		Scanner keyBoard = new Scanner(System.in);


		// Allows the user to input a TypeAccount enum
		System.out.print("Input a TypeAccount enum 1,2,3: ");
		int typeAccountEnum = keyBoard.nextInt();
		// Displays the value that the enums represents
		if (TypeOfAccount.TypeOne == TypeOfAccount.fromInteger(typeAccountEnum)) {
			System.out.println("Saving Account");
		} else if (TypeOfAccount.TypeTwo == TypeOfAccount.fromInteger(typeAccountEnum)) {
			System.out.println("Salary Account");
		} else if (TypeOfAccount.TypeThree == TypeOfAccount.fromInteger(typeAccountEnum)) {
			System.out.println("Checking Account");
		}else {
			System.out.println("WRONG selection");
