C# Versus Java

<b>(a)</b>
class HelloWorld {
   public static void main(String[] args) {
      System.out.println("Hello, World!");
   }
}

<b>(b)</b>
class HelloWorld {
   public static void Main(string[] args) {
      System.Console.WriteLine("Hello, World!");
   }
}

Example 1: Hello World. (a) in Java; (b) in C#.
