authentification error

[mharsijamel]

i have two classes:
-autentifier
-shrimp

shrimp was the first one, i added "authentifier" to add authentification
i wrote this method:

int i;
        for (i = 0; i < logins.length; i++)
        {
            
            if (text_login.getText().equalsIgnoreCase(logins[i]))
            {
                
                if (!text_password.getText().equalsIgnoreCase(passwd[i]))
                {
                    System.out.println(text_password.getText());
                    System.out.println(passwd[i]);
                    JOptionPane.showMessageDialog(null, "Invalid password", "Dialog Message", JOptionPane.ERROR_MESSAGE);
                    text_password.setText("");
                    break;

                }
                else
                {
                    System.out.println("3");
                    new Shrimp();
                    
                    this.setVisible(true);
                    break;
                }
            }

        }
        if (i == logins.length)
        {
            JOptionPane.showMessageDialog(null, "Invalid login", "Dialog Message", JOptionPane.ERROR_MESSAGE);
            text_login.setText("");

        }

if authentification was good, my java program shows "build successful" and stop run, or it crashes

You do not think it would be wise to give out an error description or code that compiles, right?

[mharsijamel]

there is no error
it just shows, after authentification success, build successfull, and it don't run "shrimp"
if i made "shrimp" like start class, it run without problem

[Sierra]

Sorry, your information is not sufficient to tell you what is wrong. How should we tell you what is wrong with your starting class if we do not even know what it looks like?
MAybe someone else could read the crystal ball for you.

[mharsijamel]

this is the shrimp class; shis class if it is the run class, it run without problem
