Java 5 Extra practice and review not about naming and scope

Java:

5. Extra practice and review (not about naming and scope): Write a class TriangleTable. A TriangleTable is defined by an integer n > 0. There are n rows in the table. Row i (starting from 0) contains the numbers from i down to 0. For example, a TriangleTable of size 4 would look like the following: 1 0 2 1 0 3 2 1 0 Your class should have a method that prints the instance nicely (like above). Your program should create and print tables of size from 1 to 10.
