Need help sorting arrays

I am new to java programming and totally lost. Will someone please help me in sorting the arrays in my product class of the following code. Thanks.

import java.util.Scanner;
import java.util.Arrays;
public class Inventory {

public static void main(String[] args)
{
Scanner input = new Scanner( System.in );
boolean isValid = true;//**
String productName;// = "DVD"//++
int productNumber;//++
int onHand;//++
double price;//++
double totalInventory;//++
//int count;
double totInventory;//[] = new double[3];//++
double reStockFee = .05;
double reStockCost = 0;
totalInventory = 0;
int count = 0;

while (isValid)
{
System.out.println ("Enter Product Name. Enter exit to quit program");
productName = input.next();

if (!productName.equalsIgnoreCase ("exit"))//++
{
System.out.println ("Enter Item Number: ");
       productNumber = input.nextInt();
       System.out.println ("Enter number of items in stock: ");
       onHand = input.nextInt();
       System.out.println ("Enter item price: ");
       price = input.nextDouble();
       //compute student grade
       totInventory = (onHand * price);
       reStockCost = (onHand * price * reStockFee);
     //create a new class and pass the values to the method

    Product.getData(productName, productNumber, onHand, price, reStockCost, totInventory, count);//+++
    count++;  //increment the counter to use as the array position in second class//+++
}
else
{
isValid = false;//**

System.out.print ("Item Name" + "\t");

System.out.print ("Item Number" + "\t");

System.out.print ("Items on Hand" + "\t");

System.out.print ("Item Price" + "\t");

System.out.print ("Items Value" + "\t");

System.out.print ("Restock Fee" + "\n");

Product.printArray(count);



Product.modifyArray(pName);
System.out.println ("Thank you, come again.");

break;

}

}

}
}

//Product Class

public class Product {
static int maxlength = 100;
static String pName[] = new String[maxlength];
static int[] iNumber = new int [maxlength];
static int[] iStock = new int [maxlength];

// double totInventory, int count) {
// TODO Auto-generated constructor stub
//}

public static void getData(String productName, int productNumber, int onHand, double reStockCost, double price, double totInventory, int count)
{
  //check that count doesn't exceed maximum array length
  if (count > maxlength)
  {
   System.out.println("DATA OVERLOAD!!!!. YOU CRASHED THE SYSTEM!!!  Program Exiting!");
   System.exit(0);
  }
  else
  {
   //store values in the array
   pName[count] = productName;
   iNumber[count] = productNumber;
   iStock[count] = onHand;
   uPrice[count] = price;
   rStockCost[count] = reStockCost;
   tInventory[count] = totInventory;
   totalInventory += totInventory;
   totreStock += reStockCost;

   }

   }

//print the values in the array
//public static void printAll(int count)
public static void printArray(int count)
{
for (int i=0; i<count; i++ )
{
System.out.printf(pName[i]);
System.out.printf("%15d", iNumber[i]);
System.out.printf("%18d", iStock[i]);

System.out.printf("%10s$%.2f", "", tInventory[i]);
System.out.printf("%10s$%.2f\n","", rStockCost[i]);
}
  System.out.printf("%s$%.2f\n", "Entire Inventory Value: ", totalInventory);
  System.out.printf("%s$%.2f\n", "Entire Inventory Restock Cost: ", totreStock);


}

}



public class modifyArray
{

public static void modifyArray(pName)
{
Arrays.sort(pName1);
System.out.println("Array contents sfter sort:");
for (int i = 0; i < pName.length; i++)
System.out.println(pName1);
}
