### Question:
ZIPCompressionProvider implements CompressionProvider { @Override public ZIPCompressionInputStream createInputStream( InputStream in ) throws IOException { return new ZIPCompressionInputStream( in, this ); }  @Override ZIPCompressionInputStream createInputStream( InputStream in ); @Override boolean supportsInput(); @Override ZIPCompressionOutputStream createOutputStream( OutputStream out ); @Override boolean supportsOutput(); @Override String getDescription(); @Override String getName(); @Override String getDefaultExtension();  }### Answer:
@Test public void testCreateInputStream() throws IOException { ZIPCompressionProvider provider = (ZIPCompressionProvider) factory.getCompressionProviderByName( PROVIDER_NAME ); ByteArrayInputStream in = new ByteArrayInputStream( "Test".getBytes() ); ZipInputStream zis = new ZipInputStream( in ); ZIPCompressionInputStream inStream = new ZIPCompressionInputStream( in, provider ); assertNotNull( inStream ); ZIPCompressionInputStream ncis = provider.createInputStream( in ); assertNotNull( ncis ); ZIPCompressionInputStream ncis2 = provider.createInputStream( zis ); assertNotNull( ncis2 ); }
