`A Java programmer does not need to be aware of or understand Java bytecode at all. However, as suggestsd in the IBM developerWorksjoumat, ”Understanding bytecode and what bytecode is likely to be

`As each byte has 256 potential values, there are 256 possible opcodes. Of these. 0x00 through Dxca. Oxfe, and {buff are assigned values. Oxca is reserved as a breakpolnt tnstmcrion for Java debuggers and
`its type is not used by the language. Similarty. Dxfe and Dxff are not used by the language and are resewed for internal use by the Java Virtual machine.
