    I got the string to work. I'm having an issue with the register now. Every time I create a new register, it saves over all the variables for the previous register. Is that a problem with the...

    Re: bit array and register problem

    Is there a way to form a string from an array? I want to concatenate all the values in order from Bit[i] to Bit[bit.length]

    Re: bit array and register problem

    I tried filling the array with this code:

    public Register(int numberOfBits)
    {
    Bit[] registerBit = new Bit[numberOfBits];
    for (i = 0; i < numberOfBits; i++)
    {

    Re: bit array and register problem

    for

    public Register(int numberOfBits)
    {
    Bit[] bit = new Bit[numberOfBits];
    }
    I'm supposed to set the array to all values of 0. I thought I did this when I did:

    public Bit()
    {

    Re: bit array and register problem

    Okay I think I fixed most of those errors. Now I have to create a Register method. What the professor wants is this:

    This method is the Register constructor. Its purpose is to construct a...

    Re: bit array and register problem

    the reset method is supposed to change the contents of the Bit object. It is supposed to change the value of the content to 0. That's why I originally though to use int object.

    Re: bit array and register problem

    My reset method is currently void. Should I change it to Bit?

    If I have a code like this

    public int reset()
    {
    return bit = 0;
    }

    then the method will return an integer. If I want it...

    Re: bit array and register problem

    okay that makes sense. So now I have this

    public static void LSR(Bit[] bit)
    {
    for (i = 0; i < bit.length; i++)
    {
    bit[i + 1] = bit[i];
    bit[0] = bit[0].reset();
    }
    }

    Re: bit array and register problem

    I hate asking stupid questions but I just don't seem to understand.

    bit[0] refers to the bit[] array but isn't the bit[] array an array of the Bit object? Doesn't that mean that the bit[0] is...
