All 7 community colleges in the State of Hawai`i are a part of the University of Hawai`i system. We do not have junior colleges here.

Yay for Wikipedia:

Since many public junior colleges in the United States served a more localized community, these schools began to replace the "junior" in their names with "community". With the advent of the term community college for public institutions, in the United States the term junior college is often explicitly used to refer to private institutions. However, the relative small number of private junior colleges and the continued use of the term in the names of many community colleges means that people often do not perceive a distinction between the two terms, and thus they are interchangeable in casual speech.
