Java Programming

here is the code that implements the xor gate for my program...

    public static boolean xor(boolean... input)             //for n inputs
    {
        boolean result=input[0];                            //assigns 1st value to result
        for(int i=0; i<input.length-1;)                     //loops till length-1
        {
            result=(result&&!input[i+1])||(!result&&input[i+1]);                      //does A*B'+A'*B
            i++;
        }
        return result;
    }

the code gives the right output for 3 inputs...

now here is the code that implements the xnor gate.

    public static boolean xnor(boolean... input)             //for n inputs
    {
        boolean result=input[0];                            //assigns 1st value to result
        for(int i=0; i<input.length-1;)                     //loops till length-1
        {
            result=(result&&input[i+1])||((!result)&&(!input[i+1]));                      //does A*B+A'*B'
            i++;
        }
        return result;
 }

the output of this for a given set of input should be exactly the opposite of the output of xor gate. however, the output comes out to be the same!

i have checked my code several times and its all right. infact if i replace the above code with the following the output turns out to be fine...

    public static boolean xnor(boolean... input)             //for n inputs
    {
        return(!XOR.xor(input));
    }

any help?
