The class is the superclass of all classes representing an output stream of bytes. An output stream accepts output bytes and sends them to some sink.Applications that need to define a subclass of OutputStream must always provide at least a method that writes one byte of output.

Class declaration

Following is the declaration for class:

public abstract class OutputStream
  extends Object
    implements Closeable, Flushable

Class constructors

S.N.Constructor & Description
Single Constructor.

Class methods

S.N.Method & Description
1 void close()
This method closes this output stream and releases any system resources associated with this stream.
2 void flush()
This method flushes this output stream and forces any buffered output bytes to be written out.
3 void write(byte[] b)
This method writes b.length bytes from the specified byte array to this output stream.
4 void write(byte[] b, int off, int len)
This method writes len bytes from the specified byte array starting at offset off to this output stream.
5 abstract void write(int b)
This method writes the specified byte to this output stream.
