There are many ways of doing this lab. Go for the solution closer to your Java skills. The most basic way is a series of “if” statements.

Set 1 task(s): Create three students using the "Set 1" data shown below. Prefix this output with two lines. On line one, output "Set 1". On line two, output twenty hyphens. Then, display all class variables of each student. After ensuring desired results are present, apply a single-line comment to introduce the logic you wrote as: // Set 1 task(s)...

Set 2 task(s): Create three more students using the "Set 2" data shown below. Prefix this output with two lines. On line one, output "Set 2". On line two, output twenty hyphens. Then, find and display the name of the youngest of these three students.  After ensuring desired results are present, apply a single-line comment to introduce the logic you wrote as: // Set 2 task(s)...

Set 3 task(s): Create three more students using the "Set 3" data shown below. Prefix this output with two lines. On line one, output "Set 3". On line two, output twenty hyphens. Then, find and display the name of the oldest of these three students. After ensuring desired results are present, apply a single-line comment to introduce the logic you wrote as: // Set 3 task(s)...

By "find" above, I mean using the objects' data and doing calculations instead of you looking at the data and displaying John as the youngest and Fred as the oldest.

Test your solution with the following sets of data:

Set 1	Set 2	Set 3
John Smith 20 Zack Mills 21 Fred Fonz 44	John Smith 33 Zack Mills 22 Fred Fonz 20	John Smith 20 Zack Mills 40 Fred Fonz 30
