1. Please examine the following program. . When you execute it, use the command "java args I love cheese". Now, describe what the parameters to main, the String[] args, do.

3. Please write a program that uses the object in Question 2. This program should have two pointers to Coordinate objects, called a and b. a should represent the coordinate 3,4, and b should represent the coodinate -5,6. Calculate and print out the distance between the two points.
4. Please rewrite the program in Question 3 to ask the user to enter in the values for both coordinates.
5. Please write a program that has the user enter 10 x,y coordinates and then prints out the coordinate that is closest to 0,0. You must use an array of Coordinate objects.
6. Please examine the card object as discussed in class. Please write the game first Jack. Two players play the game first jack. They each take turns pulling cards from an infinite deck. The first player to get a Jack is the winner.
7. Please write the game Most Jacks. Each player gets 10 cards from an infinite deck. The player with the most number of jacks is the winner. If both players have the same number of jacks, then the world comes to an end and we all loose.
