What is URL Encoding?

URL Encoding is the process of converting data into CGI form so that it can travel across the network without any issues. URL Encoding strip the white spaces and replace special characters with escape characters. We can use java.net.URLEncoder.encode(String str, String unicode) to encode a String. URL Decoding is the reverse process of encoding and we can use java.net.URLDecoder.decode(String str, String unicode) to decode the encoded string. For example “Pankaj’s Data” is encoded to “Pankaj%27s+Data”.
