Use of .setPage and .getPage in twitter4j

I'm new to PDE and Java.

I'm working on a sketch that uses twitter4j.

I Understand that .setRpp() sets the number of returns per page and can have a max value of 100.

I see a set of methods .setPage and .getPage but I'm not sure how I use them.

Can I use them to get more than 100 returns at a time? That is can I get 100 returns on page1 and another 100 returns on page2?

Would I then (in pseudocode)?:

Set returns per page to 100

Set page = 1

Make query

Set page = 2

Repeat query

Set page = 1

Get query results on page 1

Set page = 2

Get the query results on page 2

Can someone please explain the concept of pages? I've seen them in other places.

Thanks!
