Given a URL as string, we need to find if the given URL is valid or not.
Input : str = "https://www.geeksforgeeks.org/" Output : Yes Input : str = "https:// www.geeksforgeeks.org/" Output : No Note that there is a space after https://
Using java.net.url
We can use java.net.url class to validate a URL. The idea is to create a URL object from the specified String representation. If we do not get exception while creating the object, we return true. Else we return false.
// Java program to check if a URL is valid // using java.net.url import java.net.URL;
class Test {
/* Returns true if url is valid */
public static boolean isValid(String url)
{
/* Try creating a valid URL */
try {
new URL(url).toURI();
return true ;
}
// If there was an Exception
// while creating URL object
catch (Exception e) {
return false ;
}
}
/*driver function*/ public static void main(String[] args)
{
if (isValid(url1))
System.out.println( "Yes" );
else
System.out.println( "No" );
if (isValid(url2))
System.out.println( "Yes" );
else
System.out.println( "No" );
}
} |
Output:
Yes No
