I have a code below, this will be triggered when i press a button

Java Code:
final EditText et = (EditText) findViewById(R.id.editText1);
final Button b = (Button) findViewById(R.id.button1);
final TextView tv = (TextView) findViewById(R.id.textView1);

URL url = null;
url = new URL("http://www.google.com");
URLConnection conn = url.openConnection();
    					
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line = "";
while ((line = reader.readLine()) != null) {
   tv.append(line);
}
I got this from a tutorial video and i was trying it out but i couldn't make it work
It will get the html code of a website then it will be copied into textview

Below is the error I get when I press the button

I'm new to java so I don't know what to do.
