Methods

Hide/Show inherited methods

public PrintWriter append (char c) [Overrides Writer]

Appends the specified character to this writer.

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

     out.write(c)

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

public PrintWriter append (CharSequence csq) [Overrides Writer]

Appends the specified character sequence to this writer.

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

     out.write(csq.toString())

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

public PrintWriter append (CharSequence csq, int start, int end) [Overrides Writer]

Appends a subsequence of the specified character sequence to this writer.

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.write(csq.subSequence(start, end).toString())

Returns: This writer
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

public PrintWriter printf (Locale l, String format, Object args)

A convenience method to write a formatted string to this writer using the specified format string and arguments.

A convenience method to write a formatted string to this writer using the specified format string and arguments. If automatic flushing is enabled, calls to this method will flush the output buffer.

An invocation of this method of the form out.printf(l, format, args) behaves in exactly the same way as the invocation

     out.format(l, format, args)

Returns: This writer
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
