THE PACKAGE JAVA.IO

22.22 The Class

java.io.PrintStream

A

PrintStream

 adds functionality to another output stream namely, the ability

to print representations of various data values conveniently. Two other features are

provided as well. Unlike other output streams, a

PrintStream

 never throws an

IOException

; instead, exceptional situations merely set an internal flag that can

be tested by the

checkError

 method. Optionally, a

PrintStream

 can be created

so as to  autoflush ; this means that after an array of bytes is written, or after a

single byte equal to

 \n 

 is written, the

flush

 method is automatically invoked.

public class PrintStream extends FilterOutputStream {

public PrintStream(OutputStream out);

public PrintStream(OutputStream out, boolean autoflush);

public void write(int b);

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

throws NullPointerException, IndexOutOfBoundsException;

public void close();
