Java语言怎么在程序运行之后对程序运行的代码进行动态编辑，让程序按照编辑以后的代码进行执行的操作是什么方法

import javax.tools.JavaCompiler;
import javax.tools.ToolProvider;
import java.io.*;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

public class DynamicCodeExecution {

    public static void main(String[] args) {
        // 原始代码
        String code = "public class HelloWorld {\n" +
                "    public static void main(String[] args) {\n" +
                "        System.out.println(\"Hello, World!\");\n" +
                "    }\n" +
                "}";

        // 将原始代码写入到文件中
        String fileName = "HelloWorld.java";
        try (BufferedWriter writer = new BufferedWriter(new FileWriter(fileName))) {
            writer.write(code);
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 动态编译代码
        JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
        int result = compiler.run(null, null, null, fileName);
        if (result != 0) {
            System.err.println("编译失败");
            return;
        }

        // 动态加载类
        ClassLoader classLoader = DynamicCodeExecution.class.getClassLoader();
        try {
            Class<?> helloWorldClass = classLoader.loadClass("HelloWorld");

            // 执行代码
            Method mainMethod = helloWorldClass.getDeclaredMethod("main", String[].class);
            mainMethod.invoke(null, new Object[] {null});
        } catch (ClassNotFoundException | NoSuchMethodException | IllegalAccessException | InvocationTargetException e) {
            e.printStackTrace();
        }
    }
}
