Java 将 Unicode 字符串转换为英文字符串

Question

我是 java 的新手，我有这样的角色

"%6D%61%61%20%77%61%72%64%20%6C%6F%20%65%6E%6E%69%20%73%61%72%6C%75%20%68%6F%75%73%65%20%73%69%74%65%20%6B%6F%72%61%6B%75%20%61%70%70%6C%79%20%63%68%65%73%69%6E%61%20%6D%61%27%61%6D%20%65%74%75%76%61%6E%74%69%20%75%70%61%79%6F%67%61%6D%20%6C%65%6B%75%6E%64%61%20%69%6E%64%69%76%69%64%75%61%6C%20%70%6F%79%69%6E%64%69%20%74%72%79%20%63%68%65%79%61%6D%61%6E%74%61%72%61%61%20%76%61%64%69%6C%65%79%61%6D%61%6E%74%61%61%72%61%20%70%6C%65%61%73%65%20%73%65%6E%64%20%6D%65%20%61%6E%73%77%65%72"

当我尝试使用此 tool 转换它们时。我可以根据需要转换为值。

转换结果：

"maa ward lo enni sarlu house site koraku apply chesina ma'am etuvanti upayogam lekunda individual poyindi try cheyamantaraa vadileyamantaara please send me answer"

但是我如何以编程方式使用有人可以提供帮助吗？

我试过了

String raw = "%6D%61%61%20%77%61%72%64%20%6C%6F%20%65%6E%6E%69%20%73%61%72%6C%75%20%68%6F%75%73%65%20%73%69%74%65%20%6B%6F%72%61%6B%75%20%61%70%70%6C%79%20%63%68%65%73%69%6E%61%20%6D%61%27%61%6D%20%65%74%75%76%61%6E%74%69%20%75%70%61%79%6F%67%61%6D%20%6C%65%6B%75%6E%64%61%20%69%6E%64%69%76%69%64%75%61%6C%20%70%6F%79%69%6E%64%69%20%74%72%79%20%63%68%65%79%61%6D%61%6E%74%61%72%61%61%20%76%61%64%69%6C%65%79%61%6D%61%6E%74%61%61%72%61%20%70%6C%65%61%73%65%20%73%65%6E%64%20%6D%65%20%61%6E%73%77%65%72";
String searchSection = new String(raw.getBytes(StandardCharsets.UTF_8), "UTF-8");
System.out.println( searchSection);

如果这个问题与任何其他问题重复，请指出正确的方向谢谢

转换后的文本应该匹配

您可以使用 java.net 中的 URLDecoder.decode(yourMessage, "UTF-8") 实现它：

import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;

public class Main {
    public static void main(String[] args) {
        String yourMessage = "%6D%61%61%20%77%61%72%64%20%6C%6F%20%65%6E%6E%69%20%73%61%72%6C%75%20%68%6F%75%73%65%20%73%69%74%65%20%6B%6F%72%61%6B%75%20%61%70%70%6C%79%20%63%68%65%73%69%6E%61%20%6D%61%27%61%6D%20%65%74%75%76%61%6E%74%69%20%75%70%61%79%6F%67%61%6D%20%6C%65%6B%75%6E%64%61%20%69%6E%64%69%76%69%64%75%61%6C%20%70%6F%79%69%6E%64%69%20%74%72%79%20%63%68%65%79%61%6D%61%6E%74%61%72%61%61%20%76%61%64%69%6C%65%79%61%6D%61%6E%74%61%61%72%61%20%70%6C%65%61%73%65%20%73%65%6E%64%20%6D%65%20%61%6E%73%77%65%72";

        try {
            System.out.println( URLDecoder.decode(yourMessage, "UTF-8"));
        } catch (UnsupportedEncodingException uee) { }

    }
}

输出：
