Shopping Cart V1 - Single Item Total in Java

Practice

Practice variables, arithmetic, and string concatenation by printing a tiny one-item receipt.

You start with:

String item = "Coffee Mug";
int price = 12;
int quantity = 3;

Build:

Coffee Mug x3
Total: $36

Rules:

Compute total = price * quantity.
First line: "<item> x<quantity>" (e.g. "Coffee Mug x3").
Second line: "Total: $<total>".
Join the two lines with a newline "\n" into one string result, then print it with System.out.println(result).

Java's + on a String and an int converts the integer to text for you.

line1 + "\n" + line2 joins both lines into one string.

String item = "Coffee Mug";
int price = 12;
int quantity = 3;

int total = price * quantity;
String line1 = item + " x" + quantity;
String line2 = "Total: $" + total;
String result = line1 + "\n" + line2;
System.out.println(result);
