Hello, if anyone can help I'd greatly appreciate any input! I am of course another newbie and attempting to compile the Inventory program - it contains arrays and I am trying to create a method to calculate the total inventory which is contained within the array named sumInventory[]
Here's the inventorypart2 class this contains the arrays.
public class InventoryPart2 {
// main
public static void main(String[] args) {
// welcome screen
System.out.println("Welcome to Inventory Program Part 2");
System.out.println();
System.out.println();//blank line
System.out.println("***Inventory Items***");
System.out.println();
// create and intialize ProductsPart2 object
ProductsPart2 p1 = new ProductsPart2(1, "Pens", 50, 1.50);
ProductsPart2 p2 = new ProductsPart2(2, "Pencils", 25, 0.25);
ProductsPart2 p3 = new ProductsPart2(3, "Hammer", 15, 12.00);
ProductsPart2 p4 = new ProductsPart2(4, "Tape", 15, 10.45);
ProductsPart2 p5 = new ProductsPart2(5, "Paper", 25, 7.95);
ProductsPart2 p6 = new ProductsPart2(6, "Scissors", 6, 4.25);
//declare and intitialize the arrays & specifies elements
int itemNumber[] = { 1, 2, 3, 4, 5, 6};
int numUnits[] = { 50, 25, 15, 15, 25, 8};
double priceUnits [] = {1.50, .25, 12.00, 10.45, 7.95, 4.25};
String prodName[] = {"Pens", "Pencils", "Hammer", "Tape", "Paper", "Scissors"};
// double calculateInventory[] = {p1.calculateInventory(),p2.calculateInventory(), p3.calculateInventory(),
// p4.calculateInventory(), p5.calculateInventory(), p6.calculateInventory()};
double sumInventory[] = {75, 6.25, 180, 156.75, 198.75, 25.50};
//displays the array unsorted
for(int i = 0; i < 6; i++){
System.out.printf("Item Name: %s\n" , prodName[i]);//product number display
System.out.printf("Item Number: %s\n", itemNumber[i]);//item number display
System.out.printf("Number of units: %s\n", numUnits[i]); // number of units dipslay
System.out.printf("Price per unit: $%6.2f\n", priceUnits[i]);//price per unit display
System.out.printf("Inventory value: $ %.2f\n", sumInventory[i]);//inventory value for that product
System.out.println();
}// end display loop method
//display total inventory value
System.out.printf("Value of Total inventory: $%%.2f\n", ProductsPart2.getTotalValue());
System.out.println();//blank line
System.out.println("****End Of Program****");//end message
} //end class InventoryPart2
}// end mainHere is the ProductPart2 class that contains the calculation method that is erroring out.
public class ProductsPart2 {
private int itemNumber;//item number
private String prodName;//product name
private int numUnits;//number of units
private double priceUnit;//price per unit
public double inventory;//value of inventory
// constructor
public ProductsPart2(int itemNumber, String prodName, int numUnits, double priceUnit)
{
this.itemNumber = itemNumber;
this.prodName = prodName;
this.numUnits = numUnits;
this.priceUnit = priceUnit;
}//end of constructor
// calculate the value of inventory
public double calculateInventory() {
inventory = priceUnit * numUnits;
return inventory;
}//end calculate method
// get and return itemNumber
public int getItemNumber() {
return itemNumber;
}
//method to set itemNumber
public void setItemNumber(int itemNumber) {
this.itemNumber = itemNumber;
}//end method to setitem number
//get and retun prodName
public String getProdName() {
return prodName;
}//end method getProdName
//method to set prodName
public void setProdName(String prodName) {
this.prodName = prodName;
}//end method set itemName
//get and return numUnits
public int getNumUnits() {
return numUnits;
}//end method getNumUnits
//method to setnumunits
public void setNumUnits(int numUnits) {
this.numUnits = numUnits;
}//end method setnumUnits
// get return the price of units
public double getPriceUnit() {
return priceUnit;
}//end method getPriceUnit
//method to setPriceUnit
public void setPriceUnit(double priceUnit) {
this.priceUnit = priceUnit;
}//end method setPriceUnit
// returns it as a string
public String toString() {
return String.format(" %03d %10s %3d $%6.2f $%7.2f",
itemNumber, prodName, numUnits, priceUnit, calculateInventory());
}//ends tostring
//an attempt to get total out of the array don't work
public double getTotalValue(){//method to get total value of all inventory
double value = 0.00;//initialize total
//loop through array
for (int i = 0; i < 6; i++)
{
value += sumInventory[i];
}//end for
return value;
}//end method to get total value of all
//method to sort by name
}//end class ProductI'm getting several errors right now but I'm just worried about getting the totalValue working for now. I believe the culprit is in red and can't figure out why? It is supposed to run through the sumInventory array and add all the vales. then in the InventoryPart2 class it supposed to grab the totalValue variable to display it.
Any input good or bad is appreciated - Thanks
