Difference between first level and second level cache in Hibernate

The main difference between the first level and second level cache in Hibernate is that the first level is maintained at the Session level and accessible only to the Session, while the second level cache is maintained at the SessionFactory level and available to all Sessions. This means, you can use the first level cache to store local data, i.e. the data which is needed by the Session, and you can use the second-level cache to store global data, i.e. something which can be shared across sessions. This is also one of the frequently asked Hibernate Interview questions and accessible in both telephonic rounds as well as on face to face interview, in both fresher and experienced level interviews.

Top 5 Free Courses to learn Node.js in 2021 - Best of lot

Node JS has completely changed the way JavaScript is used for development. Earlier JavaScript was considered as a client-side language because it runs on a browser and mostly used for client-side validations, animations, and interaction. Node.js takes that to the next level by allowing JavaScript to run on a server-side, which means you can now write JavaScript applications that can execute without a browser. Node JS uses Google Chrome's execution engine and asynchronous processing to do this. All you need to is include a node.js script in your application, and you are ready to create server-side applications in JavaScript, which wasn't possible until a few years back.

Difference between save(), saveOrUpdate() and persist() in Hibernate Session

The Session interface in Hibernate provides a couple of methods to move an object from a new or transient state to a persistent state e.g. save(), saveOrUpdate(), and persist() are used to store an object into the database, but there are some significant differences between them. The Session.save() method does an INSERT to store the object into the database and it also returns the identifier generated by the database. On the other hand, saveOrUpdate() can be used to reattach a detached object in Hibernate Session i.e. it can do INSERT or UPDATE depending upon whether an object exists in the database or not.

10 Examples of forEach() method in Java 8

From Java 8 onward, you can iterate over a List or any Collection without using any loop in Java. The new Stream class provides a forEach() method, which can be used to loop over all or selected elements of the list and map. The forEach() method provides several advantages over the traditional for loop e.g. you can execute it in parallel by just using a parallel Stream instead of regular stream. Since you are operating on stream, it also allows you to filter and map elements. Once you are done with filtering and mapping, you can use forEach() to operate over them. You can even use the method reference and lambda expression inside forEach() method, resulting in a more clear and concise code.

Spring HelloWorld Example in Java using Annotation and Autowiring

Spring framework has gone a couple of releases since I last share the Spring hello world example with XML configuration. In this article, I am going to explain to you how to create a Spring hello world example with Spring 4.2 release and by using Annotation for dependency injection and autowiring. So no more XML files to specify bean dependencies. It's a simple program that shows how you can use the Spring framework to create Services that are loosely coupled. The example will show you the basic concept of dependency injection by creating a simple Java application that greets the user. It's actually a little bit complex version of a simple Helloworld program but if you need decoupling and in-direction you need to accept some level of complexity. That's the price you need to pay to achieve the flexibility in your code.

How to Reverse String in Java with or without StringBuffer Example

Reverse String in Java

There are many ways to reverse a given String in Java. For example, you can use rich Java API to quickly reverse the contents of any String object. Java library provides StringBuffer and StringBuilder class with the reverse() method which can be used to reverse String in Java. Since converting between String and StringBuffer or StringBuilder is very easy it's the easiest way available to reverse String in Java. But, in a coding interview, you may not be allowed to use the JDK API methods to solve this problem. That's why, writing a Java program to reverse String in Java without StringBuffer is one of the popular Java String interview questions, which requires you to reverse String by applying logic and by not using API methods.

Since there was no competition for Spring security and it does its job very well, it soon becomes the de-facto standard for implementing security in both Java web applications, REST APIs, and core Java applications. The rise of the Spring framework certainly helps it to cement its place as well.

Merge Sort in Java - Algorithm Example and Tutorial

The merge sort algorithm is a divide and conquers algorithm. In the divide and conquer paradigm, a problem is broken into smaller problems where each small problem still retains all the properties of the larger problem -- except its size. To solve the original problem, each piece is solved individually; then the pieces are merged back together. For example, imagine you have to sort an array of 200 elements using the bubble sort algorithm. Since selection sort takes O(n^2) time, it would take about 40,000-time units to sort the array. Now imagine splitting the array into ten equal pieces and sorting each piece individually still using selection sort. Now it would take 400-time units to sort each piece; for a grand total of 10*400 = 4000.

How to Rotate an Array to Left/Right by a Given Number in Java - Coding Problem

Hello guys, welcome to another post with another array-based coding problem. In the last article, we've learned about finding missing numbers in the array with duplicates, and today we'll solve the problem of rotating an array by left or right by a given number. For example, suppose an integer array {1, 2, 3} is given and it was asked to rate this array to the left by 3 then the result array will look like {2, 3, 1} because it was rotated twice on left. Similarly, if you are asked to rotate the same array twice by right then you'll get {1, 2, 3}, the same array is back. This is an interesting problem and it's quite easy to solve but I have seen many programmers struggle with this one as well. So, a little bit of practice and learning will not hurt.

Top 5 Free Database and SQL Query Courses for Programmers to Learn Online - Best of Lot

Hello guys, I have been sharing some free programming resources e.g. books and courses in this blog for quite some time. Earlier I have shared free courses on Java, Maven, Spring, and Data Structure and Algorithms and today I'll share some of the free online training courses to learn SQL and Database. Why you should learn SQL? Well, it's one of the must-have skills for programmers, application developers, and IT professionals. Like Linux, this is one skill that is going to serve you longer than any other programming language, framework, or library. The SQL is used to interact with Database Systems like Oracle, MySQL, and Microsoft SQL Server. As per ANSI (American National Standards Institute), SQL stands for the Standard Query language for Relational Database Management Systems.
