java - 如何在java中使用另一个try block 中存在的文件路径

Question

有人可以告诉我如何在另一个 block 中使用一个 try block 中存在的文件路径吗？下面是我的代码:

    try
    {

        Path file = Paths.get("testing.txt");
        byte[] bytesFromFile = Files.readAllBytes(file);

        String textFromFile = new String(bytesFromFile, StandardCharsets.UTF_8);

        String s = String.format(textFromFile, "12");


        Path file1 = Files.write(file, s.getBytes(StandardCharsets.UTF_8), StandardOpenOption.CREATE);

        System.out.println(file1); --> **Contains file path and I want to use this in next try block.**
    }
    catch (Exception ex)
    {
        ex.printStackTrace();
    }

    try {
        ClassLoader loader = TestSpecification.class.getClassLoader();


                   input = loader.getSystemResources(file1); --> **It is throwing me an error.**


    } finally {
        if (input != null) {
            input.close();
        }
    }

以下解决方案可能对您有帮助:

Path file1 = null;
try {
    Path file = Paths.get("testing.txt");
    byte[] bytesFromFile = Files.readAllBytes(file);
    String textFromFile = new String(bytesFromFile, StandardCharsets.UTF_8);
    String s = String.format(textFromFile, "12");
    file1 = Files.write(file, s.getBytes(StandardCharsets.UTF_8), StandardOpenOption.CREATE);

    System.out.println(file1); --> **Contains file path and I want to use this in next try block.**
}
catch (Exception ex)
{
    ex.printStackTrace();
}

try {
    ClassLoader loader = TestSpecification.class.getClassLoader();
    input = loader.getSystemResources(file1); --> **It is throwing me an error.**

} finally {
    if (input != null) {
        input.close();
    }
}
