The tutor continues with the potentially tricky topic of Java decimal formatting.<\/h1>\n

 
\nWith yesterday’s post<\/a> I broke the ice about Java DecimalFormat with a short demonstration program. Now, some key points of explanation:<\/p>\n

    \n
  1. The format descriptor string “#,###.00” means that two decimal places will always be shown, even if they are zeros. However, the number 0.79<\/span> will display as .79<\/span> (no zero in front of the decimal point). A “#” means that the place will not be shown if it is a leading or trailing zero, whereas a “0” means the place will be shown, with a zero if it has no other value. Therefore, the number 2, formatted as “#0,000.00”, will be rendered as 0,002.00 by DecimalFormat.<\/li>\n

    <\/p>\n

  2. Notice that the output of DecimalFormat is a string (that looks like a number<\/em>).<\/li>\n

    <\/p>\n

  3. The Scanner is not intrinsically connected to DecimalFormat; it is used in the program to read the numbers from the command line.\n<\/li>\n<\/ol>\n

    While this probably covers the program from yesterday, there is still more to say about Java’s DecimalFormat. Not surprisingly, I’ll be continuing about it in future posts:)<\/p>\n
