Which of the following statements is false? a. InputStream and OutputStream are abstract classes for performing byte-based I/O.
b. Tubes are synchronized communication channels between threads. c. A filter stream provides additional functionality, such as aggregating data bytes into meaningful primitive-type units. FilterInputStream and FilterOutputStream are typically extended, so some of their filtering capabilities are provided by their concrete subclasses. d. A PrintStream performs text output. System.out and System.err are PrintStreams.
Tubes were streams among processes, that are interconnected. It is coordinated ways to communicate between threads, that's why the only option b is wrong, and the correct choice can be defined as follows:
In option a, the byte-based I/O the input and output stream abstract class is used, that's why it correct.
In option c, It is used to provide additional functionality, that's why it correct.
In option d, It is used to provide the text output.
