Manipulation de la mémoire Java

Bonjour gourou Java ! De manière générale, je me suis posé la question suivante : puis-je lire et écrire dans les processus des applications que j'ai écrites grâce à la bibliothèque Java Memory Manipulation ? Ce n'est pas la première fois que je pose cette question, mais il y a très peu d'informations sur ce problème sur Internet, car tout le monde écrit que c'est impossible en Java, même si j'ai vu certains articles disant que c'est réel. C'est pourquoi je voulais vous demander de l'aide, comment puis-je mettre en œuvre ce produit ? :)

public static void main(String args[]) {
    	//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);
    }

    static long findProcessId(String processName) {
