如何使用变量为Java中的InputStream/.getResourceAsStream（variableForTextFiles）定义文件？

现在我有一个文本文件，可以读取硬编码的klebsielamicro.txt。我需要的是一个变量，

fileName

，根据不同java文件中的模板选择动态地引入不同的txtfile名称

在文件

Micro.java

下：

static void getFullMicroArray() throws IOException
{
    InputStream in = Data.class.getResourceAsStream("KlebsiellaMicro.txt");
    BufferedReader reader = new BufferedReader(new InputStreamReader(in));
    ...

JButton btnLoadMicroTemplate = new JButton("Load Template");
btnLoadMicroTemplate.addActionListener(new ActionListener() {


public void actionPerformed(ActionEvent e) {
    String fileName = null;
    String templateSelection = comboTemplateSelect.getSelectedItem().toString();
    switch(templateSelection){
        //case must match dropdown selections exactly
        case "MRSA Culture Respiratory": fileName = "MRSARespiratory.txt";
        case "Klebsiella Non-Culture Blood": fileName = "KlebsiellaMicro.txt";
        default: fileName = "MRSARespiratory.txt";
                 break;
    }
    ...

变量

fileName

位于名为

MainWindow.java的不同文件中的以下代码下：

static void getFullMicroArray() throws IOException
{
    InputStream in = Data.class.getResourceAsStream("KlebsiellaMicro.txt");
    BufferedReader reader = new BufferedReader(new InputStreamReader(in));
    ...

JButton btnLoadMicroTemplate = new JButton("Load Template");
btnLoadMicroTemplate.addActionListener(new ActionListener() {


public void actionPerformed(ActionEvent e) {
    String fileName = null;
    String templateSelection = comboTemplateSelect.getSelectedItem().toString();
    switch(templateSelection){
        //case must match dropdown selections exactly
        case "MRSA Culture Respiratory": fileName = "MRSARespiratory.txt";
        case "Klebsiella Non-Culture Blood": fileName = "KlebsiellaMicro.txt";
        default: fileName = "MRSARespiratory.txt";
                 break;
    }
    ...

如何传递此
文件名
变量以动态切换
getResourceAsStream
中的文件名？
实现此目的的一种方法是将Micro.java中的getFullMicroArray（）函数更改为接受字符串变量getFullMicroArray（String fName）。然后在MainWindow.java中case语句的末尾调用getFullMicroArray（文件名）

然后在=Data.class.getResourceAsStream（“klebsielamicro.txt”）中更改
InputStream
to
InputStream in=Data.class.getResourceAsStream（fName）
