/*
//This is a second class to Java Project 
 1) it will change modes
 2) Hold the arrayList of strings 
 3) If mode = Queue it will delete first item in array_List and add item to the back
 	Queue will delete from Front, move all elemnts forward and add new elements in the 
 		back 
 			Think of a line at a fast food retruant were the first person orders, grabs 
 			their food and new people join the line from the back and move forward. 
 //---------------------------------------------------------------------------------------
 3) If mode = Stack it will delete Last item in array_List and add item to the top   
 	Stack will delete from top of a stack and delete from the top  
 			Think of papaers stacked in a pile, and you grab from the top of the pile		
 	
 4) make the Clear button function work properly  
 5) lastly use a ToString method to put all arrayList elements into a string to show
 to a user
