Behavioral studies by experts have found that leg positions can reveal aspects of our personality. Our legs and feet can provide insights into our subconscious, which is programmed to either move toward what we desire or away from negative emotions such as nervousness, anxiety, boredom, and insecurities. Interesting studies have shown that airline personnel are trained to recognize passengers sitting with crossed ankles as a sign of nervousness or anxiety. During their training, cabin staff are taught to ask these passengers multiple times if they need anything else, as a way to help them open up and relax. Key Traits: Intelligent, Rational Thinker, Punctual, Smart Worker, Cleanliness Lover, Honest but Reserved. It is revealed that  people who sit with knees straight  are perceived as qualified for a job role during their interviews. They are also found to be one who believes in themselves and their skills. They have a healthy and positive outlook toward themselves and as a re...

Concurrent Collection In Synchronized Collection a thread lock the entire list. Only one thread access the entire list at a time. In concurrent collection a threat lock one element, each  element can be accessed by different thread concurrently  Java supported multithreading and concurrency from initiation. Java has introduced the concurrent collection in java 5.0 and java 6.0 over the synchronized collection to improve the performance in a multithreading environment. java has provided concurrent collection API apart from collection API to handle the multithreading and concurrency in a better manner. We can find all the new concurrent collection Interfaces and Classes under the package name java.util.concurrent. In this article, we will focus on some Key interfaces and classes of the java.util.concurrent package. Synchronized Collection V/S Concurrent Collection: Synchronized Collection: Synchronized Collections are slow in performance  Multiple threads can access a syn...

AI vs ML vs DL We are surrounded by multiple technologies. Artificial Intelligence, Machine Learning, Deep Learning, Data Science are common terms nowadays.  People use these terms interchangeably but all these terms are different in terms of definition, application, and limitations.  Nowadays we use many applications that are used in AI. There are many industries that work with AI like Healthcare, E-Commerce, Entertainment, Gaming, Automobile, Education, etc.  Machine Learning and deep learning are used to solve a complex task with huge datasets to make them simple. Artificial intelligence: Artificial Intelligence is a field to make a machine intelligent. AI makes machines to act like human's brains. AI incorporates human intelligence into machines. Intelligence means machines can predict, classify, reason, plan, and perceive like humans. Applications      Self-driving cars like Tesla, Nissan,  Voice Assistants like Siri and Alexa, Amazon Echo Machine...

Java 8 Features 1. forEach() forEach(): method is used to iterate the elements. It takes a single parameter. It is a default method of the Iterable interface. We can pass lambda expressions as an argument. public class ForEachExample {     public static void main(String[] args) {         List<String> list = new ArrayList<String>();         list.add("One");         list.add("Two);         list.add("Three");         list.add("Four");         list.forEach(li -> System.out.println(li));     } } 2. Functional Interfaces and Lambda Expressions Functional Interface The Functional interface contains only one abstract method and also contains a number of default and static methods. Functional Interface is annotated by @FunctionalInterface annotation, it ensures that ...

Java interfaces use to have only abstract methods thanks to JDK 8 which allows the interface to add default and static methods. During the application enhancement or maintenance, it may possible that new methods are required to be added in an interface that forced all implemented classes to be changed and implement new abstract methods. Thus we can add these default methods to existing interfaces without breaking the code and changing old implementation classes. interface DefaultMethod {  public default void defMethod(){    System.out.println("Default Method");  } } public class TestDefault implements DefaultMethod{   public static void main(String[] args) {     TestDefault t = new TestDefault();      t.defMethod();    } } Likewise, you can define  default static methods  in an interface with the restriction of not overriding static methods.

Data Science Data  As we all know the world is rapidly growing in the field of Information Technology and we have to store lots of information in the form of data, that a large amount of data is known as Big Data .  The challenge which comes with big data is storage and access to the right information out of bulk data for business analysis and predictions. Before this era the data was less and stored in a structured manner, nowadays the data is huge and can be structured, unstructured, and semi-structured. Structured, Unstructured, Semi-structured huge data  Cleaning, Processing, Maintaining, Organizing The solution which comes to store the big data is Hadoop and other frameworks, now the main attraction is cleaning, processing, maintaining, organizing and analyzing that data, here the Data Science comes in the role. In short Data Science is extracting meaningful data or information from large and complex datasets. Cleaning, Processing, Maintaining, Organizing Data Analys...
