This program calculates change for a purchase.

• Static variables keep track of item price, amount tendered, and remaining change.
• Methods help isolate functional components.

• Double types defaulted to many decimal places when performing operations, which provided too fine of a precision in regards to currency with two decimal places.
• The DecimalFormat object provided a way to define the decimal places required: DecimalFormat df = new DecimalFormat("#.00")
• Converting the DecimalFormat back to Double helped continue with the calculation: remaining = Double.valueOf(df.format(remaining))

• JavaSE-1.8
• Eclipse IDE
