The first homework is to create a new project called "MyOwnCommandLineArguments" as following: Receive the ages of the all your family members (between 3 to 6 members) as command line arguments in the format as following (name then age) Monica 12 Daniel 34 Shelley 23 Compute and display the average of the ages that were entered.in java

Sure, here's a sample code in Java that meets your requirements:

public class MyOwnCommandLineArguments {
    public static void main(String[] args) {
        // Check if command line arguments are valid
        if (args.length % 2 != 0 || args.length < 6 || args.length > 12) {
            System.out.println("Invalid command line arguments. Please enter names and ages of 3 to 6 family members.");
            return;
        }

        // Parse command line arguments and compute average age
        int sum = 0;
        int count = args.length / 2;
        for (int i = 1; i < args.length; i += 2) {
            try {
                int age = Integer.parseInt(args[i]);
                sum += age;
            } catch (NumberFormatException e) {
                System.out.println("Invalid age for " + args[i - 1] + ". Please enter a valid integer.");
                return;
            }
        }
        double average = (double) sum / count;

        // Display the average age
        System.out.println("The average age of " + count + " family members is " + average);
    }
}

To run this program, you can open a command prompt or terminal and navigate to the directory where you saved the above code. Then, you can compile and run the code using the following commands:

javac MyOwnCommandLineArguments.java
java MyOwnCommandLineArguments Monica 12 Daniel 34 Shelley 23

This will output the average age of the three family members provided in the example command line arguments. You can modify the command line arguments to include more family members if needed.
