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 flush();
public void close();
public boolean checkError();
public void print(Object obj);
public void print(String s);
public void print(char[] s) throws NullPointerException;
public void print(boolean b);
public void print(char c);
public void print(int i);
public void print(long l);
public void print(float f);
public void print(double d);
public void println();
public void println(Object obj);
public void println(String s);
public void println(char[] s) throws NullPointerException;
public void println(boolean b);
public void println(char c);
public void println(int i);
public void println(long l);
public void println(float f);
public void println(double d);
}
