未解决的编译和一系列未解决的变量错误

Question

这里的发布社区是新手，但我已经达成了我的智慧......我对GUI非常不熟悉，所以这里有：我需要能够使下面的Listener类与rnaSeq正确通信类。

public class RNA5 {
private static TreeMap<String, ArrayList<String>> filtered = new TreeMap<String, ArrayList<String>>();
private static ArrayList<String> ITEMS = new ArrayList<String>();

public static void main(String[] args) throws Exception {
    // TODO Auto-generated method stub
    infile();
    new rnaSeq();
}

public static TreeMap<String, ArrayList<String>> infile() throws IOException {
    InputStream stream = new FileInputStream("C:\\NEW.txt");
    BufferedReader infile = new BufferedReader(new InputStreamReader(stream));
    int i = 0;
    while(infile.ready()) {
        ArrayList<String> s = new ArrayList<String>(Arrays.asList(infile.readLine().split("\t")));
        if(i == 0) {
            for(int j = 0; j < s.size(); j++) {
                ITEMS.add(s.get(j));
            }
        }
        else {
            String firstColumn = s.get(0);
            s.remove(0);
            filtered.put(firstColumn, s);
        }
        i++;
    }
    infile.close();

    return filtered;
}

我觉得这是一个我不知道的愚蠢问题...如果需要更多信息，请告诉我！

编辑：更具体的错误是：（1）rnaSeq.Listener无法解析为类型（rnaSeq.Listener监听器），（2）方法的返回类型丢失（public rnaSeq（）...这是一个内部类），（3）监听器无法解析为变量（btnNewButton_1.addActionListener（监听器）及其兄弟），（4）btnNewButton无法解析或不是字段及其兄弟。基本上，我认为错误（3）和（4）根植于错误（1）和（2）。

Answer 1

1）在这一行：

rnaSeq.Listener listener;

您已经说过要使用在Listener类中 的rnaSeq类。没有这样的课程rnaSeq。将其更改为：

Listener listener;

2）这一行：

public rnaSeq() {

看起来它正试图成为rnaSeq类的构造函数。但是你只能在rnaSeq的类声明中声明rnaSeq类的构造函数，并且代码中没有这样的类声明。

其他错误可能是由这两个错误造成的。

顺便说一句，非常糟糕的样式使用rnaSeq作为Java类的名称。 Java类名应始终以大写字母开头。
