文字列変数に格納された Java コードを実行するにはどうすればよいですか?

<code class="java">// Create a Java source code string
String javaCode = "...";

// Create a Java compiler instance
JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();

// Create a source code file from the string
JavaFileObject javaFile = new StringJavaFileObject("MyCode", javaCode);

// Compile the source code
DiagnosticCollector<JavaFileObject> diagnostics = new DiagnosticCollector<>();
Iterable<? extends JavaFileObject> compilationUnits = Collections.singletonList(javaFile);
compiler.getTask(null, null, diagnostics, null, null, compilationUnits).call();

// Execute the compiled code
Class<?> clazz = Class.forName("MyCode");
Method method = clazz.getDeclaredMethod("myMethod");
method.invoke(null);</code>

<code class="java">// Create a Beanshell interpreter and add the Java code to it
Interpreter interpreter = new Interpreter();
interpreter.eval(javaCode);

// Access the defined classes and methods in the interpreter
Class<?> myClass = interpreter.getClassLoader().loadClass("MyClass");
Method method = myClass.getDeclaredMethod("myMethod");
method.invoke(null);</code>
