Make 2 classes WrapperShallow and WrapperDeep.

Question

Each class shallow and deep are simply wrapper classes to hold a private array variable. int [] a;

The default constructor for each class should initialize “a”.

Each class should have a toString() and equals(). Each class should have a setArray method that allows you to set the “a” 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];

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.
