How do I format a long integer as a string without separator in Java?

Question

Simple question, but I'll bet that asking on here will probably be more straight forward than trying to understand the documentation for MessageFormat:

long foo = 12345;
String s = MessageFormat.format("{0}", foo);

Observed value is "12,345".

Desired value is "12345".

Answer 1

Just use Long.toString(foo)

Answer 2

Take a look at (http://coffeaelectronica.com/blog/2009/11/messageformat-goodies/) line 23 of the code example shows the custom number format. For your case you can just use #### and it should avoid adding commas.

Hope this helps.

Answer 3

MessageFormat.format("{0,number,#}", foo);

Answer 4

As an alternative String.format and java.util.Formatter might work for you as well...

Answer 5

You could try:

String s = new Long(foo).toString();

Answer 6

The shortest way is

long foo = 12345;
String s = ""+foo;
