More specific question about my topic...
public class Item implements Comparable
{
private int myId;
private int myInv;
public Item(int id, int inv)
{
myId = id;
myInv = inv;
}
public int getId(){ )
public int getInv(){ }
public int compareTo(Object otherObject){ }
public boolean equals(Object otherObject){ }
public String toString(){ }
}
public class Store
{
private Item[] myStore;
public Store(String fileName) { }
public void displayStore()
public String toString(){ }
public void doSort() { }
private void quickSort(Item[] list, int first, int last)
private void loadFile(String inFileName)
}
The first line of file50.txt contains the number of id/inventory integer pairs listed on subsequent lines. The idea behind the data type item is the simulation of an item in a store, nearly all of which use a bar code for identification purposes. For every item in a store we keep track of an id value and an inventory amount. So file50.txt looks like this:
50
3679 87
196 60
17914 12
18618 64
2370 65
... ...
etc. (for 45 more lines)
Each id value in file50.txt will be unique.
Assignment:
Write a program that solves the following sequential events:
loads the data file, file50.txt, as a collection of Item types maintained in a Store object
sorts the data using quickSort
prints the data , now in increasing order based on the id field of an Item object
The printing should add a blank line after every 10 items in the output. Include a line number in the output. For example:
Id Inv
1 184 14
2 196 60
3 206 31
4 584 85
5 768 85
6 2370 65
7 3433 5
8 3679 87
9 4329 64
10 5529 11
11 6265 58
12 6835 94
13 6992 76
14 7282 73
15 8303 90
16 9267 68
I really have no Idea what to put for getId(), getInv(), and
the constructor Store
public Store(String fileName) { }
?
please.. please help me..
