class EBH019 {
public static void main (String args[]) {
int i1 = 0xffffffff, i2 = i1 << 1;
int i3 = i1 >> 1, i4 = i1 >>> 1;
System.out.print(Integer.toHexString(i2) + ",");
System.out.print(Integer.toHexString(i3) + ",");
System.out.print(Integer.toHexString(i4));
}}

hi Ajay,

I went through the discussion but I want to know conversion of hexadecimal to binary so that I can go further for the shift operation.

Thanks,

Mathangi.

hi,

hex binary
0 0000
1 0001
2 0010
3 0011
4 0100
5 0101
6 0110
7 0111
8 1000
9 1001
A 1010
B 1011
C 1100
D 1101
E 1110
F 1111

So by looking from the above table u canconvert a hexadecimal number to a binary equivalent.

ex:- FFF1 ==> 1111 1111 1111 0001

Hope u hve got it

[Mathangi Shankar]

Thanks I got the output
