Question

Write a class in java for objects that store information about fish. For each fish you need to store its breed (a string) and whether or not it is edible (a boolean). Provide a default conStructor, and an initial value constructor that accepts the breed as its parameter. The initial value conStructor must call the default constructor. By default a fish is not edible. Provide JUSt one mutator method that receives a string parameter, and sets the edible variable to true if the parameter is the fish's breed.

Answer 1

public class Fish {

   // instance variables
   private String breed;
   private boolean edible;
  
   // default constructor
   public Fish()
   {
       breed = "";
       edible = false;
   }
  
   // initial value constructor
   public Fish(String breed)
   {
       this();
       this.breed = breed;
   }
  
   // mutator method
   public void setEdible(String inBreed)
   {
       if(breed.equalsIgnoreCase(inBreed)) //check if inBreed is same as breed then set edible to true
           edible = true;
   }

}
