Java Iterate Bits in Byte Array

Question

How can i iterate bits in a byte array?

Answer 1

I know, probably not the "coolest" way to do it, but you can extract each bit with the following code.

    int n = 156;

String bin = Integer.toBinaryString(n);
System.out.println(bin);

char arr[] = bin.toCharArray();
for(int i = 0; i < arr.length; ++i) {
    System.out.println("Bit number " + (i + 1) + " = " + arr[i]);
}

10011100

Bit number 1 = 1

Bit number 2 = 0

Bit number 3 = 0

Bit number 4 = 1

Bit number 5 = 1

Bit number 6 = 1

Bit number 7 = 0

Bit number 8 = 0
