入力ストリームを複数回読み取るにはどうすればよいですか?

<code class="java">ByteArrayOutputStream baos = new ByteArrayOutputStream();
org.apache.commons.io.IOUtils.copy(in, baos);
byte[] bytes = baos.toByteArray();

// Read from byte array repeatedly
while (needToReadAgain) {
    ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
    yourReadMethodHere(bais);
}</code>

<code class="java">// Create ByteArrayInputStream from original input stream
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);

// Read from input stream repeatedly
while (needToReadAgain) {
    bais.reset(); // Reset stream for subsequent reads
    yourReadMethodHere(bais);
}</code>
