    Exclamation Getting Password from Password Field

    Hi, Bradley here.

    I am new to JAVA GUI programming and was wondering how you go about getting and testing if a password field text equals something. For example, if the password equals "password" then do something.

    Any help would be greatly appreciated.

    Cheers, Bradley.

    With GUI you can use equalsIgnoreCase() or you can use the standard equals() method.
    Remember the equality operator '==' does not work on String in Java.

    Angry Re: Getting Password from Password Field

    Hi.

    I have tried the equals() method, but I get a warning saying: ".equals() on incompatible types, flips operands of the binary operator invert if."

    Here is my code:
        private void loginButtonActionPerformed(java.awt.event.ActionEvent evt) {                                            
            if(usernameText.getText().equals("username") && passwordText.equals("password"))
            {
                loginSuccessfulLabel.setText("Login Successful!");
            }
            else
            {
                loginSuccessfulLabel.setText("Login Failed!");
            }
        }

    Is there something I am doing wrong?

    Cheers, Bradley.

    you forgot the .getText() in the password Field
        private void loginButtonActionPerformed(java.awt.event.ActionEvent evt) {                                            
            if(usernameText.getText().equals("username") && passwordText.getText().equals("password"))
            {
                loginSuccessfulLabel.setText("Login Successful!");
            }
            else
            {
                loginSuccessfulLabel.setText("Login Failed!");
            }
        }
    now it should work perfectly .
