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

Throwable.toString介绍

[英]Returns a short description of this throwable. The result is the concatenation of:

• the Class#getName() of the class of this object
• ": " (a colon and a space)
• the result of invoking this object's #getLocalizedMessagemethod
  If getLocalizedMessage returns null, then just the class name is returned.
  [中]返回此可丢弃项的简短描述。结果是以下各项的串联：
  *此对象的类的类#getName（）
  *“：”（冒号和空格）
  *调用此对象的#getLocalizedMessagemethod的结果
  如果getLocalizedMessage返回null，则只返回类名。
