How do I get the exception stack trace in Java? I can use Thread.currentThread().getStackTrace().but get error linenumber
Correctly:
java.lang.ArithmeticException: / by zero at me.edagarli.Main.main(Main.java:32) Wrongly:
java.lang.ArithmeticException: / by zero java.lang.Thread.getStackTrace(Thread.java:1589) me.edagarli.Main.main(Main.java:54) 
public String getFullErrorDescription(Exception exceptionObj ) { String textmsg = ""; if (exceptionObj != null) { StackTraceElement[] ste = exceptionObj.getStackTrace(); textmsg += "\nIn File : " + ste[index].getClassName() + " "; textmsg += "\nIn Method : " + ste[index].getMethodName() + "() "; textmsg += "\nAt Line :" + ste[index].getLineNumber() + " "; } System.err.println(textmsg); return textmsg; } If you need to have stacktrace messages into String instance you can use:
public String getStackTraceAsString(Exception ex){ StackTraceElement[] elements = ex.getStackTrace(); String stacktraceMessage = ""; for(StackTraceElement element : elements){ stacktraceMessage += "\nIn File : " + element.getClassName() + " "; stacktraceMessage += "\nIn Method : " + element.getMethodName() + " "; stacktraceMessage += "\nAt Line :" + element.getLineNumber() + " "; } return stacktraceMessage; } If you need only print stacktrace you can use printStackTrace method:
try{ int a = 100 / 0; }catch (Exception ex){ ex.printStackTrace(); }
