如何查看特定位置的图像？

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;
    }

  }

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;
    }
}
