long mask = 0;
mask = (long) Math.pow((long)2,(long)62);
mask = mask<<1;
Thanks & Regards

as defined in java.lang.Long:
/**
* A constant holding the maximum value a <code>long</code> can
* have, 2<sup>63</sup>-1.
*/
public static final long MAX_VALUE = 0x7fffffffffffffffL;
you're trying to use a number larger than a long can contain! (don't
forget
the msb is the sign bit)
what u want is probably something like:
x = x | 0x8000000000000000L; // this is a bit-wise operator so sign
doesn't
matter
if this is what you're trying to get:
System.out.println(Long.toString(x >>> 63,2)); // prints '1'
Hope this helps!
