Question
Transcribed Image Text:The image contains a segment of Java code, which includes comments and placeholders for implementing parts of the code. The code is laid out as follows:
```java
// create a loop that reads in the next int from the scanner to the intList
<YOUR CODE HERE>
// call the ReverseArray function
<YOUR CODE HERE>
System.out.print("Your output is: ");
// print the output from ReverseArray
<YOUR CODE HERE>
```
### Explanation
1. **Comments and Placeholders**:
- There are comments guiding the programmer on what needs to be done at each step.
- `<YOUR CODE HERE>` indicates where the programmer should insert their own code to perform the task described in the preceding comment.
2. **Tasks to Implement**:
- **Reading Input**: Implement a loop to read integers from an input source (scanner) and add them to a list called `intList`.
- **Calling ReverseArray**: Write code to call a function named `ReverseArray`. This likely involves passing the list as a parameter to this function.
- **Printing Output**: Once the array is reversed, print the result. The output statement starts with `System.out.print("Your output is: ");`, and the programmer needs to append the result from the `ReverseArray` function to this print statement.
This code snippet is typically part of an exercise for learning about loops, arrays, and function calls in Java programming.
![```java
import java.util.Scanner;
public class ReverseOrder {
/*
Reverse your input array
input:
int numElements: Should be greater than one
int[] intList: an array of (numElements) elements
output:
int[] : an int[] of intList in reverse
Example: ReverseArray(3, [1,2,3]) ===> [3,2,1]
*/
public static int[] ReverseArray(int numElements, int[] intList) {
<YOUR CODE HERE>
}
/*
Your first input (number of integers that follow by spaces) should be positive.
Example:
User input: 3 1 2 4
Your output: 4 2 1
Explanation: 3 is number of integers, 1 2 4 are elements of the array
*/
public static void main(String[] args) {
int numElements;
int intData;
int i;
int[] intList;
System.out.print("Enter your input: ");
// Initialize a Scanner for system input
<YOUR CODE HERE>
// Read the next integer from the Scanner and save to your numElements
<YOUR CODE HERE>
// Initialize intList with numElement size
<YOUR CODE HERE>
}
}
```
This code is part of a Java class `ReverseOrder` that includes two main parts:
1. **Method `ReverseArray`**: This method is intended to take an integer `numElements` and an array `intList`, then return a new array with the elements of `intList` in reverse order. Users are expected to complete the method where indicated by `<YOUR CODE HERE>`.
- **Input**:
- `numElements`: An integer representing the number of elements in the array, which should be greater than one.
- `intList`: An integer array containing the elements.
- **Output**:
- An integer array of `intList` in reverse order.
- **Example**: If called with `ReverseArray(3, [1,2,3])`, the method should return `[3,2,1]`.
2. **Main Method**: This method is designed to handle user input and demonstrate the reverse operation.
- **Input Format**: The user is expected to provide input](https://content.bartleby.com/qna-images/question/c7f33394-5a52-4a6c-8272-5682354fd51c/a3965291-b1fe-4642-9d03-a345f79e7997/86xhx8_processed.png)
