Make 2 classes WrapperShallow and WrapperDeep. Each class is simply a wrapper class to hold a private array variable. int [] a; The default constructor for each class should initialize â??aâ??. Each class should have a toString() and equals(). Each class should have a setArray method that allows you to set the â??aâ?? variable. WrapperShallow should have an invalid copy constructor. public WrapperShallow(WrapperShallow ws){ a = ws.a; } WrapperDeep should have a properly functioning copy constructor. public WrapperDeep(WrapperDeep ws){ a = new int[3]; for(int i = 0; i < 3; i++) a[i]=ws.a[i]; } Think about why shallow is wrong and deep is correct! What happens to the old â??aâ?? in the WrapperDeep copy constructor? (think garbage collection) Example Output: --------------------Configuration: -------------------- **** TESTING SHALLOW OBJECTS **** inital shallow object contains 7 17 77 copy shallow object contains 7 17 77 inital shallow object changed to 13 14 15 copy shallow object not changed contains 13 14 15 WOOPS! ws.equals(ws2) is true **** TESTING DEEP OBJECTS **** inital deep object contains 2 3 4 copy deep object contains 2 3 4 inital deep object changed to 7 6 -5 copy deep object not changed contains 2 3 4 RIGHT! wd.equals(wd2) is false Process completed.
