Answer:
The java program is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
Random r = new Random();
int x, y;
x = input.nextInt();
y = input.nextInt();
int[][] Array2D = new int[x][y];
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ Array2D[i][j] = r.nextInt(9) + 1; }
}
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
for(int i = 0; i < x ; i++){
for(int j = 1; j < y; j+=2){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
}
}
Explanation:
This creates a random object
Random r = new Random();
This declares x and y as integers
int x, y;
This gets input for x
x = input.nextInt();
This gets input for y
y = input.nextInt();
This declares the 2D array
int[][] Array2D = new int[x][y];
The following iteration populates the array with integers 1 to 9
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ Array2D[i][j] = r.nextInt(9) + 1; }
}
The following iteration prints all elements of the array
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
The following iteration prints all elements on the even column
for(int i = 0; i < x ; i++){
for(int j = 1; j < y; j+=2){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
Write a program that lets the user enter the total rainfall for each of 12 months into an array of doubles. The program should calculate and display the total rainfall for the year and the average monthly rainfall. Use bubble sort and sort the months with the lowest to highest rain amounts. Use the binary search and search for a specific rain amount. If the rain amount is found, display a message showing which month had that rain amount. Input Validation: Do not accept negative numbers for monthly rainfall figures.
Answer:
Program approach:-
Using the header file.Using the standard namespace I/O.Define the main function.Check whether entered the value is negative.Find the middle position of the array.Display message if value not found.Returning the value.Explanation:
Program:-
//required headers
#include <stdio.h>
#include<iostream>
using namespace std;
//main function
int main()
{ double rain[12], temp_rain[12], sum=0, avg=0, temp;
int month=0, i, j, n=12, low=0, mid=0, high=12, x, found=0;
char month_name[][12]={"January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"};
//store input values to arrays rain and temp_rain
while(month<n)
{ cout<<"Enter the total rainfall for month "<<month+1<<" :";
cin>>temp;
//check whether the entered value is negative
if(temp<0)
{ cout<<"Enter a non negative value"<<endl;
}
else
{ rain[month]=temp;
temp_rain[month]=temp;
//total sum is found out and stored to sum
sum+=temp;
month++;
}
}
//find average rainfall
avg=sum/n;
//display total and average rainfall for the year
cout<<"Total rainfall for the year: "<<sum<<endl;
cout<<"Average rainfall for the year: "<<avg<<endl;
//perform bubble sort on temp_rain array
for(i=0; i<n-1; i++)
{ for (j=0; j<n-i-1; j++)
{ if (temp_rain[j]>temp_rain[j+1])
{
temp=rain[j];
temp_rain[j]=temp_rain[j+1];
temp_rain[j+1]=temp;
}
}
}
//get search value and store it to x
cout<<"Enter the value to search for a specific rain amount: ";
cin>>x;
//perform binary search on temp_rain array
while (low<=high)
{
//find the middle position of the array
int mid=(low+high)/2;
//if a match is found, set found=1
if(x==temp_rain[mid])
{ found=1;
break;
}
//ignore right half if search item is less than the middle value of the array
else if(x<temp_rain[mid])
high=mid-1;
//ignore left half if search item is higher than the middle value of the array
else
low=mid+1;
}
//if a match is found, then display the month for the found value
if(found==1)
{
for(i=0; i<n; i++)
{ if(x==rain[i])
cout<<"Found matching rainfall for this month: "<<month_name[i];
}
}
//display message if value not found
else
cout<<"Value not found.";
return 0;
}

Reverse Word Order: Write a program that reverses the order of the words in a given sentence. This program requires reversing the order of the words wherein the first and last words are swapped, followed by swapping the second word with the second to last word, followed by swapping the third word and the third to last words, and so on.
Answer:
function reverseArray(arr) {
if (arr.length > 1) {
arr = [arr[arr.length-1], ...reverseArray(arr.slice(1, -1)), arr[0]]
}
return arr;
}
function reverseSentence(sentence) {
let words = reverseArray( sentence.split(" ") );
return words.join(" ");
}
console.log( reverseSentence("The quick brown fox jumps over the lazy dog's back") );
console.log( reverseSentence("one two three") );
console.log( reverseSentence("one two") );
console.log( reverseSentence("Single") );

Mencione como la electricidad evoluciono la vida el ser humano.
AYUDA
Answer:
La electricidad es el conjunto de fenómenos físicos relacionados con la carga eléctrica y los campos eléctricos y también con el electromagnetismo. Dado que la energía eléctrica es una fuente importante de energía en la vida cotidiana, las palabras "electricidad" y "corriente" a menudo se usan indistintamente en el habla cotidiana. Sin embargo, la electricidad también incluye otros fenómenos fácilmente reconocibles como los rayos y la electricidad estática.
La electricidad tiene muchas aplicaciones técnicas. Por lo tanto, la ingeniería eléctrica se explora y se desarrolla más en la ingeniería eléctrica. A diferencia de muchos otros fenómenos físicos, muchos de los fenómenos asociados con la electricidad pueden medirse y calcularse previamente con gran precisión.
La electricidad es un fenómeno natural. La más conocida es la ocurrencia de rayos, que es causada por una diferencia de potencial en la atmósfera. Algunos peces, como la anguila eléctrica, también son capaces de generar electricidad. Además, los sistemas nerviosos animal y humano funcionan con señales eléctricas.
Which of the following statements is NOT true regarding the Security Configuration and Analysis (SCA) tool?
a. It evaluates the current security state of computers in accordance with Microsoft security recommendations.
b. It allows an administrator to analyze a computer and compare its configuration settings with a baseline.
c. It can apply a baseline to force current computer settings to match the settings defined in the baseline.
d. It uses security templates to store the settings that make up baselines.
Answer: a. It evaluates the current security state of computers in accordance with Microsoft security recommendations
Explanation:
The Security Configuration and Analysis tool allows the configuration of local computers through the application of the settings in a security template to the local policy.
This allows an administrator to analyze a computer and compare its configuration settings with a baseline. The Security Configuration and Analysis (SCA) tool also uses security templates to store the settings that make up baselines.
Therefore, based on the options given, the correct option is A as the SCA tool doesn't evaluate the current security state of computers in accordance with Microsoft security recommendations.
Why might you use a navigation form instead of tab pages? The navigation form allows for several levels and sublevels to be collected. The navigation form allows for duplicate records of information to be collected. The navigation form requires all entries to be complete before adding to a database. The navigation form requires report headers and footers to make publication neater.

A constructor can be overloaded with more than one function which has the same name but with what two different things
i. Number of parameters
ii. Type of parameters
Explanation:When there are two or more constructors, definitely with the same name, in a given class, then the constructors are said to be overloaded. An overloaded constructor appears declared many times in a class but each time with different number of parameters and/or type of parameters.
For example, given a class Test, the following combination of constructors can exist;
i. public Test(int x){
}
ii. public Test(String m){
}
iii. public Test(int a, String b){
}
The following should be noted;
In the case of combination (i) and (ii), the constructors have the same number of parameters but different type of parameter. In other words, they both have 1 parameter but while the first one has a parameter type of int, the second has a parameter type of String.
In the case of combination (ii) and (iii), the constructors have different number of parameters and of course different type of parameters. In other words, the second constructor has 1 parameter of type String while the third constructor has 2 parameters of types int and String.
