Explain URL Encoding?

URL Encoding means the changing of data into CGI. It is done to circumvent any type of issue while it is going over the network. URL coding is schemed by removing the white spaces and put any escape symbols. Thus, the special characters are removed. To encode any string java.net.URLEncoder.encode (String str, String Unicode) is used and to decode the URL java.net.URLDecoder.decode (String str, String Unicode) is used. Let's take an example to simplify it. To encode 'Ravi's data' it is changed into 'Ravi/24d+data'.
