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));
}}




output Prints: fffffffe,ffffffff,7fffffff


according to me output shud be

Prints: fffffffe,7fffffff,7fffffff



howcome i1 and i3 have the same output even though shift operator is used on i3 ?? also being positive numbers the use of >> & >>> should be the same on both the variables

Please point out where i,am going wrong !!


thanks

Unfortunately, 0xffffffff is not a positive integer. If you print i1, you will see that the value is -1.
