Constructor Detail

UncheckedPrintWriter

public UncheckedPrintWriter(Writer out)

UncheckedPrintWriter

public UncheckedPrintWriter(Writer out,
                            boolean autoFlush)

Create a new PrintWriter.

Parameters:

out - A character-output stream

autoFlush - A boolean; if true, the println() methods will flush the output buffer

UncheckedPrintWriter

public UncheckedPrintWriter(OutputStream out)

Create 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.

Parameters:

out - An output stream

See Also:

OutputStreamWriter.OutputStreamWriter(java.io.OutputStream)

UncheckedPrintWriter

public UncheckedPrintWriter(OutputStream out,
                            boolean autoFlush)

Create 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.

Parameters:

out - An output stream

autoFlush - A boolean; if true, the println() methods will flush the output buffer

See Also:

OutputStreamWriter.OutputStreamWriter(java.io.OutputStream)

Method Detail

flush

public void flush()

Flush the stream.

Specified by:

flush in interface Flushable

Overrides:

flush in class PrintWriter

close

public void close()

Close the stream.

Specified by:

close in interface Closeable

Overrides:

close in class PrintWriter

write

public void write(int c)

Write a single character.

Overrides:

write in class PrintWriter

Parameters:

c - int specifying a character to be written.

write

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

Write a portion of an array of characters.

Overrides:

write in class PrintWriter

Parameters:

buf - Array of characters

off - Offset from which to start writing characters

len - Number of characters to write

write

public void write(char[] buf)

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

Overrides:

write in class PrintWriter

Parameters:

buf - Array of characters to be written

write

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

Write a portion of a string.

Overrides:

write in class PrintWriter

Parameters:

s - A String

off - Offset from which to start writing characters

len - Number of characters to write

write

public void write(String s)

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

Overrides:

write in class PrintWriter

Parameters:

s - String to be written

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 PrintWriter

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 PrintWriter

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 PrintWriter

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 PrintWriter

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 PrintWriter

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 PrintWriter

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 PrintWriter

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 PrintWriter

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.

Parameters:

obj - The Object to be printed
