int p= -6969317
int r=0xff & (p>>16);

what "r" will show and how?

Have a look at the bitwise operations.

If you want to see binary representation of your int, use:

public static String toBitString(final int data){
    final StringBuilder s = new StringBuilder(32);
    for (int i = 31; i >= 0; i--) {
        s.append(data >> i & 1);
    }
    return s.toString();
}
