Helo about using passwordfield with database

Question

im new to passwordfield stuff because i use textfield and i can use it very well
my error is
setString(int,java.lang.String) in java.sql.PreparedStatement cannot be applied to (int,char[])
and the second error
symbol : method equals(char[],java.lang.String)
location: class java.util.Arrays
if(uname.equals(result.getString(1)) && Arrays.equals(pass,result.getString(2)))
here is my code
String uname = txtusername.getText();
      char pass[] = txtpassword.getPassword(); // <--- see i use passwordfield and it has a method getpassword()
     if(uname.length() < 1 || pass.length < 1)
     JOptionPane.showMessageDialog(null, "Please enter your username and password");
     else
        try
            Class.forName(driver);
        }//end try
        catch(Exception e)
           JOptionPane.showMessageDialog(null, "Failed to load MySql driver!");
           return;
        }//end catch
        try
            con = mydb.getmyconnection();
            String statement = "Select * from login where username = ? and password = ?";
            PreparedStatement preparedst = mydb.getmyconnection().prepareStatement(statement);
            preparedst.setString(1, txtusername.getText());
            preparedst.setString(2, txtpassword.getPassword()); // <---here i have an error too if i use getpassword but if i use gettext its fine
            ResultSet result = preparedst.executeQuery();
            while(result.next())
             if(uname.equals(result.getString(1)) && Arrays.equals(pass,result.getString(2)))
                JOptionPane.showMessageDialog(null, "Login Successful!");
                inserttable.main(null);
                this.dispose();
              else
                  JOptionPane.showMessageDialog(null, "invalid login");
            preparedst.close();
            con.close();
           catch(SQLException e)
            JOptionPane.showMessageDialog(null, e.getMessage());
     }//end else
}                 but if i use gettext instead of getpassword and i change my code with this it works fine
String uname = txtusername.getText();
      String pass = txtpassword.getText();
     if(txtusername.getText().length() < 1 || txtpassword.getText().length() < 1)
     JOptionPane.showMessageDialog(null, "Please enter your username and password");
     else
        try
            Class.forName(driver);
        }//end try
        catch(Exception e)
           JOptionPane.showMessageDialog(null, "Failed to load MySql driver!");
           return;
        }//end catch
        try
            con = mydb.getmyconnection();
            String statement = "Select * from login where username = ? and password = ?";
            PreparedStatement preparedst = mydb.getmyconnection().prepareStatement(statement);
            preparedst.setString(1, txtusername.getText());
            preparedst.setString(2, txtpassword.getText());
            ResultSet result = preparedst.executeQuery();
            while(result.next())
              if(uname.equals(result.getString(1)) && pass.equals(result.getString(2)))
                JOptionPane.showMessageDialog(null, "Login Successful!");
                inserttable.main(null);
                this.dispose();
              else
                  JOptionPane.showMessageDialog(null, "invalid login");
            preparedst.close();
            con.close();
           catch(SQLException e)
            JOptionPane.showMessageDialog(null, e.getMessage());
     }//end else

Answer 1

i did that already with .equals method but its not working if i use passwordfield if i enter invalid username and password nothing happened
            while(result.next())
              if(uname.equals(result.getString(1)) && pass.equals(result.getString(2)))
                JOptionPane.showMessageDialog(null, "Login Successful!");
                inserttable.main(null);
                this.dispose();
              else
                  JOptionPane.showMessageDialog(null, "invalid login");
              }nvm i change the code and got the idea of you thank's
