Hi All,
Can anyone tell me if java has a way to format a string to display in a certain way always. For instance i have
publicclass foo
{
publicstaticvoid main (String[] args)
{
String Number1="12345";
String Number2="123";
}
}
And i want both String when print to print with six digits and leading zeroes to fill in. For example Number1 would print 012345 and Number2 000123
Thanks for the help!
use NumberFormat http://java.sun.com/j2se/1.4.2/docs/api/java/text/NumberFormat.html
import java.text.*;
public class foo
{
public static void main (String[] args)
{
String Number1="12345";
String Number2="123";
try{
double d = Double.parseDouble(Number1);
NumberFormat formatter = new DecimalFormat("000000");
String s = formatter.format(d);
System.out.println(s);
}catch(Exception e){
e.printStackTrace();
}
}
}
If I'm not mistaken, the leading zero's can only be added in from of numbers, not Strings (when using the printf(...) method):int number1 = 12345;
int number2 = 123;
System.out.printf("%06d\n%06d", number1, number2);
