Question about decimal alignment
|
|
|
| I am writing a program for my class and part of the out is a series of
numbers with 2 decimal places. How do I get the decimal places to line
up?
I get alignment that looks like:
775.00
30.25
1.15
When what I want is:
775.00
30.25
1.15
alined.
The snippit of code is:
System.out.printf( "\n DVD Results\n");
System.out.printf( "DVD Title Qty Cost
Value\n");
System.out.printf(
"-------------------------------------------------------" );
for (int i = 0; i < index1; i++)
{
// Display DVD details
System.out.printf( "\n%-5s",id[i] );
System.out.printf( " %-25s",name[i] );
System.out.printf( " %3.0f",qty[i]);
System.out.printf( " %-4.2f",each[i]);
System.out.printf( " %6.2f",total[i]);
}
System.out.printf(
"\n-------------------------------------------------------\n" );
System.out.printf( "
%6.2f",gtotal1 );
System.out.printf( "\n
==================\n" );

For formatting using the %f notation, remember that the format is
<width>.<precision>, where width is the total width of the field and
precision is the number of decimal places.
So for outputting 775.00 you need at least a width of 6.
