Answer 1

IntWritable value = new IntWritable(Integer.parseInt(someString))

... and deal with the possibility that parseInt may throw a NumberFormatException.

Someone asked:

How to overcome this NumberFormatException ???

The exception will occur if someString does not represent an integer.

What do you do?

You catch it and handle it of course! How you handle it (i.e. what you should code your application to do) will depending on the context. We can't advise on that.

Java exceptions and exception handling are described in the Oracle Java Tutorials - here.
