I am trying to put together a simple inventory program for my class, but I keep running into one error that I just cannot seem to correct.
Here is my code:
public class DVD extends Product {
// channel that the show was on
private String channel;
// constructor
public DVD(int item, String name, int units, double price, String channel) {
super(item,name,units, price);
this.channel = channel;
}
// getter
public String getChannel() {
return channel;
}
// setter
public void setChannel(String channel) {
this.channel = channel;
}
// total value with the 5% fee
public double value() {
return super.value()*1.05;
}
// the 5% fee
public double fee() {
return super.value()*0.05;
}
public String toString () {
return super.toString() + "\n" +
"Channel: " + channel +
"\nFee (already included in value): " +
String.format("$%.2f", fee());
}
}
public class Inventory {
private DVD[] list;
// constructor
public Inventory(int size) {
list = new DVD[size];
}
public int size() {
return list.length;
}
// complete value
public double totalValue() {
double val = 0.0;
for (int i = 0; i < list.length; i++) {
val += list[i].value();
}
return val;
}
// add an item
public void add(DVD d, int p) {
list[p] = d;
}
// get an item
public DVD get(int i) {
return list[i];
}
// sort by name
public void sort() {
// bubble sort
int n = list.length;
for (int search = 1; search < n; search++) {
for (int i = 0; i < n-search; i++) {
if (list[i].getdvdName().compareToIgnoreCase(list[i+1].getdvdName()) > 0) {
// swap
DVD temp = list[i];
list[i] = list[i+1];
list[i+1] = temp;
}
}
}
}
}
import java.awt.event.*
import javax.swing.*;
// stores TV DVD's
class InventoryProgram extends JFrame {
private JTextArea txt;
private Inventory obj;
private int current = 0;
private JButton next;
public static void main(String args[]) {
InventoryProgram gui = new InventoryProgram();
gui.pack();
gui.setVisible(true);
}
public InventoryProgram() {
super("TV DVD's");

/// output

System.out.println(obj.get(i));
System.out.println();
}
// total val
System.out.printf("Total value: $%.2f", obj.totalValue());
// gui stuff
JPanel panel = new JPanel();
txt = new JTextArea(15,20);
txt.setEditable(false);//user shouldn't change it
panel.add(txt);
next = new JButton("Next");
next.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if (current < obj.size()-1) {
current++;
showMusic();
if (current == obj.size()-1) {
InventoryProgram.this.next.setEnabled(false);
}
}
}
});
panel.add(next);
getContentPane().add(panel);
showMusic();
}
public void showMusic() {
txt.setText("DVD Details:\n");
txt.append(obj.get(current) + "\n");
txt.append("Total value: $" + String.format("%.2f",obj.totalValue()));
}
}
// product class
public class Product {
// variables
private int itemNumber;
private String dvdName;
private int units;
private double price;
// constructor for the product
public Product(int itemNumber, String dvdName, int units, double price) {
this.itemNumber = itemNumber;
this.dvdName = dvdName;
this.units = units;
this.price = price;
}
// total value
public double value() {
return units*price;
}
// getters and setters
public int getitemNumber() {
return itemNumber;
}
public void setitemNumber(int itemNumber) {
this.itemNumber = itemNumber;
}
public String getdvdName() {
return dvdName;
}
public void setdvdName(String dvdName) {
this.dvdName = dvdName;
}
public int getUnits() {
return units;
}
public void setUnits(int units) {
this.units = units;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
public String toString () {
return "Item number: " + itemNumber
+ "\nName: " + dvdName+ "\nUnits: " + units
+ "\nPrice: " + String.format("$%.2f", price)
+ "\nValue: " + String.format("$%.2f", value());
}
}
And the error I get is:
C:\Documents and Settings\Administrator\Desktop\InventoryProgram.java:94: class, interface, or enum expected
import java.awt.event.*
^
1 error
Tool completed with exit code 1
What am I missing here? I've tried several things and nothing works.
