Throwable 和 Exception 是 Java 中的两种异常类型。Throwable 是 Java 中所有异常和错误的父类,而 Exception 则是可检查异常的父类。可检查异常是指程序员可以通过捕获或声明来处理的异常,而不可检查异常则是程序员无法处理的异常。Error 类是 Throwable 的子类,表示严重问题,如虚拟机错误。

throwable和exception的区别
"Throwable"和"Exception"是Java异常处理机制中的两个不同的概念。在Java中,所有异常都是以Throwable类为基类的,它有两个子类:Error和Exception。Error通常是指系统或虚拟机错误,如OutOfMemoryError等,不建议处理。而Exception则是指程序运行过程中出现的错误,可通过编写代码来处理或捕获。因此,Throwable的子类有两种情况:Error和Exception。
Throwable targetException = var6.getTargetException()
This code retrieves the target exception that was thrown by the specified invocation target.
In Java, when a method is invoked using reflection, the invoked method may throw an exception. Instead of throwing the exception directly, the method wraps the exception in a InvocationTargetException and throws it.
To retrieve the original exception, you can use the getTargetException() method of the InvocationTargetException. This code assigns the target exception to a Throwable variable named targetException.
