请告诉我为什么如果我试图获得数组的长度,我的小应用程序总是会出错.

请在下面找到我的代码:

1. String Parser

    package dl.data.background;

    import java.util.ArrayList;
        public class StringParser {

        public StringParser()
        {

        }

        public ArrayList<Object> Parse (String input) {
            ArrayList<Object> output = new ArrayList <Object>();

            int pointer = 0;
            String data = "";

            while (pointer <= input.length()-1)
            {
                if(input.charAt(pointer) == '#'){
                    output.add(data);
                    data = "";
                    pointer++;
                }
                if(pointer < input.length())
                {
                    data += input.charAt(pointer);
                }
                pointer++;
            }
            return output;
        }
    } 

2.下载数据

    package dl.data.background;

    import java.io.BufferedReader;
    import java.io.InputStream;
    import java.io.InputStreamReader;
    import java.util.ArrayList;

    import org.apache.http.HttpResponse;
    import org.apache.http.client.methods.HttpGet; …
