URL就是搜索欄中似亂碼的字符串妒茬，就是所謂的application/x-www-form-urlencoded MIME字符串
編程中涉及普通字符與這些字符的轉(zhuǎn)換妻率，就需要使用URLDcoder和URLEncoder
import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;
import java.net.URLEncoder;
public class URL {
public void main(String[] args) throws UnsupportedEncodingException{
String s=URLEncoder.encode("www.baidu.com","GBK");
System.out.println(s);
String s1=URLDecoder.decode("http://www.reibang.com/writer#/notebooks/9036412/notes/13324610","GBK");
System.out.println(s1);
}
}
