Problem
A store wants to manage its inventory of products across 3 branches.
Write a program that will:
- Use a 2D array to store the stock quantities of each product in each branch.
- Allow the user to input the stock quantities for all products in all branches.
- Display the stock quantities in a tabular format.
Calculate and display:
Total stock of each product across all branches.
Total stock in each branch.
The overall stock in the store.
Code
package case1;
import java.util.Scanner;
public class Case1 {
public static void main(String[] args) {
Scanner kb = new Scanner(System.in); // Create a Scanner object for input
int[][] stock = new int[4][3]; // 2D array to store stock quantities for 4 branches and 3 products
// Input stock quantities
for (int branch = 0; branch < 4; branch++) { // Loop through each branch
System.out.println("Enter stock quantities for Branch " + (branch + 1) + ":");
for (int product = 0; product < 3; product++) { // Loop through each product
System.out.print("Product " + (product + 1) + ": ");
stock[branch][product] = kb.nextInt(); // Read stock quantity for the current product in the current branch
}
}
// Display stock quantities in tabular format
System.out.println("\nStock quantities:");
System.out.println("Branch\tProduct 1\tProduct 2\tProduct 3");
for (int branch = 0; branch < 4; branch++) { // Loop through each branch
System.out.print("Branch " + (branch + 1) + "\t");
for (int product = 0; product < 3; product++) { // Loop through each product
System.out.print(stock[branch][product] + "\t\t"); // Print stock quantity for the current product in the current branch
}
System.out.println(); // Move to the next line after printing all products for the current branch
}
// Calculate and display total stock of each product across all branches
int[] totalProductStock = new int[3]; // Array to store total stock for each product
for (int product = 0; product < 3; product++) { // Loop through each product
for (int branch = 0; branch < 4; branch++) { // Loop through each branch
totalProductStock[product] += stock[branch][product]; // Add stock quantity of the current product from the current branch to the total
}
}
System.out.println("\nTotal stock of each product across all branches:");
for (int product = 0; product < 3; product++) { // Loop through each product
System.out.println("Product " + (product + 1) + ": " + totalProductStock[product]); // Print total stock for the current product
}
// Calculate and display total stock in each branch
int[] totalBranchStock = new int[4]; // Array to store total stock for each branch
for (int branch = 0; branch < 4; branch++) { // Loop through each branch
for (int product = 0; product < 3; product++) { // Loop through each product
totalBranchStock[branch] += stock[branch][product]; // Add stock quantity of the current product froma the current branch to the total
}
}
System.out.println("\nTotal stock in each branch:");
for (int branch = 0; branch < 4; branch++) { // Loop through each branch
System.out.println("Branch " + (branch + 1) + ": " + totalBranchStock[branch]); // Print total stock for the current branch
}
// Calculate and display the overall stock in the store
int overallStock = 0; // Variable to store overall stock
for (int branch = 0; branch < 4; branch++) { // Loop through each branch
for (int product = 0; product < 3; product++) { // Loop through each product
overallStock += stock[branch][product]; // Add total stock of the current branch to the overall stock
}
}
System.out.println("\nOverall stock in the store: " + overallStock); // Print overall stock
kb.close(); // Close the Scanner object
}
