Does Android Runtime(ART or Dalvik) contain Java VM stack or Native Method Stack like JVM?

Question

According to Oracle Docs Run-Time Data Areas states, JVM contains various parts of data areas: And I also learnt that JVM is stack-based and ART/Dalvik is register-based. Dalvik heap is made of Active Heap and Zygote Heap.
Questions are as following:
1. What is the difference between "Stack" in stack-based and "Stack" in Java VM stack/Native Method Stack.
2. Does ART/Dalvik contain stacks like Java VM stacks in JVM?
3. What do ART/Dalvik Run-Time Data Areas look like?

Answer 1

1. What is the difference between "Stack" in stack-based and "Stack" in Java VM stack/Native Method Stack.

They refer to the same thing. A "stack based" VM uses the stack of its memory space in order to carry out logical and arithmetic operations.

Does ART/Dalvik contain stacks like Java VM stacks in JVM?

The Android VM implementation (both Dalvik and ART) are not Stack based , but instead Register based . One thing this allows Android to do is directly map virtual registers to real hardware registers, which improves execution speed and efficiency.

3. What do ART/Dalvik Run-Time Data Areas look like?

You can see an example of this, and read more about stack-based vs register-based VMs here .
