POIs it acceptable to repeat variables, when listing variables for certain objects?

copied!<p>Here's an example case:</p> <pre> public list getPizzaIngredients(pizzaName) { if pizzaName = HAWAIIAN return [ CHEESE, TOMATO SAUCE, PINEAPPLE, HAM]; if pizzaName = ITALIAN return [ CHEESE, TOMATO SAUCE, PEPPERONI, OLIVES]; if pizzaName = MEATLOVERS return [ CHEESE, TOMATO SAUCE, PEPPERONI, BACON, SAUSAGE, OLIVES]; return null; } </pre> <p>Here we are repeating ingredients in each list. An alternative way to do is:</p> <pre> public list getPizzaIngrediants(pizzaName) { ing = []; ing.add(CHEESE) ing.add(TOMATO SAUCE); if pizzaName in (HAWAIIAN) ing.add(PINEAPPLE); if pizzaName in (HAWAIIAN) ing.add(HAM); if pizzaName in (ITALIAN, MEATLOVERS) ing.add(PEPPERONI); if pizzaName in (ITALIAN, MEATLOVERS) ing.add(OLIVES); if pizzaName in (MEATLOVERS) ing.add(BACON); if pizzaName in (MEATLOVERS) ing.add(SAUSAGE); return ing; </pre> <p>or we could make it more concise:</p> <pre> public list getPizzaIngrediants(pizzaName) { ing = []; ing.add(CHEESE,TOMATO SAUCE) if pizzaName in (HAWAIIAN) ing.add(PINEAPPLE, HAM); if pizzaName in (ITALIAN, MEATLOVERS) ing.add(PEPPERONI, OLIVES); if pizzaName in (MEATLOVERS) ing.add(BACON, SAUSAGE); return ing; </pre> <p>Now personally - although the first example is wordier and involves repeating the variables, it's far more readable and easier to modify than the other two solutions.</p> <p>Is there a convention around this kind of programming style/issue?</p>
