Code Explanation
  The provided solutions are simple and straightforward. They all consist of a class named Solution with a main method. Inside the main method, the two required lines of code are present:
  System.out.println("Hello, World."); prints "Hello, World." to the console.
  
  System.out.println("Hello, Java."); prints "Hello, Java." to the console.
  
  Both lines use the System.out.println() method to print the specified text followed by a newline character.
