在Java 9中，transferTo()方法的重要性是什么？

<strong>public long transferTo(OutputStream out) throws IOException</strong>

import java.util.Arrays;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;

public class TransferToMethodTest {
   public void testTransferTo() throws IOException {
      byte[] inBytes = "tutorialspoint".<strong>getBytes()</strong>;
      <strong>ByteArrayInputStream </strong>bis = new ByteArrayInputStream(inBytes);
      <strong>ByteArrayOutputStream </strong>bos = new ByteArrayOutputStream();
      try {
         bis.<strong>transferTo</strong>(bos);
         byte[] outBytes = bos.<strong>toByteArray</strong>();
         System.out.println(<strong>Arrays.equals(</strong>inBytes, outBytes));
      } finally {
         try {
            bis.close();
         } catch(IOException e) {
            e.printStackTrace();
         }
         try {
            bos.close();
         } catch(IOException e) {
              e.printStackTrace();
         }
      }
   }
   public static void main(String args[]) throws Exception {
      TransferToMethodTest test = new TransferToMethodTest();
      test.testTransferTo();
   }
}

<strong>true</strong>
