Answer:
public class Main
{
public static void main(String[] args) {
int [][] a = new int[4][5];
a[0][0] = 1;
a[0][1] = 2;
a[0][2] = 3;
a[0][3] = 4;
a[0][4] = 5;
a[1][0] = 10;
a[1][1] = 9;
a[1][2] = 8;
a[1][3] = 7;
a[1][4] = 6;
a[2][0] = 11;
a[2][1] = 12;
a[2][2] = 13;
a[2][3] = 14;
a[2][4] = 15;
a[3][0] = 20;
a[3][1] = 19;
a[3][2] = 18;
a[3][3] = 17;
a[3][4] = 16;
for (int i = 0; i < 4; i++) {
for (int j = 0; j < 5; j++){
System.out.print(a[i][j] + " ");
}
System.out.print("\n");
}
}
}
Explanation:
- Inside the main method, initialize the 2D array with their respective values at the appropriate indexes.
- Iterate over the 2D array using a nested For loop.
- The outer loop iterates over the rows, while the inner loop iterates over the columns of the 2D array respectively.
- Finally inside the nested For loop, print the value of 2D array using the i and j index.
Output:
1 2 3 4 5
10 9 8 7 6
11 12 13 14 15
20 19 18 17 16
Answer:
Pseudocode is an artificial and informal language that helps programmers develop algorithms. Pseudocode is a "text-based" detail (algorithmic) design tool. The rules of Pseudocode are reasonably straightforward. All statements showing "dependency" are to be indented. These include while, do, for, if, switch.
Answer:
You need to understand all the network typologies and the devices that we use in the Computer networks. You also use the techniques like routing, masking, firewalls, VPN, as well as the network protocol. And recently added is the PKI. And hence you need to make sure that you know all these, and you should also know ipv4 and ipv6. Rest you can consult Tanenbaum for further studies on Computer Network.

Answer:
This Print Screen key is used to take the screenshots of all that is appearing on the screen, and this can then be pasted in paint and saved in some location of the computer.
The Home key takes the cursor from the current position to the top left, or the start of the file.
Shift: There are two shift keys. And they are used to print the character in the capital. And when the caps lock is busy it can be used to print in lower case. It is also used together with arrow keys to select a part of the text.
Tab: This key moves the cursor from the current location to the location which we know as tab stops ( and the very next one).
Pg Up: The page up is being used for scrolling up, and the distance to which limit the scrolling will take place depends upon the application you are working on.
