在Java中使用空格对URL进行编码是不正确的

import java.net.URLEncoder;
import java.io.UnsupportedEncodingException;

public class URLEncodingExample {
    public static void main(String[] args) {
        String url = "https://www.example.com/search?q=java programming";
        try {
            String encodedUrl = URLEncoder.encode(url, "UTF-8");
            System.out.println("Encoded URL: " + encodedUrl);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }
}

Encoded URL: https%3A%2F%2Fwww.example.com%2Fsearch%3Fq%3Djava+programming
