H3 HeadingsH3 Headings tips for javabypatel.blogspot.in: Remember to use H3 tags consistently and appropriately throughout your website content structure, reserving them for distinct sub-topics that logically break down the information presented under a broader H2 category for optimal semantic markup.
In this post we will learn why Hashtable doesn't allow null key and null value while HashMap does.

Creating linked list of Nodes at same level in a Binary tree is same as printing nodes at each level of a Binary tree with only difference is to collect the Nodes in a list for each level instead of printing it. https://javabypatel.blogspot.com/2015/08/binary-tree-traversals-inorder-preorder-postorder-levelorder.html Consider a below Binary Tree, 50 / \ / \ 30 70 / \ / \ 20 40 60 80 / \ 10 25 Output: 50 30 -> 70 20 -> 40 -> 60 -> 80 10 -> 25
Inorder traversal of a Binary Tree reads a Left most element first then a middle or root element and at last the right most element, so when we say successor of a Node, you have to return the next element of the Node in Inorder traversal. Consider a below BST, 50 / \ / \ 30 70 / \ / \ 20 40 60 80 / \ 10 25 Example: Inorder Successor of Node 50 is 60 Inorder Successor of Node 25 is 30 Inorder Successor of Node 40 is 50 Inorder Successor of Node 80 is null Inorder Successor of Node 70 is 80 Inorder traversal of a Binary Search Tree always return the data in sorted order. So one way to find is to do a Inorder traversal which would be 10 20 25 30 40 50 60 70 80 and then you can sequentially search for the next element of the given node which is Inorder successor of a Node. this approach would have O(n) time and space complexity. lets optimize it to O(h) where h is height of tree. (Note: in case of skewed tree it will still be O(n))
In this post we will see what is Min Heap, Max Heap, the operation it supports and the time and space complexity of each operation.
Given the time, calculate the smaller angle between the hour and minute hands on an analog clock in Java.
In this post we will see when to use visitor design pattern and the real life example of visitor design pattern in Java.
In this post we will see how to integrate Swagger in Guice and Jersey to dynamically generate OpenAPI REST endpoint documentation. Sample project uses below libraries, 1. Google Guice 2. Jersey 2. Grizzly server 3. Swagger OpenAPI Annotations
4.0.0 com.javabypatel guice-grizzly-jersey-openapi-swagger-example 1.0-SNAPSHOT 2.3.16 2.30 4.2.2 2.5.0-b61 2.1.5 11 11 com.google.inject guice ${guice.version} org.glassfish.hk2
openapi-configuration.json
This file contains the OpenAPI high-level resource description. you can describe the same using Swagger Annotations.
In this post we will see how to create a Docker image of Spring Boot Microservice using Fabric8 maven plugin. Steps,
1. First we will create a Spring Boot Microservice with some REST endpoints 2. Run the Spring Boot Microservice and access the endpoints to see if it works. 3. Create the docker image of a Microservice created above. 4. Run the Spring Boot Microservice Docker image to see if we can access the REST endpoints.
Download the Spring Boot Microservices Hello World Example from GitHub: spring-boot-docker-hello-world
Create the Docker image of Spring Boot Microservices using Fabric8 maven plugin Run the command, 1. mvn clean install This will create the target directory and place the generated jar of our Microservice inside directory with name "spring-boot-docker-hello-world-0.0.1-SNAPSHOT.jar" 2. mvn fabric8:build This will create the docker image of the Microservice inside the running Docker. run the command below to see existing "docker images"
Inside the target directory, you would see a new folder name Docker containing image tar file.
Run the command, docker run -p 8085:8085 spring-boot-docker-hello-world:0.0.1-SNAPSHOT.dev
