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.
Re: Getting Password from Password Field
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.

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.

Post runnable code that demonstrates the error.
Re: Getting Password from Password Field
you forgot the .getText() in the password Field
now it should work perfectly .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!"); } }
