Here's a real-life example of using different data types, to calculate and output the total cost of a number 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);
