如何在Java中将长整数格式化为不带分隔符的字符串？

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

简单的问题，但我敢打赌，在这里询问可能比试图理解MessageFormat的文档更直截了当：

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

Observed value is "12,345".

观察值为“12,345”。

Desired value is "12345".

期望值是“12345”。

5 个解决方案

#1

Just use Long.toString(long foo)

只需使用Long.toString（long foo）

#2

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

#3

The shortest way is

最短的路是

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

#4

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

作为替代方案，String.format和java.util.Formatter可能也适合你...

#5

You could try:

你可以尝试：

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