I am going through a socket program. In it, printStackTrace is called on the IOException object in the catch block.
What does printStackTrace() actually do?

catch(IOException ioe)
{
    ioe.printStackTrace();
}

I am unaware of its purpose. What is it used for?

java exception printstacktrace

It helps to trace the exception. For example you are writing some methods in your program and one of your methods causes bug. Then printstack will help you to identify which method causes the bug. Stack will help like this:

First your main method will be called and inserted to stack, then the second method will be called and inserted to the stack in LIFO order and if any error occurs somewhere inside any method then this stack will help to identify that method.
