您可以使用Apache Commons Compress库来创建RAR4文件。以下是一个简单的示例代码:
```java
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.commons.compress.archivers.ArchiveEntry;
import org.apache.commons.compress.archivers.ArchiveOutputStream;
import org.apache.commons.compress.archivers.rar.RarArchiveEntry;
import org.apache.commons.compress.archivers.rar.RarArchiveOutputStream;
import org.apache.commons.compress.utils.IOUtils;
public class CreateRar {
public static void main(String[] args) throws IOException {
String sourceDir = "path/to/source/dir";
String destFile = "path/to/destination/file.rar";
// create output stream
FileOutputStream fos = new FileOutputStream(new File(destFile));
ArchiveOutputStream aos = new RarArchiveOutputStream(fos);
// iterate through source directory
File dir = new File(sourceDir);
for (File file : dir.listFiles()) {
// create archive entry
ArchiveEntry entry = new RarArchiveEntry(file.getName());
entry.setSize(file.length());
// add entry to archive
aos.putArchiveEntry(entry);
// write file content to archive
IOUtils.copy(file, aos);
// close current entry
aos.closeArchiveEntry();
}
// close output stream
aos.finish();
fos.close();
}
}
```
请注意,您需要在项目中添加Apache Commons Compress库的依赖关系。
