control system of the memory using a JAVA and controlling method therefore

PURPOSE: A device for controlling a memory using the Java and a controlling method thereof are provided to prevent the memory from over-storing by freely storing/removing data of a Java heap memory when a Java program is developed. CONSTITUTION: A memory model block(1) checks an amount of a dynamic Java heap memory by storing/removing the Java data. A memory controller(2) outputs a storing/removing signal of a data object after checking the memory amount of the memory model block, and informs the program of a storing state for the memory model block. A control block(4) controls a preference function and a function of the memory, and processes development signals and control instructions inputted from a user instruction part(3) when the Java program is developed. A thread model block(5) previously generates/stores various forms of threads generated when the Java program is operated, and manages the thread information. A thread controller(6) generates the thread information of the thread model block or makes the thread model block cancel/block the useless threads.
