Consider the following schema: suppliers (sid: integer, sname: string, street: string, city: string, zip: string) parts (pid: integer, pname: string, color: string) catalog (sid: integer, pid: integer, cost: real) the primary key attributes are underlined, and the domain of each attribute is listed after the attribute name. thus, sid is the primary key for suppliers, pid is the primary key for parts, and sid and pid together form the primary key for catalog. attribute sid in catalog is a foreign key that refers to the primary key sid of suppliers and pid in catalog is a foreign key that refers to the primary key pid of parts. the catalog relation lists the prices charged for parts by suppliers.

(java)3. the answer is  (c): x[2] = 12; if x is an array with three elements, the first element has index 0. the second index has index 1. the third and final element has index 2.4. the answer is (d) for (int y : x) { system.out.println (y) ; }this is an example of syntax  of a "for-each loop."for each element in the integer array x, use y to indicate the current element to do some code with it.the other choice, (c) for (int x : y) { system.out.println (y) ; }. in a for-each loop, the variable to the right of the colon is the array variable; the one to the left is the control variable.choices (a) and (b) have invalid syntax.5. the answer is (a)  int x = {1, 2, 3, 5, 10}; you need to indicate that it is an array using []. without using [], you are trying to assign an array to an integer. you need to use int[] to indicate integer array.so choice (a) has incorrect syntax.
