Different types of bytecode use differentsyntax, which can be read and executed by the corresponding virtual machine. A popular example is Java bytecode, which is compiled fromJavasource code and can be run on a Java Virtual Machine (JVM). Below are examples of Java bytecode instructions. ...
It’s verbose.You have to define a separate class with all of the associated ceremonial verbiage for each data type. Note that in the previous examples, we showed the entire definition ofallof the value types. Here, we only cover one!
With invokevirtual and invokeinterface the difference is not that obvious however. Let me offer a very simplistic explanation of the difference for these two instructions. Imagine that the class definition contains a table of method definitions and all the methods are numbered by position. Here's an...

It may be useful to think of this as the instruction successfully executing (in a sense), and the exception getting thrown after the instruction but before the next one gets a chance to run. This definition makes it possible for a method to use a monitor cleanup catch-all (e.g., ...
