java wgt压缩包解压

你可以使用Java的ZipInputStream类来解压wgt压缩包。下面是一个示例代码：

import java.io.*;
import java.util.zip.*;

public class UnzipWgt {
    public static void main(String[] args) {
        String zipFilePath = "path/to/your/wgt/file.wgt";
        String destDir = "path/to/destination/directory";

        try {
            File destDirectory = new File(destDir);
            if (!destDirectory.exists()) {
                destDirectory.mkdir();
            }

            FileInputStream fis = new FileInputStream(zipFilePath);
            ZipInputStream zis = new ZipInputStream(fis);
            ZipEntry zipEntry = zis.getNextEntry();

            while (zipEntry != null) {
                String fileName = zipEntry.getName();
                File newFile = new File(destDir + File.separator + fileName);

                // Create all non-existent directories
                new File(newFile.getParent()).mkdirs();

                FileOutputStream fos = new FileOutputStream(newFile);
                byte[] buffer = new byte[1024];
                int length;

                while ((length = zis.read(buffer)) > 0) {
                    fos.write(buffer, 0, length);
                }

                fos.close();
                zipEntry = zis.getNextEntry();
            }

            zis.closeEntry();
            zis.close();
            fis.close();

            System.out.println("Wgt file successfully extracted.");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

请将`zipFilePath`替换为你的wgt文件的路径，将`destDir`替换为你想要解压到的目标目录的路径。运行上述代码后，它将解压wgt文件并将其内容提取到指定的目标目录中。
