Real-Life Example

Here’s a practical demonstration illustrating the utilization of various data types to compute and display the total cost of a specified quantity of items:

Example

// Create variables of different data types

int items = 50;

float costPerItem = 9.99f;

float totalCost = items * costPerItem;

char currency = ‘$’;

// Print variables

System.out.println(“Number of items: “ + items); System.out.println(“Cost per item: “ + costPerItem + currency); System.out.println(“Total cost = “ + totalCost + currency);
