Program to define a class Item containing code and price. Accept this data for five object using array of objects. Display code, price in tabular form and also, display total price of all items

This program demonstrates you the array of objects. Array of object is the collection of objects of the same class. The given syntax will define an array of reference therefore assign object to individual reference in the array to declare the array of object. The syntax to define array of object is:
<class-name>  <array-name> [size];

For example, the following statement will define an array of object having size 6 references to the class Box.
Box  b[6];

The above statement just declare array of objects. For creating an array of objects (allocating memory) you have to write down the following statements
for (int i=0; i<6; i++) {
 b[i]  = new  Box( );
 // Assigning object to individual reference in the array.

You can access the members of particular object by using membership operator like:
b[i].length = 10;
b[i].width = 20;
b[i].height = 30;


class Item {

 String code;
 int price;
 Item(String c,int p) {
  code = c;
  price = p;
 public static void main(String args[])throws IOException
  Item[] I = new Item[5];
  String a;
  int b,total_cost=0;
  BufferedReader br = new BufferedReader(new InputStreamReader(;
  for(int i=0;i<5 ----------="" :="" a="" b="" code="" for="" i="" int="" item="" new="" nter="" otal="" output="" price="+total_cost);

<pre class=" system.out.print="" system.out.println="" t="" tem="" total_cost="total_cost">C:\>javac

   105         95
Total Price = 309


  1. Awesome read. I just passed this onto a buddy who was doing a little research on that. He just bought me lunch because I found it for him! Thus let me rephrase: Thanx for lunch! node js blog platform
