The Java virtual machine provides some support for dynamically typed languages. Most of the extant JVM instruction set is statically typed - in the sense that method calls have their signatures type-checked at compile time, without a mechanism to defer this decision to run time, or to choose the method dispatch by an alternative approach. JSR 292 (Supporting Dynamically Typed Languages on the Java Platform) added a new invoke… WebBytecode is a simplified binary language similarly to machine code.
