olganol [36]

Answer:

The program displays 5 4 3 2 1 and then raises an Array Index Out Of Bounds Exception.

Explanation:

A sample of code output is attached.

The code snippet contain xMethod that takes an array and array length as argument.

In the given snippet, the array {1, 2, 3, 4, 5} and length (5) is passed as argument to the method.

First the method display the element of the array in reverse order

System.out.print(" " + x[length - 1]);

and then the method call itself again. This displays

5 from x[4]

4 from x[3]

3 from x[2]

2 from x[1]

1 from x[0]

but after displaying 1, when it tries to call the method again, an array index out of bound exception is thrown because it will try accessing an element from the array when it is already exhausted.

nadya68 [22]

Answer:

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

Scanner ob = new Scanner(System.in);

System.out.println("How many numbers? ");

int n = ob.nextInt();

int[] arr = new int[n];

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

System.out.print("Enter the number: ");

arr[i] = ob.nextInt();

}

System.out.println(indexOfLargestElement(arr));

}

public static int indexOfLargestElement(int[] arr) {

int max = arr[0];

int maxIndex = 0;

for (int i=0; i<arr.length; i++) {

if (arr[i] >= max) {

max = arr[i];

maxIndex = i;

}

return maxIndex;

}

Explanation:

Create a method called indexOfLargestElement that takes one parameter, an array

Initialize the max and maxIndex

Create a for loop iterates throgh the array

Check each element and find the maximum and its index

Return the index

Inside the main:

Ask the user to enter how many numbers they want to put in array

Get the numbers using a for loop and put them inside the array

Call the indexOfLargestElement method to find the index of the largest element in the array

while(true)

{

input = Console.ReadLine();

if(input.Equals(""quit""))

break;

Reverse_String(input);

}

return;

}

static void Reverse_String(string input_text)

{

char[] text = input_text.ToCharArray();

Array.Reverse(text);

Console.WriteLine(text);

}

Explanation:

In the above program a separate function is written to reverse the string.

This method takes the string as an argument and place it in a array and then use the built-in function reverse and print the reversed string in the console.

In the main(), the input is obtained from the console and it is passed to the reversestring().

When you pass an array as an argument to a function, the function can modify the contents of the array?

taurus [48]

In most languages. Primitive data types ( char, int, float, bool, maybe string ) are usually passed by value, but compound data types are passed by reference, so you're not working on a copy but on the original.

Do you need a contractor to install nest thermostat

Natalka [10]

Answer:

Sometimes yes, sometimes you can do it yourself

Explanation:

Installing a Nest thermostat can be done yourself without an electrician in most cases. Nest thermostats are designed to work in homes without a common (“C”) wire.
