Instances of this class are returned in an array by Throwable.getStackTrace( ) . Each instance represents one frame in the stack trace associated with an exception or error. getClassName( ) and getMethodName( ) return the name of the class (including package name) and method that contain the point of execution that the stack frame represents. If the class file contains sufficient information, getFileName( ) and getLineNumber( ) return the source file and line number associated with the frame. getFileName( ) returns null and getLineNumber( ) returns a negative value if source or line number information is not available. isNativeMethod( ) returns TRue if the named method is a native method (and therefore does not have a meaningful source file or line number).
