String s =
URLDecoder.decode("http://www..../search_str=感冒","UTF-8");

It produces a String with 2 chinese characters after "search_str=",
namely "http://www..../search_str=\u611F\u5192" when written in Java's
\uxxxx syntax.

There's a String constructor that takes an array of bytes and the name
of the character set.
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html#String(byte[], java.lang.String)

So it'd be...
String s = new String(myByteArray, "UTF8");

JavaDoc is your friend. If you want to make an instance of class X, the
first place to look is the list of constructors and static (factory)
methods in the javadocs for class X. Not always the right answer for a
question like that, but it's the place to start...

That looks like some flavour of armoured utf-8. See

It is probably URL-encoded.

Shove it in a java.net.URI, and extract the parts you want. This should
ensure that extraction occurs before decoding, since you don't want to
misinterpret an encoded character as a separator.

For me, this program appears to do the job:

import java.net.*;

public class Decode {
public static void main(String[] args) throws Exception {
for (String a : args) {
URI u = URI.create(a);
System.out.println("Arg: " + a);
System.out.println("URI: " + u);
System.out.println("Scheme: " + u.getScheme());
System.out.println("Authority: " + u.getAuthority());
System.out.println("UserInfo: " + u.getUserInfo());
System.out.println("Host: " + u.getHost());
System.out.println("Port: " + u.getPort());
System.out.println("Path: " + u.getPath());
System.out.println("Query: " + u.getQuery());
System.out.println("Fragment: " + u.getFragment());
}
}
}
