References in Java

• Student presentations of independently researched Java topic.
• Dynamic memory allocation in Java:
  • What new does
  • Allocation in the heap
  • Garbage collection
  • Issues in other languages and discussion of why these problems do not appear in Java (or do they?):
    • deallocation of memory and deconstructors (in C/C++)
    • dangling pointers
    • memory leaks
• Static variables and methods
• Summary of memory allocation for variables:
  • Function parameters and local variables: on the stack. Basic types and references only.
  • Object variables allocated with new: on the heap. All class variables (except static) are part of the space allocated for each object.
  • Static variables in classes: allocated statically (not at run time), only once.
• Summary of memory allocation types: static (determined at compilation time) and dynamic (determined at run time).
