[SOLVED] [newbie] chart[].equals(char[]) ??

[jon80]

'm trying to check a password, however, I'm stuck trying to validate the JPasswordField.getPassword():

    
 private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
        char[] expectedPwd = {'p','a','s','s','w','o','r','d'};

        if (!(userName.getText().equals("joe") &&
                (pwd.getPassword()==(expectedPwd))))
        {
            jLabel3.setText("Logon failed!");

            /* FIX
             reset values to be on the safe side
            expectedPwd = null;
            pwd.setText("");
            */

            if (debug)
            {
               // System.out.println("userName= " + userName.getText());
                System.out.print("password=");
                System.out.println(pwd.getPassword());

                System.out.print("expectedPwd=");
                for (int i = 0; i < expectedPwd.length; i++)
                {
                     System.out.print(expectedPwd[i]);
                }
            }
        }
    }

    ...

   [b]//this doesn't work![/b] 
    private boolean isEqual (char[] array1, char[] array2)
    {
        int countMatching = 0;
            for (int i = 0; i < array1.length; i++)
            {
                if (array1.[i] == array2[i]) //FIX
                    countMatching++;
            }
    
    }

:confused:

you should post what you mean by "doesn't work", if it gives an actual error, if it's behaving a certain way and not how you expect it to, etc. i highly doubt this will even compile.

It means 'I don't really know why'.

The output from debug statements I've written:

 if (debug)
            {
               // System.out.println("userName= " + userName.getText());
                System.out.print("password=");
                System.out.println(pwd.getPassword());

                System.out.print("expectedPwd=");
                for (int i = 0; i < expectedPwd.length; i++)
                {
                     System.out.print(expectedPwd[i]);
                }
            }
        }

Output:
password=password
expectedPwd=passwordBUILD SUCCESSFUL (total time: 8 minutes 24 seconds)

That was quite a bit! :)

It does compile, however, I've removed the part where I'm saying //doesn't work. So,

1. Should I override the char[].equals() method, or is it overly complicated? How do I do it?
2. How would you write a method that compares char[] values for equality?
3. Anything else?

public class Test {
    public static void main(String[] args) {
        String password = "password";
        String testStr = "password";
        System.out.println(" equals: " + password.equals(testStr));
        System.out.println("isEqual: " + test(password, testStr));
    }

    private static boolean test(String s1, String s2) {
        return isEqual(s1.toCharArray(), s2.toCharArray());
    }

    private static boolean isEqual(char[] c1, char[] c2) {
        if(c1.length != c2.length) {
            return false;
        }
        for(int i = 0; i < c1.length; i++) {
            if(c1[i] != c2[i]) {
                return false;
            }
        }
        return true;
    }
}
