Java Programming Question: I am trying to convert my original code into object programming language using objects and constructors and I am having trouble. My my new code with many errors is listed below.

Program Overview: This program calculates the cost of University tuition for one year (2 semesters and 1 summer) for

undergraduate and graduate students (resident, non-resident, and international students) based on various menu options. Input: type of student (full-time or part-time), number of credits, summer student, number of additional summer credits, number of rooms for housing (0,1, or 2), meal plan, and a menu option. Output: cost of University tuition for one year for undergraduate and graduate students (resident, non-resident, and international students). */
