1. Write a program that inputs an array of numbers from the command line, and averages them. The program should work for any decimal numbers that can be stored with the datatype double , as shown below. Here is some sample output: > java -classpath .:/run_dir/junit-4.12.jar:target/dependency/* Main usage: java Main 5 4 2 8 To average the numbers 5, 4, 2 and 8 > java Main 1.5 2 2.5 43.222 3 Here is your array of numbers: 1.5, 2.0, 2.5, 43.222, 3.0 and their average is: 10.4444 > java Main 1 2 3 4 Here is your array of numbers: 1.0, 2.0, 3.0, 4.0 and their average is: 2.5

This assignment will help you to get started with NetBeans and using Java compiler:   To begin, put a block comment at the beginning of your Java file (and every Java source file in the future) with the assignment number, assignment title, program author [your name], and the date it's due. Next, similar to the programs presented in the first chapter of the textbook, use System.out object to display the following information: Your first name The name of the operating system you are using The name of your project (or simply the folder name if not using the IDE) The name of the class that contains the main() method in your source file. Note: Your program should print each of the above items on a separate output line. "The name of the class that contains the main() method in your source file.public class MyClass {    public static void main(String[]) {        System.out.println( "Hi" );    }}

java  a. You want to create a Java main class. You create the source code file, declare the package, and write the class header. Now you must create the main method that starts the program. Write the entire method header, including the opening brace for the method. b. Assume that price is an integer variable whose value is the price (in US currency) in cents of an item. Write a statement that calculates the whole dollars in the amount and saves it in a new integer variable named dollars. Note: The Java style guide states that one space is used on either side of binary operators.

In a Java application, we know that we must have a Main method to run the program.  What tells the Main method to run and what would happen if you did not include the Main method in your Java application?
