本文整理了Java中java.util.Formatter.<init>()方法的一些代码示例，展示了Formatter.<init>()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Formatter.<init>()方法的具体详情如下：
包路径：java.util.Formatter
类名称：Formatter
方法名：<init>

Formatter.<init>介绍

[英]Constructs a Formatter.

The output is written to a StringBuilder which can be acquired by invoking #out() and whose content can be obtained by calling toString.

The Locale used is the user's default locale. See "Be wary of the default locale".
[中]构造一个格式化程序。
输出被写入StringBuilder，该StringBuilder可以通过调用#out（）获得，其内容可以通过调用toString获得。
使用的区域设置是用户的默认区域设置。请参阅“{$0$}”。
