Hello Java Guru! Sa pangkalahatan, tinanong ko sa aking sarili ang sumusunod na tanong: maaari ba akong magbasa at sumulat sa mga proseso ng aplikasyon na isinulat ko salamat sa Java Memory Manipulation library ? Hindi ito ang unang pagkakataon na tinanong ko ang tanong na ito, ngunit napakakaunting impormasyon sa ang isyung ito sa Internet, dahil isinulat ng lahat na imposible ito sa Java, kahit na nakita ko ang ilang mga post na ito ay totoo. Kaya nga gusto kong humingi ng tulong sa iyo, paano ko maipapatupad ang produktong ito? :)
