- void changeAll(int x[]) { x[0] = x[0] + 5; return; The first element in an array would be increased by 5 The array would be the same because it was passed by value x would be increased by 5 All the elements in the passed array would be incremented by 5An array index starts with -1 1 0. 2.given the array: int arr[ ][ ] ={ { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 }, { 10, 11, 12 } }; what is in arr[2][1] ? a-11 b-5 c-8 d-9 e-7
- Assume that the following program segment is executed. What is the first element of testArray3 after the execution of the statement sortArray2(testArray3);? *Analyze the statements below: double [] templ = {50.0, 69.0, 75.0, 80.0, 55.0}; printArray (temp1); The call to printArray sends the of/to the array temp1.For an array declartion of int number [25];, what will be the ending index? 0 1 24 25
- In java, the Arrays class contains a static binarySearch() method that returns …… if element is found. false true (-k–1) where k is the position before which the element should be inserted The index of the elementusing java programming int a[] = {5,10,4,20,1,7}; 1- search for the smallest element in array 2-if you found the smallest element in the array :swap the first element with the smallest elementjava getDup accepts an array and returns an int. If there is any element is duplicated, the method counts how many of those present in the array. Example : getDup(["1","2","aa"',"1"]) returns:2 ("1" is duplicated and there are two "1"s so return is 2) class Main { public static int getDup(String[] r) { } public static void main(String[] args) { Scanner in = new Scanner(System.in); String [] strs = new String[in.nextInt()]; for(int i=0; i < strs.length; i++) { strs[i] = in.next(); } System.out.println(getDup(strs)); } } hint: you will need a nested array the will run on the array we get from the method argument. inside the nested loop you will need to check if the main array element is equal to the current
