java.lang.System.lineSeparator()方法的使用及代码示例
本文整理了Java中java.lang.System.lineSeparator()方法的一些代码示例，展示了System.lineSeparator()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。System.lineSeparator()方法的具体详情如下：
包路径：java.lang.System
类名称：System
方法名：lineSeparator
System.lineSeparator介绍
[英]Returns the system's line separator. On Android, this is "\n". The value comes from the value of the line.separator system property when the VM starts. Later changes to the property will not affect the value returned by this method.
[中]返回系统的行分隔符。在Android上，这是“\n”。该值来自该行的值。VM启动时的分隔符系统属性。以后对属性的更改不会影响此方法返回的值。
