public class PrintStream

extends FilterOutputStream

The top byte of 16 bit characters is discarded.

Example:

	System.out.println("Hello world!");
	System.out.print("x = ");
	System.out.println(x);
	System.out.println("y = " + y);

write(int)

Writes a byte.

write(byte[], int, int)

Writes a sub array of bytes.

  public PrintStream(OutputStream out)

Creates a new PrintStream.

Parameters:

out - the output stream

PrintStream

  public PrintStream(OutputStream out,
                     boolean autoflush)

Creates a new PrintStream, with auto flushing.

Parameters:

out - the output stream

autoflush - if true the stream automatically flushes its output when a newline character is printed.

  public void write(int b)

Writes a byte. Will block until the byte is actually written.

Parameters:

b - the byte

Throws: IOException

i/o error occurred

Overrides:

write in class FilterOutputStream

write

  public void write(byte b[],
                    int off,
                    int len)

Writes a sub array of bytes. To be efficient it should be overridden in a subclass.

Parameters:

b - the data to be written

off - the start offset in the data

len - the number of bytes that are written

Throws: IOException

i/o error occurred

Overrides:

write in class FilterOutputStream
