Value types

A variable of value type contains its value

The values are allocated on the method stack or within objects on the heap

Variables of value types are dealt with by use of so-called value semantics

Use of value types simplifies the management of short-lived data

Value semantics
- Assignment, call-by-value parameter passing, and return copy entire values
The method stack
- The memory area where short-lived data is allocated
  - Parameters and local variables
- Allocation takes place when an operation, such as a method, is called
- Deallocation takes place when the operation returns
