How to Convert String to LocalDate, LocalTime, LocalDateTime and ZonedDateTime in Java? Example Tutorial

The JDK 8 added a new Date and Time API (JSR 310) which introduces new date and time classes like LocalDateLocalTime, LocalDateTime, and ZonedDateTime. Now, if you have a String e.g. "2016-12-14 03:30" then how do parse it to LocalDate, LocalTime, LocalDateTime and ZonedDateTime? Similarly, if you have an instance of those classes how you can format to the String you want e.g. in dd/MM/yyyy format, or USA or UK format? Well, Java 8 provides a utility class called DateTimeFormatter which can be used to parse/format dates in Java 8. It also provides several built-in formatter e.g. ISO date format and other to facilitate formatting of dates to String.

How to convert JSON to Map in Java 8 without using third party libraries like Jackson or Gson

Hello guys, If you are working with JSON data then you may know that JSON is collection of key value pairs and that's why many times, you also need to convert them into a Map in Java. While there are many Java libraries like Jackson and Gson which provides support of parsing JSON to Java objects, there is not much support for JSON parsing or manipulation on standard JDK. While JSON parsing is still a long overdue, starting with JDK 8u60+ the built-in Nashorn engine is capable to convert JSON content into java.util.Map. No external dependencies are required for parsing JSON in to Map as you will learn in this article.

Can You Override static method in Java? Method Hiding Example

Can we override the static method in Java?
This is one of the most popular Java interview questions. The answer to this question is No, you cannot override the static method in Java because the method overriding is based upon dynamic binding at runtime and static methods are bonded using static binding at compile time. This means static methods are resolved even before objects are created, that's why it's not possible to override static methods in Java. Though you can declare a method with the same name and method signature in the subclass which does look like you can override static methods in Java but in reality that is method hiding.

Top 30 Stack and Queue Data Structure Interview Questions for Practice

Hello guys, stack and queue are two fundamental data structures which are used on many applications and algorithms. For example, you can use stack to convert a recursive algorithm to iterative one, which is more safe in production and no risk of StackOverFlowError. Similarly, queue is used in many asynchronous algorithms like producer consumer pattern or publish subscribe pattern to exchange messages. Because of that, they are also quite popular on coding interviews, particularly on Java developer interviews. In the past, I have shared 100+ data structure questions as well as String coding problems, array questions, linkedlist questions, recursion questions and even dynamic programming questions but I have not shared stack and queue related questions before.
