SYSTEM FOR REDUCING COMPILE TIME OF BYTE CODE IN JAVA PROGRAM AND METHOD BY GENERATING NATIVE CODE

摘要

PURPOSE: A system for reducing a compile time of a byte code in a Java program is provided to compile a frequently used byte code as a native code to store the native code while executing a Java program, and to read the native code for the byte code while executing the Java program later, thereby reducing time for generating the native code by compiling the byte code. CONSTITUTION: A class loader(100) loads a byte code generated by compiling a Java program source code. The first memory(200) maintains the loaded byte code and a native code generated by compiling the byte code in accessible state. The second memory(400) stores the native code loaded in the accessible state. A native code manager(300) retrieves the native code stored in the second memory(400) at the request of the class loader(100), and loads the native code into the first memory(200). An execution portion(500) executes the loaded native code.
