Answer: 12

Explanation:

 During requesting the web page with the 10 reference objects, total 12 RTTs are need for the persistent connection.

As, For handshake it require total 1 RTT and for the web page also 1 RTT required. Then, for each 10 referenced object it require total 10 RTTs.

Therefore, after adding all the RTTs = 12 RTTs required.

The persistent connection are used for reduced the network congestion and transfer the data to the end user. By using this connection we can easily find put the total reference object without any error occur during the connection.

Answer:

5 and 10

Explanation:

Given

The above code segment

Required

Determine the outputs

Analysing the code segment line by line

[This initialises c to 0]

c = 0

[The following iteration is repeated as long as c is less than 10]

while (c < 10):

[This increments c by 5]. Recall that c is initially 0. Hence, c becomes 0 + 5 = 5

c = c + 5

[This prints the value of c which is 5]

print(c)

The iteration is then repeated because the condition is still true i.e. 5 is less than 10

c = c + 5 = 5 + 5 = 10

[This prints the value of c which is 10]

print(c)

The iteration won't be repeated because the condition is now false i.e. 10 is not less than 10.

Hence, the output is 5 and 10.

Write a short program that uses a for loop to populate an array. The array can store up to 10 integers. Modify the code slightly
mr Goodwill [35]

Answer:

  1. public class num16 {
  2.    public static void main(String[] args) {
  3.        //This code is designed to create and populate an array with
  4.        //Ten Integer values
  5.        Scanner in = new Scanner(System.in);
  6.        //Create the array
  7.        int [] intArray = new int [10];
  8.        //populating the array
  9.        for(int i =0; i<=10; i++){
  10.            System.out.print("Enter the elements: ");
  11.            intArray[i]= in.nextInt();
  12.        }
  13.        //Print the Values in the array
  14.        System.out.println(Arrays.toString(intArray));
  15.    }
  16. }

Explanation:

  • The above code looks like it will run successfully and give desired output.
  • But a bug has been introduced on line 9. This will lead to an exception called ArrayIndexOutOfBoundsException.
  • The reason for this is since the array is of length 10, creating a for loop from 0-10 will amount to 11 values, and the attempt to access index 10 for the eleventh element will be illegal
  • One way to fix this bug is to change the for statement to start at 1.
