- Constructor Detail
  - PrintWriter2
```
public PrintWriter2(java.io.Writer out)
```
    Create a new PrintWriter, without automatic line flushing.
    
    Parameters:
    out - A character-output stream
  - PrintWriter2
```
public PrintWriter2(java.io.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
  - PrintWriter2
```
public PrintWriter2(java.io.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)
  - PrintWriter2
```
public PrintWriter2(java.io.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
  - setLineSeparator
```
public void setLineSeparator(java.lang.String separator)
```
    Sets the line separator for the writer.
  - getLineSeparator
```
public java.lang.String getLineSeparator()
```
  - flush
```
public void flush()
```
    Flush the stream.
    
    Specified by:
    
    flush in interface java.io.Flushable
    
    Specified by:
    
    flush in class java.io.Writer
  - close
```
public void close()
```
    Close the stream.
    
    Specified by:
    
    close in interface java.io.Closeable
    
    Specified by:
    
    close in interface java.lang.AutoCloseable
    
    Specified by:
    
    close in class java.io.Writer
  - checkError
```
public boolean checkError()
```
    Flush the stream and check its error state. Errors are cumulative; once the stream encounters an error, this routine will return true on all successive calls.
    
    Returns:
    True if the print stream has encountered an error, either on the underlying output stream or during a format conversion.
  - setError
```
protected void setError()
```
    Indicate that an error has occurred.

    write in class java.io.Writer
  - 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.
    
    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.
    
    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.

```
public void print(java.lang.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.
    
    Parameters:
    s - The String to be printed

    obj - The Object to be printed
    See Also:
    Object.toString()
  - println
```
public void println()
```

```
public void println(boolean x)
```
    Print a boolean value and then terminate the line. This method behaves as though it invokes print(boolean) and then println().

```
    Print a long integer and then terminate the line. This method behaves as though it invokes print(long) and then println().
  - println
```
public void println(float x)
```
    Print a floating-point number and then terminate the line. This method behaves as though it invokes print(float) and then println().
  - println
```
public void println(double x)
```
    Print a double-precision floating-point number and then terminate the line. This method behaves as though it invokes print(double) and then println().
  - println
```
public void println(char[] x)
```
    Print an array of characters and then terminate the line. This method behaves as though it invokes print(char[]) and then println().
  - println
