Formatting a Number

  Asked By: Willie    Date: Jan 27    Category: Java    Views: 978

I'd like to format a Number, say, a float or a double, as a String in
the Format 999,999.99 and then display it.

How can this be done ?

Thanks for the reply.

toString returns a default String. As far as I am aware, it does not
provide the flexibility to format  this String in a programmer-
specifiable manner.

I really wanted to ask if there is a ready-made method to format a
number in a programmer-specifiable manner.

You can use the java.text package. It provides a variety of formats.

You should use the class java.text.DecimalFormat. I haven't used it
myself, so I can't help you much more, but this is probably the class
you need.

Here is a quick example:

import java.text.DecimalFormat;

class Format{
public static void main(String[] args){
String input = "12345678.2";
DecimalFormat formatter = new
String s = formatter.format(
Double.parseDouble(input) );
System.out.println( s );
