1.packageanimals.fish；
2.
3.public class Salmon extends Fish{
4.voidconsume（）{/*dostuff*/}
5.}

B.add public to the start of line 4 in GrizzlyBear.java
C.add import animals.mammals.*；at line 2 in Salmon.java
D.add import animals.fish.*at line 2 in GrizzlyBear.java
E.add import animals.fish.Salmon.*；at line 2 in GrizzlyBear.java
