in java (1) Prompt the user to enter five numbers, being five people's weights. Store the numbers in an array of doubles. Output the array's numbers on one line, each number followed by one space. Ex: Enter weight 1: 236 Enter weight 2: 89.5 Enter weight 3: 142 Enter weight 4: 166.3 Enter weight 5: 93 You entered: 236.0 89.5 142.0 166.3 93.0 (2) Also output the total weight, by summing the array's elements.  (3) Also output the average of the array's elements.  (4) Also output the max array element. Ex: Enter weight 1: 236 Enter weight 2: 89.5 Enter weight 3: 142 Enter weight 4: 166.3 Enter weight 5: 93 You entered: 236.0 89.5 142.0 166.3 93.0 Total weight: 726.8 Average weight: 145.35999999999999 Max weight: 236.0

Question

in java

(1) Prompt the user to enter five numbers, being five people's weights. Store the numbers in an array of doubles. Output the array's numbers on one line, each number followed by one space.

Ex:

Enter weight 1: 236 Enter weight 2: 89.5 Enter weight 3: 142 Enter weight 4: 166.3 Enter weight 5: 93

You entered: 236.0 89.5 142.0 166.3 93.0

(2) Also output the total weight, by summing the array's elements. 

(3) Also output the average of the array's elements. 

(4) Also output the max array element.

Ex:

Enter weight 1: 236 Enter weight 2: 89.5 Enter weight 3: 142 Enter weight 4: 166.3 Enter weight 5: 93

You entered: 236.0 89.5 142.0 166.3 93.0 Total weight: 726.8 Average weight: 145.35999999999999 Max weight: 236.0

### Java Programming: People Weights

#### Lab Activity: 4.5.1 People's Weights (Java)

In this exercise, we will be working with a Java program designed to handle people's weights. The file we're working on is named `PeopleWeights.java`. Below is the initial code setup for this exercise:

```java
import java.util.Scanner;

public class PeopleWeights {
    public static void main(String[] args) {
        /* Type your code here. */

        return;
    }
}
```

#### Code Breakdown

1. **Import Statement**: 
   - `import java.util.Scanner;`
   - This line imports the Scanner class from the `java.util` package, which is used for obtaining user input.

2. **Class Declaration**:
   - `public class PeopleWeights { ... }`
   - This declares a class named `PeopleWeights`.

3. **Main Method**:
   - `public static void main(String[] args) { ... }`
   - The main method is the entry point of any Java application. This is where the program begins execution.

4. **Comments**:
   - `/* Type your code here. */`
   - A placeholder comment that indicates where you should start writing your code.

5. **Return Statement**:
   - `return;`
   - Although not necessary in the `main` method, a `return` statement can be used to exit the method. Here, it serves no purpose and can be removed or replaced with further code as needed.

#### Instructions for Completing the Activity

- Your task is to write a Java program that processes weights of various individuals, using the provided code as a starting point.
- Use the Scanner object to read weights from user input.
- Store and manipulate these weights as needed for your specific application requirements.

This activity aims to build familiarity with basic Java syntax, user input handling, and simple class/method structure.
