Animal - height : double + Animal(String, int, double, double, char) //name, birthYear, weight, height, gender + getHeight() : double + setHeight(double) : void //if input value is negative set height to -1 + calculateBMI() : double //using pounds and inches BMI = weight / (height2) * 703 + printDetails() : void // prints Animal attributes in the following format: // "Name: %20s | Year of Birth: %4d | Weight: %10.2f | Height: %10.2f | Gender: %c " + toString() : String @Override //see Note1 for format + equals(Object) : boolean @Override //see Note2 for equality checks NOTE1: Format the data for the toString() method as "Name: %20s | Year of Birth: %4d | Weight: %10.2f | Height: %10.2f | Gender: %c " NOTE2: For the equals(Object) method, two Animal objects are considered equal if both have the same values for birthYear, gender, name and if their weight, height values are within .5 of the others weight, height values
