## Class ServletOutputStream

- java.lang.Object
- - java.io.OutputStream
  - - javax.servlet.ServletOutputStream

- All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

      public abstract class ServletOutputStream
      extends java.io.OutputStream

  Provides an output stream for sending binary data to the client. A `ServletOutputStream` object is normally retrieved via the `ServletResponse.getOutputStream()` method.

  This is an abstract class that the servlet container implements. Subclasses of this class must implement the `java.io.OutputStream.write(int)` method.
