I need to display a list of items with their prices from an array and would like to align the prices. I almost have it working but needs improvements. Below is the code and the output. Any ideas how to make all prices aligned? So far some work but some don't. Thanks in advance.
System.out.printf("%d. %s \t\t $%.2f\n",
i + 1, BOOK_TYPE[i], COST[i]);
1. Newspaper $1.00
2. Paper Back $7.50
3. Hardcover book $10.00
4. Electronic book $2.00
5. Magazine $3.00
You can try the below example. Do use '-' before the width to ensure left indentation. By default they will be right indented; which may not suit your purpose.
System.out.printf("%2d. %-20s $%.2f\n", i + 1, BOOK_TYPE[i], COST[i]);
