Remember that programscores[0][0] is a single int a. iii. You cannot pass a column, only pass a row a. iii. 1. a. iii. 2. a. iii. 3. Needs to have player number first then yahtzee score entirescorecard[playernumber][category] Interface: set of methods that provide common functionality, example b. i. Grect and goval are classes that provide all of the methods that are in the: how to implement interface. Public class grect implements gfillable: map interface very important d. i. Key: unique identifier which maps to some value d. ii. Value: data associated with the key d. iii. analogies d. iii. 1. Similar to phone book (string to integer) d. iii. 2. a. You get maps that you can use as interface or maps that you can implement d. iv. 2. d. iv. 3. Key and value may be different types (string and int)
