I assume that you know what the >> operator do.

In fact if the right hand side operator is 32, it just do nothing.

The explanation come from the modulo.

32 modulo 32 =0 so do nothing.

32 modulo 31 =31 so do 31

32 modulo 33 =1 so do 1.

So if you do

int >> 33 or int >>1 it just do the same thing.

I hope my explanation is helpfull!!!

If not,do not hesitate to contact me.

Sorry for my english

By constantly trying one ends up succeeding. Thus: the more one fails the more one has a chance to succeed.

Hi,

For shift operators, 'only the five lowest-order bits of the right-hand operand are used as the shift distance, if the left-hand operand is int'.

In case1, the 5 bits are:

In case2, the 5 bits are:

I see that your are new to this forum. Plz do a search for your question before you post. This has been discussed many times before.

System.out.println(32>>32);//case1

the result show : 32

System.out.println(32>>31);//case2

the result show : 0

For shift operators, 'only the five lowest-order bits of the right-hand operand are used as the shift distance, if the left-hand operand is int'.

In case1, the 5 bits are:

**00000**. So, the left-hand operand (32) gets shifted by 0 bits and hence the result is the same: 32.In case2, the 5 bits are:

**11111**. So, the left-hand operand (32) gets shifted by 31 bits and hence the result is: 0.I see that your are new to this forum. Plz do a search for your question before you post. This has been discussed many times before.
