UncheckedPrintWriter

public UncheckedPrintWriter(Writer out)

UncheckedPrintWriter

public UncheckedPrintWriter(Writer out,
                            boolean autoFlush)

Create a new PrintWriter.

参数：

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.

参数：

out - An output stream

另请参见：

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.

参数：

out - An output stream

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

参数：

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.

覆盖：

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.

覆盖：

类 PrintWriter 中的 print

参数：

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.

参数：

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.
