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

Question

A simple question, but I bet that the question here will probably be more direct than trying to understand the documentation for MessageFormat :

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

The observed value is "12.345".

The required value is "12345".

Answer 1

Just use Long.toString(long foo)

Answer 2

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

Answer 3

As an alternative, String.format and java.util.Formatter can work for you String.format ...

Answer 4

The shortest way is

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

Answer 5

You can try:

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