	System.out.println("Please enter couple sentences");
	String input = read.nextLine();
	int change = Integer.parseInt(input);
	StringToLongException trouble = new StringToLongException("USE LESS CHARS/ STRING!!");
	
		
			while(!input.equals(me)){
			 	System.out.println("Please enter couple sentences");
	 			 input = read.nextLine();
						if(input == me){}
