out

Writer out

The underlying character-output stream of this PrintWriter.

PrintWriter

PrintWriter (Writer out)

Creates a new PrintWriter, without automatic line flushing.

PrintWriter

PrintWriter (Writer out, 
                boolean autoFlush)

Creates a new PrintWriter.

PrintWriter

PrintWriter (OutputStream out)

Creates a new PrintWriter, without automatic line flushing, from an existing OutputStream. This convenience constructor creates the necessary intermediate OutputStreamWriter, which will convert characters into bytes using the default character encoding.

PrintWriter

PrintWriter (OutputStream out, 
                boolean autoFlush)

Creates a new PrintWriter from an existing OutputStream. This convenience constructor creates the necessary intermediate OutputStreamWriter, which will convert characters into bytes using the default character encoding.

PrintWriter

PrintWriter (String fileName)

Creates a new PrintWriter, without automatic line flushing, with the specified file name. This convenience constructor creates the necessary intermediate OutputStreamWriter, which will encode characters using the default charset for this instance of the Java virtual machine.

PrintWriter

PrintWriter (String fileName, 
                String csn)

Creates a new PrintWriter, without automatic line flushing, with the specified file name and charset. This convenience constructor creates the necessary intermediate OutputStreamWriter, which will encode characters using the provided charset.

PrintWriter

PrintWriter (File file)

Creates a new PrintWriter, without automatic line flushing, with the specified file. This convenience constructor creates the necessary intermediate OutputStreamWriter, which will encode characters using the default charset for this instance of the Java virtual machine.

PrintWriter

PrintWriter (File file, 
                String csn)

Creates a new PrintWriter, without automatic line flushing, with the specified file and charset. This convenience constructor creates the necessary intermediate OutputStreamWriter, which will encode characters using the provided charset.

append

PrintWriter append (char c)

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) 

append

PrintWriter append (CharSequence csq, 
                int start, 
                int end)

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()) 

append

PrintWriter append (CharSequence csq)

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.

checkError

boolean checkError ()

Flushes the stream if it's not closed and checks its error state.

close

void close ()

Closes the stream and releases any system resources associated with it. Closing a previously closed stream has no effect.

flush

void flush ()

Flushes the stream.

format

PrintWriter format (Locale l, 
                String format, 
                Object... args)

Writes 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.

format

PrintWriter format (String format, 
                Object... args)

Writes 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.

The locale always used is the one returned by Locale.getDefault(), regardless of any previous invocations of other formatting methods on this object.

print

void print (int i)

Prints an integer. The string produced by 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.

print

void print (double d)

Prints a double-precision floating-point number. The string produced by 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.

print

void print (boolean b)

Prints a boolean value. The string produced by 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.

print

void print (char c)

Prints 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.

print

void print (long l)

Prints a long integer. The string produced by 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.

print

void print (float f)

Prints a floating-point number. The string produced by 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.

print

void print (String s)

Prints 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.

print

void print (Object obj)

Prints an object. The string produced by the 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.

print

void print (char[] s)

Prints 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.

printf

PrintWriter printf (String format, 
                Object... args)

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(format, args) behaves in exactly the same way as the invocation

     out.format(format, args) 

printf

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. 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) 

println

void println (Object x)

Prints an Object and then terminates the line. This method calls at first String.valueOf(x) to get the printed object's string value, then behaves as though it invokes print(String) and then println().

println

void println (char x)

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

println

void println (boolean x)

Prints a boolean value and then terminates the line. This method behaves as though it invokes print(boolean) and then println().

println

void println (long x)

Prints a long integer and then terminates the line. This method behaves as though it invokes print(long) and then println().

println

void println ()

Terminates 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').

println

void println (int x)

Prints an integer and then terminates the line. This method behaves as though it invokes print(int) and then println().

println

void println (String x)

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

println

void println (char[] x)

Prints an array of characters and then terminates the line. This method behaves as though it invokes print(char[]) and then println().

println

void println (float x)

Prints a floating-point number and then terminates the line. This method behaves as though it invokes print(float) and then println().

println

void println (double x)

Prints a double-precision floating-point number and then terminates the line. This method behaves as though it invokes print(double) and then println().

write

void write (int c)

Writes a single character.

write

void write (char[] buf, 
                int off, 
                int len)

Writes A Portion of an array of characters.

write

void write (String s)

Writes a string. This method cannot be inherited from the Writer class because it must suppress I/O exceptions.

write

void write (String s, 
                int off, 
                int len)

Writes a portion of a string.

write

void write (char[] buf)

Writes an array of characters. This method cannot be inherited from the Writer class because it must suppress I/O exceptions.

clearError

void clearError ()

Clears the error state of this stream.

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

setError

void setError ()

Indicates that an error has occurred.

This method will cause subsequent invocations of checkError() to return true until clearError() is invoked.
