Methods and apparatus for creating compacted method signatures from method signature representations in Java õ class files are disclosed. The use of compacted signatures reduces the amount of memory space occupied by the signatures and, further, improves the efficiency with which a virtual machine may operate. According to one aspect of the present invention, a method for creating a compact representation of a method signature using a virtual machine includes creating 4-bit representations for each of the first parameter, a separator, and a return type included in the method signature. Once the 4-bit representations are created, the representations are packed into a word. In one embodiment, the word is a 32-bit word. In such an embodiment, the 32-bit word may be a 32-bit integer.
