Answer from cs61c-ao (Roger Tseng 16507336) for Question 3
the java equivalent to malloc in C is the 'new' keyword.    this basically allocates a new free block in memory for a  certain object that is being declared.  java doesn't have an equivalent to free because it uses automatic garbage collection so there is no way to manually deallocate in java.  

the C language has many kinds of dynamically allocated objects unlike Lisp.  though it does store type information with every object a standard location, but it  is not strongly typed.
