TextField and Password field not being detected

Question

Need to help knowing the reason why the textfield and password field is not being detected? So this is where I see the error (the red lines on txtUsername and PW)

private void btnLoginActionPerformed(java.awt.event.ActionEvent evt) {                                         
    if(txtUsername.getText().length()==0) {
        JOptionPane.showMessageDialog(null, "Please fill up blank field/s!");
    }
    else if(PW.getPassword().length==0) {
        JOptionPane.showMessageDialog(null, "Please fill up blank field/s!");
    }
    else {
        String user = txtUsername.getText();
        char[] pass = PW.getPassword();
        String pwd = String.copyValueOf(pass);
        if(validate_login(user,pwd))
            JOptionPane.showMessageDialog(null, "Correct Login Credentials!");
        else 
            JOptionPane.showMessageDialog(null,"Incorrect Login Credentials!");
    }
}

Before i put this code:

private boolean validate_login (String username, String password) {
    try {
            Class.forName(".com.mysql.jdbc.Driver");
            Connection con= DriverManager.getConnection("jdbc:mysql://localhost:3306/logins" + "user=root&password=");
            PreparedStatement pst = con.prepareStatement("Select * from admin where username=? and password=?");
            pst.setString(1, username);
            pst.setString(2, password);
            ResultSet rs = pst.executeQuery();
            if(rs.next()) {
                return true;
            }
            else
                return false;
    }
      catch(SQLException e) {
        e.printStackTrace();
        return false;
    }    

    }
}

It doesnt have any error. Now its giving me lots of errors since i've put that code but that method alone doesnt have errors in it. Can you please help me? Thank you.

In your validate_login method, there is unnecessary curly brace. Remove the bottom brace
