I am dealing with lot of double values in my application, is there is any easy way to handle the formatting of decimal values in Java?
Is there any other better way of doing it than
DecimalFormat df = new DecimalFormat("#.##");
What i want to do basically is format double values like
23.59004 to 23.59
35.7 to 35.70
3.0 to 3.00
9 to 9.00
This question is related to
java
An alternative is to use String.format
:
double[] arr = { 23.59004,
35.7,
3.0,
9
};
for ( double dub : arr ) {
System.out.println( String.format( "%.2f", dub ) );
}
output:
23.59
35.70
3.00
9.00
You could also use System.out.format
(same method signature), or create a java.util.Formatter
which works in the same way.
