Ever wanted to know the logic behind hello world program in java?

        
package cutnpaste; //package name 
        
public class HelloWorld 
{

    public static void main(String[] args) 
    {
        //initalization
        int age;
        String Message = "What is Your Name";
        String GiveAge = "Enter your age: ";
        String Name = "";
                
        Keyboard kbd = new Keyboard (); // creates an instance of Keyboard and names it kbd
        
        System.out.println(Message); // prints message string
        
        Name = kbd.readWord(); // reads a word from keyboard

        System.out.println(GiveAge);
 
        age = kbd.readInt(); // creates an instance of kbd and reads an int

        // Prints out the Name String
        System.out.print(Name);
      
        
        if (age>17)
        {
            System.out.println("You are leagal");
        }
        
        if (age>17) // if else statement
        {
            System.out.println("Time to vote");
        }
        else
        {
            System.out.println(" You can NOT Vote");
        }
        
        while (age < 100) //while loop from age to 99
        {
            System.out.println("Age is:"+ age);
            age = age +1; //counter
            
        }//end of loop
        
              
    }// end of main
}// end of HelloWorld Class
