. It's an SQL syntax error, which means it's this one line:
... WHERE userame='"+_username+"', password='"+_password+"' ";
^---
you don't use , to separate where clause arguments. You use boolean operations. and, or, etc...
And note that you're vulnerable to sql injection attacks

You were using a comma , between your WHERE clauses rather than an AND.
String sql = "SELECT userame, password FROM registration WHERE userame='"+_username+"' AND password='"+_password+"' ";

How can I make my table update?

I use SQLite. I have 2 JFrames. 1st is consists of table and "Load data", "Edit data". Click on Edit make the new, 2nd JFrame to appear. I want my table to be updated after I make some changes with a help of class Edit. How do I make it? One idea is to use ActionListener so that after I click save, delete or update buttons in JFrame2 method of Jframe 1, which stays for updating of the table(using query), is called. I have tried, but it does not work. I do not want the method of the 1 Jframe to be called in 2nd Jframe, I want this method to be called in 1st Jframe. What are possible solutions?
