Real-Life Example

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);
