本文整理了Java中java.util.logging.Formatter类的一些代码示例，展示了Formatter类的具体用法。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类的具体详情如下：
包路径：java.util.logging.Formatter
类名称：Formatter

Formatter介绍

[英]Formatter objects are used to format LogRecord objects into a string representation. Head and tail strings are sometimes used to wrap a set of records. The getHead and getTail methods are used for this purpose.
[中]格式化程序对象用于将日志记录对象格式化为字符串表示形式。头字符串和尾字符串有时用于包装一组记录。getHead和getTail方法用于此目的。

@Override

    // Ant

    // to Ant
