How to check image exist in a particular location?

Question

Is there any way to check image exist in a particular location except the following code?This code is taking too much time.

  static boolean isImage(String image_path){  
    InputStream input = null;
    try{

        URL url = new URL(image_path);
        input = url.openStream();
        return  true;

    }catch(Exception ex){
        return  false;
    }

  }

I don't have permission and exist() method returns true if file exist and have permission @ Jonjongot? — amitguptageek, Feb 06 '15 at 07:24
if you don't have permission on it, it will throw `SecurityException`. means if you get this exception, the file is exist. — Baby, Feb 06 '15 at 07:34
@ Jonjongot I am getting false even if file exists not SecurityException. — amitguptageek, Feb 06 '15 at 07:53
not sure if you get what i'm saying or I don't understand you. Try add one more catch block just before your catch block above `catch(SecurityException se){ return true; }` — Baby, Feb 06 '15 at 07:57

If you just want to check if the file exists:

static boolean isImage(String image_path){  
    try{
        File f = new File(image_path);
        return  f.exists();

    }catch(Exception ex){
        return  false;
    }
}
