Write a Java program in jGRASP that creates a 2D integer array of 5 rows and 20 columns, fills it with increasing integer values

Alex73 [517]

Answer:

As per the question we need to make 5 rowa and 2o columns, in this we have total element 100 so range should be 0 to 99, but we are suggested to keep range 0 to 59, so i have kept the elementns in the range, but if it was a typo in the question for range you do not need to reset the k with zero.

Explanation:

//create a new class TestArray

public class TestArray {

//define main method

public static void main(String[] args) {

//declare a 2D array of given size i.e. 5 rows and 20 columns

int arr[][] = new int[5][20];

//declare an integer variable k and initialize it with zero, this will used to initialize the array from 0 to 99

int k = 0;

//for loop for rows

for (int i = 0; i < 5; i++) {

//for loop for columns

for (int j = 0; j < 20; j++) {

//initialize arr with the current value of k

arr[i][j] = k;

//once k is 59 set it zero again as we are not going beyond 59

if(k == 59)

k = 0;

//increment value of k with 1

k++;

}

}

//print the element from the array one by one

//for loop for rows

for (int i = 0; i < 5; i++) {

//for loop for columns

for (int j = 0; j < 20; j++) {

//print the current element of array and an space with it

System.out.print(arr[i][j]+" ");

}

// move the cursor to new line

System.out.println();

}

}

}

Explain benefits and disadvantages of using BNC over F-Type connectors on coaxial cables

Leokris [45]

Answer:

The benefits and disadvantages of using BNC over F-Type connectors on coaxial cables are;

The <em>benefits </em>of the BNC includes;

1) Easy connect and disconnect for a more rapid connection unlike the F-Type connector which is a screw connector

2) Reduction on stress on the termination of the coaxial cable

3) Appropriate in systems that see frequent reconfiguration unlike te F-Type connector that is permanently attached

4) Prevent unwanted disconnection ensuring image consistency by locking into place

5) Can extend to 300 ft.

The <em>disadvantages</em> of the BNC connectors are;

1) A separate power supply for the cable is required

2) Is used only for video transmission

3) Cannot be used for audio

4) The center wire is not easily visible like those of the F-Type connector which serves as a pin

5) The BNC connector is not watertight like the F-Type connectors

6) There are no provision for properly and securely attaching the cable to the camera for field work such that it can be easily disconnected while in use unlike the F-Type connectors

7) It is not as easy to manufacture like the F-Type connector and it is more expensive

8) The installation of the BNC connector on a coaxial cable is more intricate and the center cable is hidden from view after the BNC is attached thereby making it not possible to see if there is an error in installation which is unlike the F-type connector that takes less than 30 seconds to be attached to a cable

9) The F-Type connector provides more cost savings during installation than the BNC connector

Explanation:

The BNC connector is a type of bayonet connector used more frequently on CCTV systems. The benefits of the BNC includes;

The F-Type connectors are usable on SATV, CATV, and Digital TV where they are used together with RG6 or RG11 cables
