用Java从ZIP压缩包中提取UTF-16编码的文件

在代码的最后一部分，我打印了读者给我的内容。但这只是假的，我哪里错了？

public static void read_impl(File file, String targetFile) {
    // Create zipfile input stream
    FileInputStream stream = new FileInputStream(file);
    ZipInputStream zipFile = new ZipInputStream(new BufferedInputStream(stream));

    // Im looking for a specific file/entry
    while (!zipFile.getNextEntry().getName().equals(targetFile)) {
        zipFile.getNextEntry();
    }

    // Next step in api requires a reader
    // The target file is a UTF-16 encoded text file
    InputStreamReader reader = new InputStreamReader(zipFile, Charset.forName("UTF-16"));

    // I cant make sense of what this print
    char buf[] = new char[1];
    while (reader.read(buf, 0, 1) != -1) {
        System.out.print(buf);
    }
}

In the last section of the code I print what the Reader gives me. But its just bogus, where did I go wrong?

public static void read_impl(File file, String targetFile) {
    // Create zipfile input stream
    FileInputStream stream = new FileInputStream(file);
    ZipInputStream zipFile = new ZipInputStream(new BufferedInputStream(stream));

    // Im looking for a specific file/entry
    while (!zipFile.getNextEntry().getName().equals(targetFile)) {
        zipFile.getNextEntry();
    }

    // Next step in api requires a reader
    // The target file is a UTF-16 encoded text file
    InputStreamReader reader = new InputStreamReader(zipFile, Charset.forName("UTF-16"));

    // I cant make sense of what this print
    char buf[] = new char[1];
    while (reader.read(buf, 0, 1) != -1) {
        System.out.print(buf);
    }
}

我猜你出错的地方是相信该文件是 UTF-16 编码的。

如果不解码它们，您能显示一些初始字节值吗？

您使用 char 数组有点毫无意义，尽管乍一看它应该可以工作。请尝试以下操作：

int c;
while ((c = reader.read()) != -1) {
    System.out.print((char)c);
}

如果这也不起作用，那么可能您得到了错误的文件，或者该文件不包含您认为的内容，或者控制台无法显示它包含的字符。

Your use of a char array is a bit pointless, though at first glance it should work. Try this instead:

int c;
while ((c = reader.read()) != -1) {
    System.out.print((char)c);
}

If that does not work either, then perhaps you got the wrong file, or the file does not contain what you think it does, or the console can't display the characters it contains.
