### RarArchive(String path) {#RarArchive-java.lang.String-}
```
public RarArchive(String path)
```


Initialiserar en ny instans av klassen [RarArchive](../../com.aspose.zip/rararchive) och skapar en postlista som kan extraheras från arkivet.

Följande exempel extraherar ett arkiv och dekomprimerar sedan den första posten till en `MemoryStream`.

```

``````

ByteArrayOutputStream extracted = new ByteArrayOutputStream();
try (RarArchive archive = new RarArchive("data.rar")) {
try (InputStream decompressed = archive.getEntries().get(0).open()) {
byte[] b = new byte[8192];
int bytesRead;
while (0 < (bytesRead = decompressed.read(b, 0, b.length)))
extracted.write(b, 0, bytesRead);
} catch (IOException ex) {
}
}
 
```

This constructor does not decompress any entry. See [RarArchiveEntry.open()](../../com.aspose.zip/rararchiveentry\#open--) method for decompressing.

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| path | java.lang.String | The fully qualified or the relative path to the archive file. |

### RarArchive(String path, RarArchiveLoadOptions loadOptions) {#RarArchive-java.lang.String-com.aspose.zip.RarArchiveLoadOptions-}
```
public RarArchive(String path, RarArchiveLoadOptions loadOptions)
```


Initializes a new instance of the [RarArchive](../../com.aspose.zip/rararchive) class and composes an entry list can be extracted from the archive.

The following example extracts an archive, then decompress first entry to a `MemoryStream`.

```

``````

     ByteArrayOutputStream extracted = new ByteArrayOutputStream();
     try (RarArchive archive = new RarArchive("data.rar")) {
         try (InputStream decompressed = archive.getEntries().get(0).open()) {
             byte[] b = new byte[8192];
             int bytesRead;
             while (0 < (bytesRead = decompressed.read(b, 0, b.length)))
                 extracted.write(b, 0, bytesRead);
         } catch (IOException ex) {
         }
     }
 
```

Denna konstruktor dekomprimerar inte någon post. Se metoden [RarArchiveEntry.open()](../../com.aspose.zip/rararchiveentry\#open--) för dekomprimering.
