Stack trace is a collection of methods and objects that lists from the origin of the exception to the point where the nested call begins.

 class StackTrace{    StackTrace()    {        divideByzero();    }    int divideByzero()    {        return 100/0;    }    static void main(String[]arr)    {        StackTrace s=new StackTrace();    }}

When the above code is executed, the output you get on the screen might look like this:

 Exception in thread "main" java.lang.ArithmeticException: / by zero        at StackTrace.divideByzero(StackTrace.java:10)        at StackTrace.(StackTrace.java:6)        at StackTrace.main(StackTrace.java:14)

From the above code, you can see the line of execution of the program. It has to read from the bottom:

1. The main method is called.

2. The constructor (init) is called.

3. The method with the Exception is called.

This how an exception is propagated through the code.
