With C people must know __file__ and __line__, but there is no such definition in Java, sometimes debugging multithreading is very inconvenient, no way, do-it-yourself, with the following function to get the current line number.


* Get the number of lines in the exception code
* If there is no line information, return-1
public static int Getlinenumber (Exception e) {
Stacktraceelement[] Trace =e.getstacktrace ();
if (trace==null| | trace.length==0) return-1; //
return Trace[0].getlinenumber ();

Use examples:

System.out.println ("Current line:" +getlinenumber (New Exception ()));
