is printStackTracr() method working or not???

Question

It's not showing anything about in the catch block i.e printStackTrace()... isn't it supposed to print the exception details???

here's the code:-

class A
{
public static void main (String args[])
{
try
{
for(int i=0;i<3;i++)
{
System.out.println("hello");
Thread.sleep(1000);
}
}
catch(InterruptedException ie)
{ ie.printStackTrace();}
}
}
