The exception tells you exactly where it occurs, so where is that?

[Nitin Mundhe]

line no: 42
(candidate.java:42)

[Nitin Mundhe]

line no:42
c[i].getData();

Never do this catch(Exception e){}.
At least print the stack trace. Find the reported line in your code.
One of the variables being accessed at that line is null.
Use printlns to see what values your variables point to.

Thanks
but i don't get it.
please tell me what to do exactly.

[masijade]

line no:42
c[i].getData();

If that is the line then either c is null, or no element is stored under c[i]. You do know that declaring an array with a reference type (i.e. Object a = new Object[2]) does not create any objects, but rather gives each element the reference value "null", right? You need to explicitly create the object in each element i.e.

Object a = { new Object(), new Object() };
// or
Object a = new Object[2];
for (int i = 0; i < a.length; i++) {
  a[i] = new Object();
}

Thank you so much masijade...!
Problem is solved.
