I have a String String a="123+>jo I want to en
code the String so that I can redirect it to an url. I initially tried it with urlencoder but in urldecoder +(plus) is removed while decoding.So i lost my data.
What is the right way to encode so that I get the same string while decoding also?

URLEncoder works perfectly. The plus sign is succesfully encoded into %2B.
Encoding: Works
Here is the IDEONE project: http://ideone.com/zMDur
import java.net.URLEncoder;
// ...
public static void main (String[] args) throws java.lang.Exception
{
String str = "123+>jo";
String str2 = "http://1.com/23+>jo";
System.out.println(URLEncoder.encode(str));
System.out.println(URLEncoder.encode(str2));
}
prints:
123%2B%3Ejo
http%3A%2F%2F1.com%2F23%2B%3Ejo
Encoding + Decoding: Works
The IDEONE project with decoding as well: http://ideone.com/Ypfv4
import java.net.URLEncoder;
import java.net.URLDecoder;
// ...
public static void main (String[] args) throws java.lang.Exception
{
String str = "123+>jo";
String str2 = "http://1.com/23+>jo";
System.out.println(URLDecoder.decode(URLEncoder.encode(str)));
System.out.println(URLDecoder.decode(URLEncoder.encode(str2)));
}
Prints:
123+>jo
http://1.com/23+>jo
So everything works using the java.net.URLEncoder and java.net.URLDecoder.
