Question

I have tested different elements in a char array and if they do not meet the conditions I want to remove them from the array. Is there a way to do this?

Here is my code sofar

String s;
    char[] b = inputString.toCharArray();
    b = new char[b.length];
    do
    {

        if(!(b[i]>='0')&&(b[i]<='9')&&(b[i]!='.'))
        {
            s = Character.toString(b[i]);
            if(s.equals("+"))
            {
                t = 1;
            }
            else if(s.equals("-"))
            {
                t = 2;
            }
            else if // and so on

            }
            else
            {
                t = 1029;
            }
            //want to delete element here if they fail if test
        }

This should do what you want:

ArrayList<char> charList = new ArrayList<char>(0);

for (int i= 0; i < b.length; i++) {
    if (b[i] == condition) {
        charList.Add(b[i]);
    }
}

charList.toArray();
