Manipulasi Memori Java

Hello Guru Jawa! Secara umum, saya bertanya kepada diri sendiri soalan berikut: bolehkah saya membaca dan menulis ke dalam aplikasi proses yang saya tulis terima kasih kepada perpustakaan Manipulasi Memori Java ? Ini bukan kali pertama saya bertanya soalan ini, tetapi terdapat sedikit maklumat mengenai isu ini di Internet, kerana semua orang menulis bahawa ini adalah mustahil di Jawa, walaupun saya melihat beberapa catatan bahawa ini adalah nyata. Itulah sebabnya saya ingin meminta bantuan anda, bagaimana saya boleh melaksanakan produk ini? :)

    	//Get ProcessID
    	long pid = findProcessId("nuclearthrone.exe");
    	if(pid == 0) {
    		System.err.println("ProcessId not found.");
    		System.exit(1);
    	}
    	System.out.println(pid);

    	Pointer readProcess = openProcess(readRight, pid);//opens process with read privileges
    	Pointer writeProcess = openProcess(writeRight, pid);

    	int size = 4;//we want to read 4 bytes
    	int adress = Integer.parseInt("036CB314", 16);

    	//ReadMemory
    	 read = readMemory(readProcess, adress, size);
    	System.out.println(read.getInt(0));//value of memory read

    	//Write Memory
    	Cheater.writeMemory(4, 1079246848, writeProcess, adress);
