Define generic classes

 

... It's inheritance, it's interface implementation, and I'm so tired and sweaty.

Code:

1. Public abstract class animal
2. {
3. Protected string name;
5. Public string name
6. {
7. Get
8. {
9. Return name;
10. }
11. Set
12. {
13. Name = value;
14. }
15. }
17. Public animal ()
18. {
19. Name = "the animal with no name ";
20. }
22. Public animal (string newname)
23. {
24. Name = newname;
25. }
27. Public void feed ()
28. {
29. Console. writeline ("{0} has been fed.", name );
30. }
32. Public abstract void makeanoise ();
35. }
37. Public class chicken: Animal
38. {
39. Public void layegg ()
40. {
41. Console. writeline ("{0} has laid an egg.", name );
42. }
44. Public chicken (string newname)
45. : Base (newname)
46. {
47. }
49. Public override void makeanoise ()
50. {
51. Console. writeline ("{0} Says 'cluck! '", Name );
52. }
53. }
55. Public class cow: Animal
56. {
57. Public void milk ()
58. {
59. Console. writeline ("{0} has been milked.", name );
60. }
62. Public cow (string newname)
63. : Base (newname)
64. {
65. }
67. Public override void makeanoise ()
68. {
69. Console. writeline ("{0} syas 'moo'.", name );
70. }
71. }
74. Public class supercow: cow
75. {
76. Public void fly ()
77. {
78. Console. writeline ("{0} is flying! ", Name );
79. }
81. Public supercow (string newname)
82. : Base (newname)
83. {
84. }
86. Public override void makeanoise ()
87. {
88. Console. writeline ("{0} says 'Here I come to save the day! '", Name );
89. }
90. }
93. Public class farm <t>: ienumerable <t>
94. Where T: Animal
95. {
96. Private list <t> animals = new list <t> ();
99. // Read-only attribute
100. Public list <t> animals
101. {
102. Get {return animals ;}
103. }
105. // Implement ienumerable <t>. getenumerator ()
     
106. Public ienumerator <t> ienumerable <t>. getenumerator ()
107. {
108. Return animals. getenumerator ();
109. }
110. // Implement ienumerable. getenumerator ()
     
111. Ienumerator ienumerable. getenumerator ()
112. {
113. Return animals. getenumerator ();
114. }
116. Public void makenoises ()
117. {
118. Foreach (T animal in animals)
119. {
120. // Due to constraints
121. Animal. makeanoise ();
122. }
123. }
125. /// <Summary>
126. /// Extract items that are cow or inherited from cow
127. /// </Summary>
128. /// <Returns> </returns>
129. Public farm <cow> getcows ()
130. {
131. Farm <cow> cowfarm = new farm <cow> ();
132. Foreach (T animal in animals)
133. {
134. If (animal is cow)
135. {
136. Cowfarm. Animals. Add (animal as cow );
137. }
138. }
139. Return cowfarm;
140. }
142. Public void feedtheanimals ()
143. {
144. Foreach (T animal in animals)
145. {
146. Animal. Feed ();
147. }
148. }
150. }
