Method Detail

checkError

public boolean checkError()

Description copied from class: PrintStream

This method checks to see if an error has occurred on this stream. Note that once an error has occurred, this method will continue to report true forever for this stream. Before checking for an error condition, this method flushes the stream.

Overrides:

checkError in class PrintStream

Returns:

true if an error has occurred, false otherwise

close

public void close()

Description copied from class: PrintStream

This method closes this stream and all underlying streams.

Specified by:

close in interface Closeable

Overrides:

close in class PrintStream

flush

public void flush()

Description copied from class: PrintStream

This method flushes any buffered bytes to the underlying stream and then flushes that stream as well.

Specified by:

flush in interface Flushable

Overrides:

flush in class PrintStream

print

Overrides:

print in class PrintStream

Parameters:

bool - The boolean value to print

print

public void print(char ch)

Description copied from class: PrintStream

Overrides:

print in class PrintStream

Parameters:

ch - The char value to be printed

print

public void print(char[] charArray)

Description copied from class: PrintStream

This method prints an array of characters to the stream. The actual value printed depends on the system default encoding.

Overrides:

print in class PrintStream

Parameters:

dnum - The double value to be printed

print

public void print(float fnum)

Description copied from class: PrintStream

This method prints a float to the stream. The value printed is determined using the String.valueOf() method.

Overrides:

print in class PrintStream

Parameters:
