In this article, we will discuss 2 different ways to reverse a given linked list using an iterative and recursive way in Java.
In this article, we will discuss the Trie data structure and implement it in Java and perform the search operations.
In this article, we will discuss how to implement the circular linked list in Java and its advantages. We will also see how to perform different operations such as Insertion, Deletion, and Search.
In this article, we will discuss sorting a nearly sorted or K sorted array using Heap data structure in Java.
Algorithm implementation to find the kth largest and smallest element using heap in Java.
n this article, we will implement the algorithm to find the mirror image of a given binary tree in Java.
In this article, we will implement the algorithm to check if a given binary tree is the subtree of another binary tree in Java.
In this article, we will implement the algorithm to check if a given binary tree is a valid binary search(BST) tree or not. We will use a recursive approach in Java to implement the algorithm.
This article gives you an overview of building a few micro services using a spring boot, docker and then deploy them into Kubernetes.
In this article, we will implement the algorithm to print the path from the root node to any given node. We will be using a stack to keep a track of the path and implement the algorithm in Java.
In this article, we will implement the algorithm to find the distance between any two nodes in a binary tree using Java. The basic of this algorithm is to first find the lowest common ancestor of give
In this article, we will implement the algorithm to find the least common ancestor(LCA) of two nodes in a given binary tree in Java. LCA of two nodes is the first common ancestor node of given nodes.
In this article, we will print the top and bottom view of a binary tree. For this, we need to perform vertical order traversal on the tree and then we can easily find out the top and bottom view of it
In this article, we print the left view of a binary tree with level order traversal by using the Queue data structure.
In this article, we will discuss 3 different techniques for Level Order Traversal of a binary tree. This technique can be used to find the left and right view of the tree.
In this article, we will discuss about different hashing techniques and collision conditions. We will list out different collision resolution techniques and discuss about closed addressing technique.
In this article, we will discuss about how we can implement Dijkstra algorithm in Java to find the shortest paths between nodes in a graph.
This turorial is about building Angular 6 application step by step.We will be building a sample login application with CRUD operations post-login with sample REST APIs.We will be also integrating HttpClientModule and RouterModule.
The tutorial is about creating a full stack app using angular5 JWT authentication with spring boot security in the server as token provider and HTTPInterceptor implementation. Access of REST API is given to HTTP request having auth token in the header.
This tutorial is about creating a sample application using angular 5 material design.To develop this app we will be using different angular 5 material components such as form controls, navigation menu, layout and buttons.
This tutorial is about Spring Boot, Angular 5 and spring data integration with CRUD example.We will be using spring boot 1.5 to expose REST APIs and angular5 with routing to build our client using angular CLI.It also provides mysql database integration for CRUD operation.
Implement JWT authentication with Spring Boot and maven.Using OncePerRequestFilter class to define custom authentication mechanism to URLs as well as for methods.
Implementation of Spring Boot Security OAuth2 with CRUD example to secure REST APIs.Implementation of AuthorizationServer,ResourceServer with mysql db and spring data. BCryptPasswordEncoder is used for password encoding.
This tutorial is about spring boot multiple database configurations using properties file.The example here defines multiple datasource configurations and spring data JPA uses corresponding entitymanager to query multiple databases.
This tutorial explains integration of spring boot 1.5 and hibernate 5 + mysql with REST examples. It discusses about creating hibernate session factory using spring-boot-starter-data-jpa artifact.
This post shows examples of Spring Boot Actuator REST endpoints with with sample code base.It also talks about customizing endpoints, securing endpoints and also creating custom endpoints using AbstractEndpoint
Secure Spring REST API with basic authentication using spring Boot security.The REST Apis are exposed using spring controller and the application is tested using postman.
