Method Detail

flush

public void flush()

Flush the stream. This is done by writing any buffered output bytes to the underlying output stream and then flushing that stream.

Specified by:

flush in interface OutputStreaming

Specified by:

flush in interface Flushable

Overrides:

flush in class PrintStream

See Also:

OutputStream.flush()

close

public void close()

Close the stream. This is done by flushing the stream and then closing the underlying output stream.

Specified by:

close in interface OutputStreaming

Specified by:

close in interface Closeable

Overrides:

close in class PrintStream

See Also:

OutputStream.close()

checkError

public boolean checkError()

Flush the stream and check its error state. The internal error state is set to true when the underlying output stream throws an IOException other than InterruptedIOException, and when the setError method is invoked. If an operation on the underlying output stream throws an InterruptedIOException, then the PrintStream converts the exception back into an interrupt by doing:

     Thread.currentThread().interrupt();
 

or the equivalent.

Overrides:

checkError in class PrintStream

Returns:

True if and only if this stream has encountered an IOException other than InterruptedIOException, or the setError method has been invoked

setError

protected void setError()

Set the error state of the stream to true.

Overrides:

setError in class PrintStream

Since:

JDK1.1

write

public void write(int b)

Write the specified byte to this stream. If the byte is a newline and automatic flushing is enabled then the flush method will be invoked.

Note that the byte is written as given; to write a character that will be translated according to the platform's default character encoding, use the print(char) or println(char) methods.

Specified by:

write in interface OutputStreaming

Overrides:

write in class PrintStream

Parameters:

b - The byte to be written

See Also:

print(char), println(char)

write

public void write(byte[] ab,
                  int of,
                  int cb)

Write len bytes from the specified byte array starting at offset off to this stream. If automatic flushing is enabled then the flush method will be invoked.

Note that the bytes will be written as given; to write characters that will be translated according to the platform's default character encoding, use the print(char) or println(char) methods.

Specified by:

write in interface OutputStreaming

Overrides:

write in class PrintStream

Parameters:

ab - A byte array

of - Offset from which to start taking bytes

cb - Number of bytes to write

print

public void print(boolean f)

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 PrintStream

Parameters:

f - The boolean to be printed

print

public void print(char ch)

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 PrintStream

Parameters:

ch - 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 PrintStream

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 PrintStream

Parameters:

l - The long to be printed

See Also:

Long.toString(long)

print

public void print(float fl)

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 PrintStream

Parameters:

fl - The float to be printed

See Also:

Float.toString(float)

print

public void print(double dfl)

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 PrintStream

Parameters:

dfl - The double to be printed

See Also:

Double.toString(double)

print

public void print(char[] ach)

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 PrintStream

Parameters:

ach - 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 PrintStream

Parameters:

s - The String to be printed

print

public void print(Object o)

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.

Overrides:

print in class PrintStream

Parameters:

o - The Object to be printed

See Also:

Object.toString()
