本文整理了Java中java.io.PrintWriter.printf()方法的一些代码示例，展示了PrintWriter.printf()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。PrintWriter.printf()方法的具体详情如下：
包路径：java.io.PrintWriter
类名称：PrintWriter
方法名：printf

PrintWriter.printf介绍

[英]Prints a formatted string. The behavior of this method is the same as this writer's #format(String, Object...) method.

The Locale used is the user's default locale. See "Be wary of the default locale".
[中]打印格式化的字符串。此方法的行为与此编写器的#格式（字符串、对象…）相同方法
使用的区域设置是用户的默认区域设置。请参阅“{$0$}”。
