![]() ![]() Linear search and Binary search are examples of search techniques. Searching means to search for a term or value in an array.īubble sort and Selection sort are examples of sorting techniques. Sorting means to arrange the elements of the array in ascending or descending order. Int a is an array of int data type that can hold 10 integer values whereas char a is an array of char data type that can hold 10 characters. it stores values in the memory reserved for the array elements. Array Initialisation assigns values to the array elements i.e. Write a program to initialise the given data in an array and find the minimum and maximum values along with the sum of the given elements.Īrray declaration tells the compiler about the size and data type of the array so that the compiler can reserve the required memory for the array. search, the algorithm uses the middle value of the array for the search operation. Binary search is as efficient as the sequential search.Binary search is more efficient than the sequential search.Binary search is less efficient than the linear search.Binary search is less efficient than the sequential search.Which of the following statements is true? can be used with both sorted and unsorted arrays.can be used with both sorted and unsorted arrays ✓.The size of an array that signifies the number of elements it can store is given using.

Un-object-oriented public static void main and replace it with To make effective use of BlueJ, you want to eliminate the very (You can call static methods without instantiating the To investigate the object, right-click on it and startĬalling methods. The object is created on the "object workbench" below theĬlass display. To instantiate an object, right-click on the class and select an The biggest difference between BlueJ and traditional developmentĮnvironments is that BlueJ isn't concerned with running programs. To run an applet, right-click on the appletĬlass and select "Run applet." However, if you just use BlueJ asĪ program launcher, you do not take full advantage of its capabilities.
