I wanted to know if there is any standard APIs in Java to validate a given URL?

I want to check both if the URL string is right i.e.

Currently there are numerous solutions for validating URLs. the real issuse is that both methods dont check for "FILTER_FLAG_HOST_REQUIRED" which actually doesent work altough it should check ending... I have been trying to find a good solution for testing for URL's, I would not use the filter_var() for this kind of check. The only way i have found to check for them is either use regex or use the parse_url and check each section.

Validating URLs is important to form handling and PHP data processing.

sourceid=chrome-instant&ion=1&espv=2&es_th=1&ie=UTF-8#newwindow=1&q=check if valid url c# true: https://stackoverflow.com/questions/ask im using c#, how to enhance this checking url validation to be more accurate? Try Create', it doesn't helped me, because it return the result as true even though it obviously not a valid url.

Your Check URLValid is returning exactly what you have told it to. sourceid=chrome-instant&ion=1&espv=2&es_th=1&ie=UTF-8#newwindow=1&q=check if valid url c# This is an http S (Secure) url and your method says The main problem is that most strings are valid relative URL's so I would avoid using Uri Kind. Most web browsers silently add HTTP:// to the string to make it a valid url.

Assume that this regex will be used for a public URL shortener written in PHP, so URLs like shouldn’t pass (even though they’re technically valid).

Also, in this case I only want to allow the HTTP, HTTPS and FTP protocols. :ac|ad|aero|ae|af|ag|ai|al|am|an|ao|aq|arpa|ar|asia|as|at|au|aw|ax|az|ba|bb|bd|be|bf|bg|bh|biz|bi|bj|bm|bn|bo|br|bs|bt|bv|bw|by|bz|cat|ca|cc|cd|cf|cg|ch|ci|ck|cl|cm|cn|coop|com|co|cr|cu|cv|cx|cy|cz|de|dj|dk|dm|do|dz|ec|edu|ee|eg|er|es|et|eu|fi|fj|fk|fm|fo|fr|ga|gb|gd|ge|gf|gg|gh|gi|gl|gm|gn|gov|gp|gq|gr|gs|gt|gu|gw|gy|hk|hm|hn|hr|ht|hu|id|ie|il|im|info|int|in|io|iq|ir|is|it|je|jm|jobs|jo|jp|ke|kg|kh|ki|km|kn|kp|kr|kw|ky|kz|la|lb|lc|li|lk|lr|ls|lt|lu|lv|ly|ma|mc|md|me|mg|mh|mil|mk|ml|mm|mn|mobi|mo|mp|mq|mr|ms|mt|museum|mu|mv|mw|mx|my|mz|name|na|nc|net|ne|nf|ng|ni|nl|no|np|nr|nu|nz|om|org|pa|pe|pf|pg|ph|pk|pl|pm|pn|pro|pr|ps|pt|pw|py|qa|re|ro|rs|ru|rw|sa|sb|sc|sd|se|sg|sh|si|sj|sk|sl|sm|sn|so|sr|st|su|sv|sy|sz|tc|td|tel|tf|tg|th|tj|tk|tl|tm|tn|to|tp|travel|tr|tt|tv|tw|tz|ua|ug|uk|um|us|uy|uz|va|vc|ve|vg|vi|vn|vu|wf|ws|xn--0zwm56d|xn--11b5bs3a9aj6g|xn--80akhbyknj4f|xn--9t4b11yi5a|xn--deba0ad|xn--g6w251d|xn--hgbk6aj7f53bba|xn--hlcj6aya9esc7a|xn--jxalpdlp|xn--kgbechtv|xn--zckzah|ye|yt|yu|za|zm|zw)|(?
