Reference no: EM13940261

The application as written does not display certain class names included in the instructions as written.

Write an application that stores at least four different course names and meeting days and times in a two-dimensional string array. Allow the user to enter a course name (such as CIS 110) and display the day of the week and times that the course is held (such as Th 330). If the course does not exist, display an error message.
