How do I do this in Java Eclipse?

Part $1$

Write an application containing three parallel arrays that hold $10$ elements each.$$ The first array hold four$-$digit student ID numbers, the second array holds first names, and the third array holds the students$$ grade point averages.$$ Use dialog boxes to accept a student ID number and display the student$$s first name and grade point average.$$ If a match is not found, display an error message that includes the invalid ID number and allow the user to search for a new ID number.

Part $2$

Create an application that contains an enumeration $($enum$)$ that represents the days of the week.$$ Display a list of the days, then prompt the user for a day. Display business hours for the chosen day.$$ Create your own business hours stored in an array; however, every day of the week should have different hours.$$ Although companies do not normally have different business hours every day of the week, programming your code with this difference will help in finding and fixing coding errors.
