Class PrintStream2

Method Details

• setNewOutput

  public void setNewOutput(OutputStream out)

  Sets a new output stream for the output. This is used by the rotate trace files.

• ensureOpen

  protected void ensureOpen() throws IOException

  Check to make sure that the stream has not been closed

  Throws:

  IOException

• flush

  public void flush()

  Flush the stream. This is done by writing any buffered output bytes to the underlying output stream and then flushing that stream.

  Specified by:

  flush in interface Flushable

  Overrides:

  flush in class PrintStream

  See Also:

  • OutputStream.flush()

• close

  public void close()

  Close the stream. This is done by flushing the stream and then closing the underlying output stream.

  Specified by:

  close in interface AutoCloseable

  Specified by:

  close in interface Closeable

  Overrides:

  close in class PrintStream

  See Also:

  • OutputStream.close()

• write

  public void write(int b)

  Write the specified byte to this stream. If the byte is a newline and automatic flushing is enabled then the flush method will be invoked.

  Note that the byte is written as given; to write a character that will be translated according to the platform's default character encoding, use the print(char) or println(char) methods.

  Overrides:

  write in class PrintStream

  Parameters:

  b - The byte to be written

  See Also:

  • print(char)
  • println(char)

• write

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

  Write len bytes from the specified byte array starting at offset off to this stream. If automatic flushing is enabled then the flush method will be invoked.

  Note that the bytes will be written as given; to write characters that will be translated according to the platform's default character encoding, use the print(char) or println(char) methods.

  Overrides:

  write in class PrintStream

  Parameters:

  buf - A byte array

  off - Offset from which to start taking bytes

  len - Number of bytes to write

• print

  public void print(boolean b)

  Print a boolean value. The string produced by String.valueOf(boolean) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

  Overrides:

  print in class PrintStream

  Parameters:

  b - The boolean to be printed

• print

  public void print(char c)

  Print a character. The character is translated into one or more bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

  Overrides:

  print in class PrintStream

  Parameters:

  c - The char to be printed

• print

  public void print(int i)

  Print an integer. The string produced by String.valueOf(int) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

  Overrides:

  print in class PrintStream

  Parameters:

  i - The int to be printed

  See Also:

  • Integer.toString(int)

• print

  public void print(long l)

  Print a long integer. The string produced by String.valueOf(long) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

  Overrides:

  print in class PrintStream

  Parameters:

  l - The long to be printed

  See Also:

  • Long.toString(long)

• print

  public void print(float f)

  Print a floating-point number. The string produced by String.valueOf(float) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

  Overrides:

  print in class PrintStream

  Parameters:

  f - The float to be printed

  See Also:

  • Float.toString(float)

• print

  public void print(double d)

  Print a double-precision floating-point number. The string produced by String.valueOf(double) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

  Overrides:

  print in class PrintStream

  Parameters:

  d - The double to be printed

  See Also:

  • Double.toString(double)

• print

  public void print(char[] s)

  Print an array of characters. The characters are converted into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

  Overrides:

  print in class PrintStream

  Parameters:

  s - The array of chars to be printed

  Throws:

  NullPointerException - If s is null

• print

  public void print(String s)

  Print a string. If the argument is null then the string "null" is printed. Otherwise, the string's characters are converted into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

  Overrides:

  print in class PrintStream

  Parameters:

  s - The String to be printed

• print

  public void print(Object obj)

  Print an object. The string produced by the String.valueOf(Object) method is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

  Overrides:

  print in class PrintStream

  Parameters:

  obj - The Object to be printed

  See Also:

  • Object.toString()

• println

  public void println()

  Terminate the current line by writing the line separator string. The line separator string is defined by the system property line.separator, and is not necessarily a single newline character ('\n').

  Overrides:

  println in class PrintStream

• println

  public void println(boolean x)

  Print a boolean and then terminate the line. This method behaves as though it invokes print(boolean) and then println().

  public void println(char x)

  Print a character and then terminate the line. This method behaves as though it invokes print(char) and then println().

  Overrides:

  println in class PrintStream

  Overrides:

  println in class PrintStream

  Parameters:

  x - The int to be printed.

  Overrides:

  println in class PrintStream

  Parameters:

  x - an array of chars to print.

• println

  public void println(String x)

  Print a String and then terminate the line. This method behaves as though it invokes print(String) and then println().
