Sorting: This one is for arranging the data items in some order, such as in ascending or descending order of numerical data and in dictionary order if alphanumeric data. Searching: This can be used to find out the location of the data item if that particular item exists in the given collection of data items.Traversal: This can be used to access each data item only once before it is processed.Deletion: This is used to delete an already available data item from the existing set of data items.Insertion: This is used to add a new data item in the existing set of data items.Operations that can be performed on data structures are as below: Describe some of the operations that are performed on different Data Structures? Let us now have a look at the advanced Interview Questions and Answers. Part 2 – Data Structure Java Interview Questions (Advanced) There are many ways available to reverse String in Java or other programming languages one could do so by using built-in functions such as reverse() from the StringBuffer class. After this, one should subtract the actual sum to the expected sum, and that is how duplicate numbers can be found. To get the answer, one can simply add all numbers stored in that particular array, and the total sum should be equal to n(n+1)/2. These are the common Data Structure Java Interview Questions asked in an interview. How to find a duplicate number in an integer array between 1 to 100 numbers? If the same trick as above of maintaining two pointers is applied where one pointer increments, when first has moved up to the 3rd element, then in that case when the first pointer reaches to the end of the given linked list, the second pointer will be pointing to the 3rd element of the list from last. How to identify the third element from the end in a linked list in one pass? Let us move to the next Data Structure Java Interview Questions. This happens only if a linked list consists of a loop or cycle. If two pointers are maintained, and one of them is incremented after processing two nodes and the other after processing every node, it is likely that we find a situation where both the pointers are pointed to the same node. One of these pointers will increment at each node while the other will increment after two nodes simultaneously thus, by having this type of arrangement, when the first pointer reaches the end of the linked list, the second pointer will point to a middle element of the linked list. In order to find the middle element of the linked list in one pass, one needs to maintain a two-pointer. How do you find the middle element of the linked list in one pass? This first part covers basic Interview Questions and Answers. These interview questions are divided into two parts are as follows: Part 1 – Data Structure Java Interview Questions (Basic) In this 2022 Data Structure Java Interview Questions article, we shall present the 10 most important and frequently asked Data Structure Java interview questions.
