Answer:
FileOutputStream out = new FileOutputStream("ObjectData.dat");
ObjectOutputStream ostream = new ObjectOutputStream(out);
ostream.writeObject(r);
Explanation:
For object serialization, we can use the writeObject method of java.io.ObjectOutputStream class.
The complete code fragment is as follows:
import java.io.*;
class Demo{
public static void main(String args[]){
try{
r = <Reference to Object to be serialized> ;
FileOutputStream out = new FileOutputStream("ObjectData.dat");
ObjectOutputStream ostream = new ObjectOutputStream(out);
ostream.writeObject(r);
ostream.close();
} catch(Exception e){
e.printStackTrace();
}
}
}

Answer:
Python Code:
def validate_url(url):
#Creating the list of valid protocols and file name extensions
valid_protocols = ['http', 'https', 'ftp']
valid_fileinfo = ['.html', '.csv', '.docx']
#splitting the url into two parts
url_split = url.split('://')
isProtocolValid = False
isFileValid = False
#iterating over the valid protocols and file names for validity
for x in valid_protocols:
if x in url_split[0]:
isProtocolValid = True
break
for x in valid_fileinfo:
if x in url_split[1]:
isFileValid = True
break
#Returning the result if the URL has both valid protocol and file extension
return (isProtocolValid and isFileValid)
url = input("Enter an URL: ")
print(validate_url(url))
