Appends the specified character to this output stream.

  Appends the specified character to this output stream.

An invocation of this method of the form out.append(c) behaves in exactly the same way as the invocation

     out.print(c) 

Returns: This output stream
Parameters:
- c - The 16-bit character to append
Since: 1.5

  Appends the specified character sequence to this output stream.

  Appends the specified character sequence to this output stream.

An invocation of this method of the form out.append(csq) behaves in exactly the same way as the invocation

     out.print(csq.toString()) 

Depending on the specification of toString for the character sequence csq, the entire sequence may not be appended. For instance, invoking then toString method of a character buffer will return a subsequence whose content depends upon the buffer's position and limit.
Returns: This output stream
Parameters:
- csq - The character sequence to append. If csq is null, then the four characters "null" are appended to this output stream.
Since: 1.5

  Appends a subsequence of the specified character sequence to this output stream.

  Appends a subsequence of the specified character sequence to this output stream.

An invocation of this method of the form out.append(csq, start, end) when csq is not null, behaves in exactly the same way as the invocation

     out.print(csq.subSequence(start, end).toString()) 

Returns: This output stream
Parameters:
- csq - The character sequence from which a subsequence will be appended. If csq is null, then characters will be appended as if csq contained the four characters "null".
- start - The index of the first character in the subsequence
- end - The index of the character following the last character in the subsequence
Throws:
- IndexOutOfBoundsException - If start or end are negative, start is greater than end, or end is greater than csq.length()
Since: 1.5

  Flushes the stream and checks its error state.

  Flushes the stream and checks its error state. The internal error state
is set to true when the underlying output stream throws an
IOException other than InterruptedIOException,
and when the setError method is invoked. If an operation
on the underlying output stream throws an
InterruptedIOException, then the PrintStream
converts the exception back into an interrupt by doing:

     Thread.currentThread().interrupt();
 

or the equivalent.
Returns: true if and only if this stream has encountered an IOException other than InterruptedIOException, or the setError method has been invoked

  Clears the internal error state of this stream.

  Clears the internal error state of this stream.

This method will cause subsequent invocations of PrintStream.checkError() to return false until another write operation fails and invokes PrintStream.setError().
Since: 1.6

  Closes the stream.

  Closes the stream. This is done by flushing the stream and then closing
the underlying output stream.
See Also: OutputStream.close(),

  Flushes the stream.

  Flushes the stream. This is done by writing any buffered output bytes to
the underlying output stream and then flushing that stream.
See Also: OutputStream.flush(),

  Writes a formatted string to this output stream using the specified format string and arguments.

  Writes a formatted string to this output stream using the specified
format string and arguments.
Returns: This output stream
Parameters:
- l - The {@linkplain java.util.Locale locale} to apply during formatting. If l is null then no localization is applied.
- format - A format string as described in Format string syntax
- args - Arguments referenced by the format specifiers in the format string. If there are more arguments than format specifiers, the extra arguments are ignored. The number of arguments is variable and may be zero. The maximum number of arguments is limited by the maximum dimension of a Java array as defined by the Java Virtual Machine Specification. The behaviour on a null argument depends on the conversion.
Throws:
- IllegalFormatException - If a format string contains an illegal syntax, a format specifier that is incompatible with the given arguments, insufficient arguments given the format string, or other illegal conditions. For specification of all possible formatting errors, see the Details section of the formatter class specification.
- NullPointerException - If the format is null
Since: 1.5

Returns: This output stream
Parameters:
- format - A format string as described in Format string syntax
- args - Arguments referenced by the format specifiers in the format string. If there are more arguments than format specifiers, the extra arguments are ignored. The number of arguments is variable and may be zero. The maximum number of arguments is limited by the maximum dimension of a Java array as defined by the Java Virtual Machine Specification. The behaviour on a null argument depends on the conversion.
