A simple hash algorithm to map a set of integers into array locations is the _______________  operator

Help now

Prior to Java 7, you needed to code the type for a typed collection twice to create the collection. With Java 7 and later, you can use the ____________ operator instead of coding the type a second time.

int[] numList = new int [50]: for (int i = 0; i < 50; i++) numList[i] 2 * i: num[10] = -20; num(30] = 8; 40. What is the value of numList.length in the array above? b. 30 d. 50 41. Which ofthe following statements creates alpha, an anray of 5 components of the type int, and initializes each component to 10? (i) int [] alpha = {10, 10, 10, 10, 10); (ii) int (5] alpha = (10, 10, 10, 10, 10} a. Only (i) b. Only (ii) c. Both (i) and (ii) d. None of these 42. Consider the following declaration. int[] list = (2, 5, 7, 8, 12, 13, 15, 18, 22, 25}; %3D Which of the following correctly finds the sum of the clements of list? () for (int j = 0; j < 10; j++) sum = sum list[j]; for (int j = 1; j <= 10; j++) %3D sum + list [j); uns a. Only (i) b. Only (ii) c. Both (i) and (ii) d. None of these 43. What is the function of the reserved word class? It defines a data type and allocates memory. b. It defines only a data type; it does not allocate memory. It acts as a modifier. a. c. d. It has no function.…
