I have a simple question, but it's rather difficult to google. I have an input field for a number, and I need to make this number into a currency. So, if a user inputs 120, I need to format that into $1.20. Then, if they add another digit, say the number becomes 1204, I need to format this as $12.04. I'm using a Double.ParseDouble, but for say 120, this yields $120.00. So, I guess I need something like ParseDouble that will turn a value like 120 into $1.20 instead of $120.00. How do I do this?

use Double.parseDouble(double number);, but easily multiply with 0.01 :)
Then you have your currency and everything is fine ;)

You can do it without even parsing in a numeric.
Use a StringBuilder object to do so:
String input = "120";
String output = new StringBuilder(input).insert(input.length() - 2,".")
.insert(0, "$").toString();
System.out.println(output); // Prints $1.20
public String getNumberCurrency(double number){
NumberFormat formatter = NumberFormat.getCurrencyInstance(Locale.getDefault());
String moneyString = formatter.format(number/100);
return moneyString;
}
