Someone already answered Task#1 question. There is a Person class.

I'm stuck on Task #2 and have include my code below: - infact I probably will need help with the other task. Liking Java so far, arrays - not so much.

import java.text.*; // to use Decimal Format

public class TwoD_ArrayDriver

{

public static void main(String[] args)

{

DecimalFormat myFormat;

// to get 2 decimals every time

myFormat = new DecimalFormat("#.00");

Person p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12, p13, p14, p15, p16, p17, p18, p19, p20, p21;

p1 = new Person("Abby", "Arthur"); p2 = new Person("Bubba","Brown"); p3 = new Person("Chuckie", "Cheese"); p4 = new Person("Don", "Drysdale"); p5 = new Person("Ernie","Eastwood");

p6 = new Person("Flo", "Fauntroy"); p7 = new Person("Gabby", "Giffords"); p8 = new Person("Hank","Hoover"); p9 = new Person("Indy", "Imhauf"); p10 = new Person("Jim","Jones");

p11 = new Person("Ken", "Koopman"); p12 = new Person("Larry", "Lancelot"); p13 = new Person("Michael", "Moore" ); p14 = new Person("Nina","Nonesuch"); p15 = new Person("Oscar","OToole");

p16 = new Person("Pat","Pompous"); p17 = new Person("Quincy","Quinton"); p18 = new Person("Ralph","Rancid"); p19 = new Person("Steven","Simpson"); p20 = new Person("Tim","Tinker");

p21 = new Person("Uncle","Usher");

Person[] allPersons = {p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12, p13, p14, p15, p16, p17, p18, p19, p20, p21};

Person[] mondayAppts = {p1, p2, p3, p4, p5};

Person[] tuesdayAppts = {p6, p7, p8};

Person[] wednesdayAppts = {p9, p10, p11, p12};

Person[] thursdayAppts = {p13, p14, p15, p16, p17};

Person[] fridayAppts = {p18, p19, p20, p21};

//Task #1 Print the id, first name, and last name of Person #7, using tuesdayAppts

int intToPrint = 0;

String fNameToPrint = "unknown";

String lNameToPrint = "unknown";

System.out.println("Person #7 "+ p7.ID +" "+ p7.fName + " "+ p7.lName);

//Task #2 Create a 2D array out of the 1D arrays

//begin my code.

Person [][] weeklyAppts = new Person [5][5];

for (int row= 0; row < 5; row ++) //days of week

{

for (int col = 0; col < 5; col ++) //persons

{

weeklyAppts [row] [col] = ??????

}

} //end my code

//Task #3 Print the id of Person #8, using weeklyAppts

intToPrint = 0;

fNameToPrint = "unknown";

lNameToPrint = "unknown";

System.out.println("Person #8's ID "+intToPrint+" "+ fNameToPrint +" "+lNameToPrint);

//Task #4 Print the length of thursdayAppts using weeklyAppts

intToPrint = 0;

System.out.println("Length of Thursday's appts "+intToPrint);

//Task #5 Print all using weeklyAppts

int ctr = 1;

for (int i=0; i<2; i++) {

for (int j=0; j<2; j++) {

intToPrint = 0;

fNameToPrint = "unknown";

lNameToPrint = "unknown";

System.out.println("Appt #"+(ctr++)+" "+intToPrint+" "+fNameToPrint+" "+lNameToPrint);

}

}

}

}

The Person Class;

public class Person {

String fName;

String lName;

int ID;

static int nextID = 101;

Person() {

fName = "unk";

lName = "unk";

ID = nextID++;

}

Person(String fName, String lName) {

this.fName = fName;

this.lName = lName;

ID = nextID++;

}

public void setFName(String fName) {

this.fName = fName;

}

public String getFName() {

return fName;

}

public void setLName(String lName) {

this.lName = lName;

}

public String getLName() {

return lName;

}

public int getID() {

return ID;

}

}
