How to Validate a URL Using Java

Greetings, I am back with another tutorial and today I am here with how validate a URL(Uniform Resource Locator). We can do this by attempting to create a URL object and parsing in string input containing the URL we wish to validate. A try catch statment can be used, if an error occurs, return a false, if no error occurs, return a true. Thanks for watching and have a spectacular day.

}
catch (Exception e)

System.out.println(e);
return false;
