Create a program for managing inventory data. The class name should be InvTracker, an underscore, and
your NetID run together; for example, if your NetID is abcde6, your class name is InvTracker_abcde6. For
this assignment, we will create the initial class definition with data members, method shells (just headers),
and a second class, InvItem. The design requirements are:
1) InvTracker data members:
a) an array of type InvItem, with no specific size (statement: InvItem items;)
b) an int for the InvItem array size
2) InvTracker methods:
a) inStock: takes a long as a parameter, returns a boolean
b) stockAmount: takes a long as a parameter, returns an int
c) add: takes a long and an int as parameters, returns void
d) remove: takes a long and an int as parameters, returns void
e) delete: takes a long as a parameter, returns void
f) search: takes a String as a parameter, returns an array of type InvItem
(method header: InvItem search(String s))
3) The InvItem class should be placed after and outside the InvTracker class definition, as:
public class InvTracker { // code goes here} class InvItem {//more code goes here}
Note that only the InvTracker class should be public!
4) InvItem data members:
a) a long named id
b) a String named name
c) an int named quantity
5) InvItem methods:
a) get & set methods for id (resp. return or accept a long)
b) get & set methods for name (resp. return or accept a String)
c) get & set methods for quantity (resp. return or accept an int) Additional Constraints
The program should be implemented as a single file and Java class. All data members should be
declared as private; all methods should be declared without any visibility modifiers. Methods that return a
value should return a placeholder value (like -1 or an empty String) to avoid appearing as code errors in
Eclipse. Note that, for this assignment, the program won’t actually run since it doesn’t have a main
method.
