**Java Programming: Understanding Method Definitions**

This example demonstrates a basic setup of a Java class and a method that is prepared for custom implementation.

```java
public class Numbers {
public static void swapFirstLast(int[] values) {
/* Your code goes here */
}
}
```

**Code Explanation:**

- **public class Numbers**: This line declares a public class named `Numbers`. In Java, classes are the blueprint for creating objects, and this class is the outer container for methods and variables.

- **public static void swapFirstLast(int[] values)**: Here, a static method named `swapFirstLast` is defined. It takes an array of integers (`int[] values`) as its parameter. The `void` keyword indicates that this method does not return a value.

- **/* Your code goes here */**: This comment inside the method body suggests that this is where the logic for swapping the first and last elements of the array would be implemented.

At the bottom of the screen, there is a console output displaying information, likely related to a separate program run:

```

Enter scores, -1 to quit:
12 25 20 0 10 -1
You entered the following scores:
12 25 20 0 10
Process finished with exit code 0
```

**Console Output Explanation:**

- Series of numbers (`0 2 4 6 8`) and names (`Fred Amy Cindy Henry`).
- A prompt: "Enter scores, -1 to quit", followed by a series of entered scores: `12 25 20 0 10 -1`.
- Confirmation of the entered scores: `12 25 20 0 10`.
- The process finishes with an exit code of 0, indicating successful execution.

This setup provides an environment for learners to practice coding a method in Java, enhancing their understanding of class structures and console interaction.

Arrays Write three statements to print the first three elements of array runTimes. Follow each statement with a newline. Ex: If runTime = {800, 775, 790, 805, 808}, print:800 775 790 Note: These activities will test the code with different test values. This activity will perform two tests, both with a 5-element array (int runTimes[5]). See "How to Use zyBooks".Also note: If the submitted code tries to access an invalid array element, such as runTime[9] for a 5-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. #include <iostream>using namespace std; int main() {const int NUM_ELEMENTS = 5;int runTimes[NUM_ELEMENTS];int i; for (i = 0; i < NUM_ELEMENTS; ++i) {cin >> runTimes[i];} /* Your solution goes here */ return 0;} Please help me with this problem using c++.
(FYI: Pseudocode is required (Not any programming language) Design a pseudocode program that loads an array with the following 7 values. Add one more word (of your own choosing) for a total of 8 words. biffcomelyfezmottleperukebedraggledquisling Be sure to use lowercase, as shown above. This will make the processing easier. Ask the user to enter a word Search through this array until you find a match with the word the user entered. Once you find a match, output "Yes, that word is in the dictionary". If you get to the end of the array and do NOT find a match, output "No, that word is not in the dictionary". The program should work with any set of words in the arrays. If I were to change the words in the arrays, it should still work. If you need help, look at the search example in your textbook.

The program must then check the input numbers in the following order and way: 1f the input number is a negative one, the program should multiply that number by (5), and return the number of negative elements in the array. 2. if the input number is a positive one, the program should multiply that number by (2), and return the number of positive elements in the array. 3. if the input number is a zero, the program should return the number of zeros in the array The program code is given below with some missing code. You are required to write the missing code ONLY in order to make the program complete.

How do you keep tabs on the elements with data in an array that is only partially filled?
Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9

d) Print all the elements of the array that are greater than the previous element at smaller than the next element. The first and the last element should be excluded. int arr[] = {5,14,66,7,22,39,0,-12,23,91}
Program: Using a multidimensional array, create a triangular-shaped array. You will ask the user how many lines they want to see and then create the array, fill it, and then print it. You will fill the array with one 1 in the first row, two 2’s in the second row, etc. This should work for any integer that the user enters. (Just because I am starting on 1 does not mean row 0 was skipped.) You must: use a loop to create the array shape. You must: use nested for loops to fill the array and to print the values back to the screen. Your program should print as shown below. Example Output: How many lines would you like in your triangle? >>>9 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 6 6 6 6 6 6 7 7 7 7 7 7 7 8 8 8 8 8 8 8 8 9 9 9 9 9 9 9 9 9 If your code looks like the code below, it is not what I’m asking for.

part a- 2point) for 3 students find the average of a student by asking him how many grades do you have. The answer to this question, determine the size of the array(list of grades) and then ask the user to enter grades(the number of the grades is equal to the size of the array) then calculate the average for each student. Hence, you will calculate 3 averages. to calculate the average, use the array accumulator. Also when you get each grade validate it. validation for grade means that you check whether a grade is between 0 and 100. if the grade is negative or a grade is more than 100 then it is not valid and you have to ask the user to enter a grade again. Part b- 1 point) Find the maximum and minimum grades for each student. Part c- 1 point) Print the sorted list of the grades for each student. example: if grades user entered are: 60 78 98 23 45 then sorted list is:23 45 60 78 98 (Array not vector)
