Example com.tutorialspoint.project Class Naming Convention When naming classes in Java, it's essential to start the class name with an uppercase letter. ... Read More
In this article, we will understand how to find common elements in two array-list. The class ArrayList extends AbstractList and implements the List interface. ArrayList supports dynamic arrays that can grow as needed.Array lists are created with an initial size. When this size is exceeded, the collection is automatically enlarged. When objects are removed, the array may be shrunk.Below is a demonstration of the same −Suppose our input is −First list: [Java, Scala, Shell, JavaScript] Second list: [Java, Python, Shell]The desired output would be − The common elements from the two lists are: [Java, Shell] Steps to Find Common Elements ...

LinkedHashSet is a class provided by Java that implements Set Interface. The first element of a LinkedhashSet is nothing but the first element in the collection. In this article, we will discuss different approaches to get the first element from LinkedHashset. What is a LinkedHashSet? A LinkedHashSet is a collection which is a combination of HashSet collection and a LinkedList collection. A HashSet is an unordered collection and also doesn’t allow duplicates. A LinkedList stores duplicates but also is an ordered collection i.e., it stores the elements in a way in which add elements to the collection. Coming to ... Read More
LinkedHashSet is a class provided by Java which Implements Set Interface. LinkedHashSet is implemented as a hash table with a linked list running through it, so it is more efficient that HashSet and also maintains orders. It is useful when you need a collection that maintains order and does not allow duplicates. In this section, we will discuss different approaches to get the elements from LinkedHashset by index. What is a LinkedHashSet? A LinkedHashSet is a collection which is a combination of HashSet collection and a LinkedList collection. A HashSet is an unordered collection and also doesn’t allow duplicates. ... Read More
In this article, we are going to learn about the different sorting techniques and their implementations in C language. The following are the sorting techniques that we can implement with C language and other programming also: Bubble Sort Insertion Sort Selection Sort Merge Sort Shell Sort Heap Sort Bucket Sort Counting Sort Radix Sort Quick Sort Bubble Sort using C Bubble Sort is an elementary sorting algorithm, which works by repeatedly exchanging adjacent elements, if necessary. When no exchanges are required, the file is sorted. Example of Bubble Sort using C #include void bubbleSort(int array[], ... Read More

We will discuss the difference between procedural programming languages and functional programming languages. Procedural Programming Languages Procedural programming languages have functions which you have to define. These functions need to have a set of instructions which should be executed when the function is called. You have to think about each instruction that you ... Read More
Programming languages can be interpreted or compiled. The compiled languages are not interpreted and there is no need to compile the interpreted languages. In this article, we will discuss the difference between compiled and interpreted languages. Compiled Programming Languages Compiled programming languages are the languages in which the code has to be compiled to convert it into machine language. This helps the processor execute the code and provide the result. C, C++, C#, Java, etc. are some of the languages which have to be compiled and then executed. What is Compile? Compile is a process which is used to convert ... Read More
