Some interfaces have "hidden" modes. for example, for some half-open garage doors, the user cannot predict, without knowing some of the history of the interaction, whether a button press will cause it to go up or go down. what principle of direct manipulation is violated by such hidden modes?

Create a class named majors that includes an enumeration for the six majors offered by a college as follows: acc, chem, cis, eng, his, phys. display the enumeration values for the user, then prompt the user to enter a major. display the college division in which the major falls. acc and cis are in the business division, chem and phys are in the science division, and eng and his are in the humanities division. save the file as majors.java.
