how to read bit pattern?

how to read each bit of a 32 bit integer ex 01111011001000 and convert 1 into 0?

thanks in advance

i don't understand the question... What do you mean by 'convert 1 into 0'?

if you are trying to convert it into a decimal number, each position represents a power of 2, just like decimal each position is a power of 10.

So the rightmost digit is 2^0, the next is 2^1, the next is 2^2, etc. you just add up the values where there is a 1. so if i had a four digit binary like "0111", i'd add up 2^0 + 2^1 + 2^2, which totals 7.

Does that help?

If you want to convert all ones into zeros, why not just assign the value 0? That's your number with all ones converted to zeros ;)

If you also want to convert zeros into ones, there's an operator for that: ~. It returns the number with all bits flipped.

Depending upon requirement i want to create method which read each bit and convert 1 into 0 and print that 32 bit pattern with 1 converted into 0.

Sounds like a use for Rob's suggestion with the ~ operator and a method in the Integer class which creates a String with the binary pattern in.

if you convert all the 1s to 0s, and leave the 0s alone, you're left with nothing but all 0's.
