如何将对象的数据拉入事件处理程序

Question

我试图将一个名为pt的Item对象的String从ReadAndSearch类中创建到事件类中。我无法让程序返回数据，对象的时间字段只能为NULL。 ReadAndSearch类中对象的字段中有数据。在显示＆lt;＆lt; ==注释时发生错误。这是我的第一个Java程序，我在这里学习。我不确定我错过了什么，无法找到它搜索Java 7 API或从谷歌搜索。以下是涉及的三个课程;项目，ReadAndSearch和事件。

public class Item {
private String name;
private String time;

public String getName() {
    return this.name;
}

public String setName(String name){
    this.name = name;
    return name;
}
public String getTime() {
    return this.time;
}

public String setTime(String time){
    this.time = time;
    return time;
}

}

    public class Event implements ActionListener {          //wiring for action listener
    Item pt;                                            //Put item assignment here, I think scope is part of the problem.
    @Override
    public void actionPerformed(ActionEvent e) {
    newProductCode = parttextfield.getText();           //This is where I assign the input to a String object.
    ReadAndSearch rs = new ReadAndSearch();             //Sending keyboard input to method readIt of class ReadAndSearch
    rs.readIt(newProductCode);                          //Sending keyboard input to method readIt of class ReadAndSearch
        String t = pt.getTime();                        // <<== **This keeps pulling a NULL**
        int convertedtime = Integer.parseInt(t);        // <<== Added this line to convert String to int  **Failed
        System.out.println("If you can see this, " + convertedtime + " has been retrieved");
        timerLabel.setText(" "+ convertedtime);         //This is the first displayed element, then it is passed to TimeClass.
        TimeClass tc = new TimeClass(convertedtime);
        timer = new Timer(1000, tc);                    //tc is the actionListener the timer is waiting on.
        timer.start();
    }
}

public class ReadAndSearch {
public String line;
public String name;
public String time;
Item pt = new Item();

    public void readIt(String newProductCode){                                              //method that takes screen input.
        String findMe = newProductCode;                                                     //assign value of data passed in to the findMe variable.
    try {
        BufferedReader br = new BufferedReader(new FileReader("dataFile.csv")); // Open the file as a buffered reader.
        int linecount = 0;                                                      // Start a line count and declare a string to hold our current line.
        System.out.println("Searching for " + findMe + " in file...");          // Just to verify what I am searching for.
        while (( line = br.readLine()) != null) {                               // Loops through each line, stashing the line into line variable.
                linecount++;                                                    // Increment the count and find the index of the word.
                int indexfound = line.indexOf(findMe.toUpperCase());            // Convert input to case match what is in data file.
                if (indexfound > -1) {                                          // If greater than -1, means the word was found.
                                String[] parts = line.split(",");                           // Splitting file lines by comma
                                name = parts[0];                                            // Line split, this is the part number.
                                time = parts[1];                                            // Line split, this is the time allocated.
                                System.out.println(name +" was found, " + time + " seconds are allocated for completion");  //For verification of search only.
                }
        }
                    pt.setTime(time);
                    pt.setName(name);
        br.close();                                                             // Close the file after searching.
            }
    catch (IOException e) {
        System.out.println("IO Error Occurred: " + e.toString());
    }

    }
