Else statement not recognised java

 private void EnterbuttonActionPerformed(java.awt.event.ActionEvent evt) {                                            

    if (Usernamefield.getText().equalsIgnoreCase("User"));
    if (Passwordfield.getText().equalsIgnoreCase("420"));
{
    JOptionPane.showMessageDialog(null, "Welcome, User!");   
}                                           
else 
{

    JOptionPane.showMessageDialog(null, "Wrong Username/Password!");

}

It says that an else statement cannot work without an if, there are clearly 2 if statements however. I would like to create a simple log-in GUI in Java.
