24.46 java.io.OutputStream (JDK 1.0)

This abstract class is the superclass of all output streams. It defines the basic output methods that all output stream classes provide.

write() writes a single byte or an array or subarray of bytes. flush() forces any buffered output to be written. close() closes the stream and frees up any system resources associated with it. The stream may not be used once close() has been called.

See also Writer.

public abstract class OutputStream extends Object {
    // Default Constructor: public OutputStream()
    // Public Instance Methods
            public void close() throws IOException;
            public void flush() throws IOException;
            public abstract void write(int b) throws IOException;
            public void write(byte[] b) throws IOException;
            public void write(byte[] b, int off, int len) throws IOException;
