3. The computer-implemented method of claim 1 , wherein the generating comprises associating the generated interpreter loop with the called method.

generating the interpreter loop for the called method based on the generated operation code set.

6. The method of claim 1 , wherein if the called method is not a bottleneck method, associating the called method with the primary interpreter loop without generating the interpreter loop for the called method and interpreting the bytecode of the called method using the primary interpreter loop.

7. The method of claim 6 , wherein if an interpreter loop was previously generated for the bottleneck method, associating the previously generated interpreter loop for the called method without generating the interpreter loop.

8. A computer-implemented method of interpreting a method bytecode, comprising:

determining whether a called method is a bottleneck method;

providing an associated interpreter loop for the called method if the called method is determined to be the bottleneck method; and

interpreting a bytecode of the called method using the provided interpreter loop;

wherein no interpreter loop is generated until after a virtual machine comprising a primary interpreter loop is built, wherein the determining whether a called method is a bottleneck method is determined by the primary interpreter loop.

9. The computer-implemented method of claim 8 , wherein the determining comprises determining the called method based on a number of times the called method is called.

10. A system implemented by a computer for interpreting a method bytecode, the system comprising:

a processor for interpreting the method bytecode;

an operating system;

an application; and

a virtual machine, which is based on the operating system, provides an interface for the application, and interprets a bytecode of a method called from the application to convert the interpreted bytecode into a code recognizable by the operating system, the virtual machine comprising a primary interpreter loop;

wherein the virtual machine interprets the bytecode of the called method using an interpreter loop associated with the called method if the called method is a bottleneck method;

wherein no interpreter loop is generated until after the virtual machine is built, wherein the determining whether a called method is a bottleneck method is determined by the primary interpreter loop.

11. The system of claim 10 , wherein whether the called method is the bottleneck method is determined based on a number of times the called method is called.

12. The system of claim 10 , wherein the virtual machine is used by generating the interpreter loop for the called method.

13. The system of claim 10 , wherein the virtual machine generates a predetermined operation code handler for the called method, and updates a previously generated interpreter loop using the generated operation code handler to generate the interpreter loop for the called method.

14. The system of claim 10 , wherein the virtual machine generates an operation code set of the called method if the called method is the bottleneck method, and generates the interpreter loop for the called method based on the generated operation code set.

15. A computer-readable medium storing instructions for interpreting a method bytecode, the instructions comprising:

determining whether a called method is a bottleneck method;

generating an interpreter loop for the called method if the called method is the bottleneck method; and

interpreting a bytecode of the called method using the generated interpreter loop;
