a) The method finds the number of times a given value occurs in a given subrange between from (inclusive) and to (exclusive) within an array of integers.
b) The method finds the largest value stored in an array of integers.
c) The method removes every other String from an array of Strings, and stores the results in a newly constructed array.
d) The method puts the elements of an existing array in random order.
e) The method creates an array of int of a given size with randomly generated elements between small (inclusive) and large (exclusive).
Explanation / Answer
a) The method finds the number of times a given value occurs in a given subrange between from (inclusive) and to (exclusive) within an array of integers.
Answer: public int subrange(int a[], int inclusive, int exclusive);
b) The method finds the largest value stored in an array of integers.
Answer: int max(int a[]);
c) The method removes every other String from an array of Strings, and stores the results in a newly constructed array.
Answer: String[] removeString(String s[], String other);
d) The method puts the elements of an existing array in random order.
Answer: void randomOrder(int a[]);
e) The method creates an array of int of a given size with randomly generated elements between small (inclusive) and large (exclusive).
