Explanation of Solution
Reasons for causing an error message:
- • From the given code, the variables “s1” and “s2” are names of objects of “Species” type; however this program does not create any objects for two names “s1” and “s2” which are just names not objects.
- ○ Hence, it displays an error message.
- • Object declaration for “Species” class will be as follows:
Species s1 = new Species();
Species s2 = new Species();
Correction code:
//Define class "SpeciesEqualsDemo"
public class SpeciesEqualsDemo
{
//Define main function
public static void main(String[] args)
{
//Create "s1" object for "Species" class
Species s1 = new Species();
...
