Syntax error, insert "}" to complete ClassBody when making webView browser

Syntax error, insert "}" to complete ClassBody when making webView browser

When I do put a } to complete the class body then I get an unreachable
code error on the code above. I'm kinda new to android, thanks.
Here's the part of the code the error occurs under
class myWebClient extends WebViewClient
{
}
public void backButtonClicked(View view
The error is between the two { and }'s
