Explanation of Solution
ResultSet:
- The “SELECT” statement is been used for selecting data from a
database . - The result table is stored with data and is termed as “ResultSet”.
- A “ResultSet” object contains a set of rows as well as columns.
- All the fields present in table could be selected using “SELECT” statement.
- Specific fields can be selected by giving particular field names in “SELECT” statement.
Initial cursor position of ResultSet object:
- After execution of a “SELECT” statement, a “ResultSet” is opened.
- The cursor in “ResultSet” object denotes to beginning of “ResultSet” data.
- It is present just before first row of table.
- The cursor should be moved to first row for reading data from first row.
- The row that cursor points to is considered as current row.
- The cursor should be moved from row to row and it helps to examine all rows in “ResultSet”...

- Object-Oriented Programming In this separate files. ent, you'll need to build and run a small Zoo in Lennoxville. All classes must be created in Animal (5) First, start by building a class that describes an Animal at a Zoo. It should have one private instance variable for the name of the animal, and one for its hunger status (fed or hungry). Add methods for setting and getting the hunger satus variable, along with a getter for the name. Consider how these should be named for code clarity. For instance, using a method called hungry () to make the animal hungry could be used as a setter for the hunger field. The same logic could be applied to when it's being fed: public void feed () { this.fed = true; Furthermore, the getter for the fed variable could be named is Fed as it is more descriptive about what it answers when compared to get Fed. Keep this technique in mind for future class designs. Zoo (10) Now we have the animals designed and ready for building a little Zoo!
