Answer:
Check the explanation
Explanation:
// include the necessary packages
import java.io.*;
import java.util.*;
// Declare a class
public class DataReader
{
// Start the main method.
public static void main(String[] args)
{
// create the object of scanner class.
Scanner scan = new Scanner(System.in);
// Declare variables.
boolean done = false;
boolean done1 = false;
float sum = 0;
double v;
int count = 0;
// start the while loop
while (!done1)
{
// start the do while loop
do
{
// prompt the user to enter the value.
System.out.println("Value:");
// start the try block
try
{
// input number
v = scan.nextDouble();
// calculate the sum
sum = (float) (sum + v);
}
// start the catch block
catch (Exception nfe)
{
// input a character variable(\n)
String ch = scan.nextLine();
// display the statement.
System.out.println(
"Input Error. Try again.");
// count the value.
count++;
break;
}
}
// end do while loop
while (!done);
// Check whether the value of count
// greater than 2 or not.
if (count >= 2)
{
// display the statement on console.
System.out.println("Sum: " + sum);
done1 = true;
}
}
}
}
Sample Output:
Value:
12
Value:
12
Value:
ten
Input Error. Try again.
Value:
5
Value:
nine
Input Error. Try again.
Sum: 29.0
Answer:
Option B, Vanishing point
Explanation:
The complete question is
Where do the projection lines converge in a perspective sketch?
A. the ground line
B. the vanishing line
C. the eye point
D. the horizon line
Solution
A point lying on the image of a perspective drawing where the drawings ( two-dimensional perspective projections) of two parallel line meet in three dimensional space is known as Vanishing point
Answer:
a. new, running, waiting, ready, and terminated.
Explanation:
The process in a computer system can have different states and these are:
-New: When the process is created.
-Ready: When the process is waiting to be executed.
-Running: When the process is chosen to be executed.
-Waiting: When the process is expecting for something to happen.
-Terminated: When the process is not running anymore.
According to this, the answer is that the possible states of a process are: new, running, waiting, ready, and terminated.
