这下子,我们不用 (new Throwable()).getStackTrace ();可以调用 Thread.getCurrentThread().getStackTrace()来获得当前线程的运行栈信息。不仅如此,只要权限允许,还可以获得其它线程的运行栈信息。 /** * Returns an array of stack trace elements representing the stack dump * of this thread. This method w...
Provides programmatic access to the stack trace information printed by #printStackTrace(). (Inherited from Throwable) GetSuppressed() Returns an array containing all of the exceptions that were suppressed, typically by the try-with-resources statement, in order to deliver this exception. (Inherited...
堆栈轨迹( stack trace ):是一个方法调用过程的列表,包含了程序执行过程中方法调用的特定位置。对找出程序异常非常有用。当Java 程序因一个未捕获的异常而终止时,就会显示堆栈轨迹。// 1. 打印栈轨迹 printStackTrace,可打印 throwable 栈轨迹 catch (Exception e) { e.printStackTrace(); } // 2. 将栈轨迹...
RuntimeException() Constructs a new runtime exception withnullas its detail message. RuntimeException(IntPtr, JniHandleOwnership) A constructor used when creating managed representations of JNI objects; called by the runtime. RuntimeException(String, Throwable, Boolean, Boolean) ...

As of release 1.4, this exception has been retrofitted to conform to the general purpose exception-chaining mechanism. The "undeclared checked exception that was thrown by the invocation handler" that may be provided at construction time and accessed via the #getUndeclaredThrowable() method is now...
