When Craig said There's a specification that must be followed by all environments that want to provide an implementation of a JVM. What does he mean by environment ?

14,661 PointsWhat he means by this is that for something to call itself a java virtual machine, it must follow these specifications: https://docs.oracle.com/javase/specs/jvms/se7/html/ Otherwise it will not be able to run java code as expected. PS: This is VERY technical, and you need not worry about it, unless you want to implement a JVM.
The reason this is mentioned is probably because there are a lot of different JVM's to choose from, even though Sun's is the most common one, but since they all follow the same specifications, you can in theory choose any JVM you'd like. (In theory)
