Java Format Alternate Conversion
Description
# sets alternate conversion format.
The # can be applied to %o, %x,
%e, and %f.
For %e and %f, the # ensures that there will be a
decimal point even if there are no decimal digits.
Syntax
fmt.format("%#f", 1.0); Example
import java.util.Formatter;
/* w w w . ja va 2 s. c o m*/
public class Main {
public static void main(String args[]) {
Formatter fmt = new Formatter();
fmt.format("%#f", 1.0);
System.out.println(fmt);
}
}
The output:
Example 2
If you precede the %x format specifier with a #,
the hexadecimal number will be printed with a 0x prefix.
import java.util.Formatter;
//w ww. j a va 2s . c o m
public class Main {
public static void main(String args[]) {
Formatter fmt = new Formatter();
fmt.format("%#X", 1);
System.out.println(fmt);
}
}
The output:
Example 3
Preceding the %o specifier with # causes the number to be
printed with a leading zero.
import java.util.Formatter;
/* w w w.j a v a2 s .co m*/
public class Main {
public static void main(String args[]) {
Formatter fmt = new Formatter();
fmt.format("%#o", 1);
System.out.println(fmt);
}
}
