java - 如何向 OutputStream 发送内容

Question

如何向 OutputStream 发送内容？

ProcessBuilder pb = new ProcessBuilder("java", "-jar", "something.jar");
Process p = pb.start();

OutputStream out = p.getOutputStream();

//Already tried this:
InputStream in = new ByteArrayInputStream(sb.toString().getBytes());
in.transferTo(out); //But this says: This method is undefined for the type: InputStream

用 DataOutputStream 类包装它，然后您可以使用 writeUTF() 方法写入字符串对象。
