是的，您當然可以。這是一個例子：

這是java文件：

public class InvocationHelloWorld {

public static void main(String[] args) {

System.out.println("Hello, World!");

System.out.println("Arguments sent to this program:");

if (args.length == 0) {

System.out.println("(None)");

} else {

for (int i=0; i

System.out.print(args[i] + " ");

}

System.out.println();

}

}

}

還有一些使用它的C ++：

void invoke_class(JNIEnv* env) {

jclass helloWorldClass;

jmethodID mainMethod;

jobjectArray applicationArgs;

jstring applicationArg0;

helloWorldClass = (env)->FindClass("InvocationHelloWorld");

if(! helloWorldClass )

{

std::cerr<

return;

}

mainMethod = (env)->GetStaticMethodID(helloWorldClass, "main", "([Ljava/lang/String;)V");

if(! mainMethod )

{

std::cerr<

return;

}

applicationArgs = (env)->NewObjectArray(1, (env)->FindClass("java/lang/String"), NULL);

applicationArg0 = (env)->NewStringUTF("From-C-program");

(env)->SetObjectArrayElement(applicationArgs, 0, applicationArg0);

(env)->CallStaticVoidMethod(helloWorldClass, mainMethod, applicationArgs);

}
