You are provided with the class Person, and five one-dimensional arrays of Person, and required to combine them into a two-dimensional array The data represents a list of appointments for five days of the week. Each array contains the people scheduled for one day's appointment. Follow the directions exactly, and in order Task #1 Find an element of a 1D array l. Using the existing ID array called tuesdayAppts, find Person p7 2. Set intToPrint as the ID of Person p7, using tuesdayAppts and the accessor found in the file Person java. Do not access p7 directly 3. Set fNameToPrint and lNameToPrint of Person p7 4. Run the program to see the result. Task #2 Create a 2D Array l. Declare a2D array called weeklyAppts 2. Instantiate weeklyAppts using the five daily appointment ID arrays. Task #3 Find an element of a 2D array l. Using the 2D array called weeklyAppts, find Person #8 (p8). 2. Set intToPrint as the ID of Person p8, using weeklyAppts. 3. Set fName ToPrint and lNameToPrint of Person p8. 4. Run the program to see the result. Task #4 Find the length of a 1D array in a 2D array l. Using weeklyAppts, set int ToPrint to the length of thursdayAppts 2. Run the program to see the result
