Check password fields with each other

How do I validate two password fields if both are the same? 

if(pfSenha.getPassword() == pfCSenha.getPassword()) {
    JOptionPane.showMessageDialog(null, "Senhas conferem!");
} else {
    JOptionPane.showMessageDialog(null, "Senhas não conferem!");
}

I've tried ... 

if(new String(pfSenha.getPassword()) == new String(pfCSenha.getPassword())) {
    JOptionPane.showMessageDialog(null, "Senhas conferem!");
} else {
    JOptionPane.showMessageDialog(null, "Senhas não conferem!");
}

How can I resolve?

The problem with your code is the == operator.

In Java == compares if two objects point to the same reference (only for non-primitive types, of course). In your case, you should use the method .equals() 

if(new String(pfSenha.getPassword()).equals(new String(pfCSenha.getPassword()))) {
    JOptionPane.showMessageDialog(null, "Senhas conferem!");
} else {
    JOptionPane.showMessageDialog(null, "Senhas não conferem!");
}
