I am trying to format a string whereby the '$' stick close to the price.
For example:
Oranges 3 $3.00 $9.00
But what I currently have:
Oranges 3 $ 3.00 $ 9.00
This is my code: (Note: "price" and "total" are double datatype)
System.out.printf("%-25s %10s $%10s $%10s", item, quantity, price, total);
I want to have a gap in between every output but I can't find a way to get the result that I wanted. Is there any ways to solve this?
try
System.out.printf("%-25s %10s %10s %10s", item, quantity, "$" + price, "$" + total);
output
Oranges 3 $3.0 $9.0
or, best of all, use a formatter method
String format(double d) {
return String.format("$%.2f", d);
}
...
System.out.printf("%-25s %10s %10s %10s", item, quantity, format(price), format(total));
output
Oranges 3 $3.00 $9.00
Could you just convert them to a String for output? The Double type can have the toString() method called on it, as per this link:
http://www.java2s.com/Code/Java/Language-Basics/Convertdoubletostring.htm
And then you can just output a dollar symbol at the top of each string (you could even loop through all the strings if you load them into an array, and add a dollar symbol to all of them).
This might not be the best option, but I'm sure it'll work.
