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.

Answer:

The answer is "Option b".

Explanation:

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.

Algorithm and flowchart to find the perimeter and area of square​
kupik [55]

Answer:

I can give you the perimeter "algorithm" but not the flowchart.

Here you go:

p = w * 4

p = perimiter,

w = width/height

4 = the amount of sides needed.

perimeter = width * 4

to include both width and height, we would instead use:

perimeter = 2(width+height)

This also works with rectangles ^

--------------------------------------------------------------------------

To find an area, it is just width * height. This is also compatible with rectangles.

The area of a square is stored in a double variable named area. Write an expression whose value is length of the diagonal of the
melisa1 [442]

Answer:

sqrt(area)

Explanation:

  • Here sqrt is a short form of square root.
  • area is a variable name having he area of square.
  • When the function is called, it will give the square root of the value stored in variable area.

As we have to find the length of the diagonal, we must knew that as all sides of the square are same in length so are the diagonals. This means that each of the four sides of the square and it diagonals are equal in length.

So a square has: length=breadth=diagonal

As  Area= length*breadth

√area = length           (as length = diagonal length)

So     √area = diagonal length

What is the first stage of perception
Zigmanuir [339]

If we do not attend to stimuli, then we cannot perceive stimuli; thus attention is a critical factor in the process of perception. Receiving and attending to stimuli is the first stage in perception. Once we collect stimulus information from the senses, we have to try to make sense of it. This is called organization.

Write a loop that reads c-strings from standard input where the c-string is either "land", "air", or "water". The loop terminate
Anvisha [2.4K]

Answer:

I am writing a C++ code.        

#include <iostream> // for input output functions

using namespace std; // identifies objects like cin cout

int main() { //start of main() function body

string c_string; // stores the string entered by user from land water or air

int land=0; // contains the number of times land string is read in

int air=0; //contains the number of times air string is read in

int water = 0; //contains the number of times water string is read in

cin>>c_string; //reads the string entered by user from air water or land

/*while loop continues to execute until user enters xxxxx or maximum length of a string exceeds 8 */

while(c_string!= "xxxxx" && c_string.length()<=8) {

if(c_string=="land"){ // if string entered by user is land

land = land + 1;} //counts and increments each occurrence of land string by 1

else if(c_string=="air"){// if string entered by user is air

air = air + 1;}// counts and increments each occurrence of string air by 1

else if(c_string=="water"){// if string entered by user is water

water = water + 1;}//counts and increments each occurrence of air by 1

cin>>c_string;}

/* keeps reading the string entered by user from land air or water, until the loop breaks after the user enters xxxxx or user enters a string whose length is greater than 8 */

//prints the number of times land, air and water are read in

cout << "land:"<<land;

cout << endl<<"air:"<<air;

cout << endl<< "water:"<<water; }                      

                                                                                     

Explanation:

Everything is well explained in the comments above.

The program prompts the user to input strings. These strings are either land air or water. The while loop continues to read the input strings until user enters xxxxx or the string entered by user exceeds the length 8. Both these terminating conditions are added in the while loop. After the loop terminates, the number of times land, air and water strings are read is displayed on the output screen. Any other string entered by user other than these 3 is ignored. The program along with the output is attached.
