If you want find or check you have to connected to internet or not. It is simple to code of your application like this:

First you have to create custom class, ConnectionDetector.java

public class ConnectionDetector {
         private Context _context;
             public ConnectionDetector(Context context){
            this._context = context;
        }
        public boolean isOnline(){
            ConnectivityManager cm = (ConnectivityManager)  _context.getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo ni = cm.getActiveNetworkInfo();
            if (ni != null && ni.isConnected())
            {
                return true;
            }
            return false;
        }
}

Now call to the mainactivity java class,

ConnectionDetector cd = new ConnectionDetector(getApplicationContext());
        
      Boolean  isInternetPresent = cd.isOnline();
        if (isInternetPresent) {

  //Do Something if internet connection 

  }
