  5. 	//----------How the program should work-------------------//
  6. 	//Create a dice program which lets the user choose between h/l (High/Low)
  7. 	//The dice is then rolled and depending on which number it lands on there are different
  8. 	//actions.
  9. 	// l = 1-3, h = 4-6
  10. 	//The user should start with a bank value of a 1000 marks.
  11. 	//For each win the amount of the bet should be doubled.
  12. 	//After a win/loss the user should be prompted again, asking if they want to play again.
  13.  
  14. 	//----------How to create the program --------------------//
  15. 	//Create a boolean variable for the loop so the user can be prompted after one run.
  16. 	//Create one integer for the bank value and one for the dice.
  17. 	//Create a char and set make it so the Scanner takes in values for either 'h' or 'l'
  18. 	//If the user gives any value other than the ones above prompt them to do it over again.
  19. 	//Create a random method which random's out the dice number.
  20. 	//Create an switch/case for the different outcomes on the dice number.
  21.  
  22. 	//------Problems encountered----//
  23. 	//Everything works until the last step, whenever you win/lose
  24. 	//the bankValue doesn't change.
