Java 9 中的 InputStream 类中添加了 transferTo() 方法。该方法已用于复制Java 中从输入流到输出流的数据。这意味着它从输入流中读取所有字节,并按照读取的顺序将字节写入输出流。
<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>
