Since XML and JSON are two popular data interchange formats, you will often need to convert one into other. For example, many SOAP web services returns XML response and if you are using Java and wants to convert that XML response to JSON, then you can use JSON library from https://json.org. It provides a class called XML.java, which provides static methods to convert an XML text into a JSONObject. It also support JSON to XML conversion, which will learn in second part of the article. In order to use this class, you can dowload JAR files from Maven Central repository, or you can add required dependency in your pom.xml file.

How to convert JSON String to Java HashMap? Example
Suppose you have a JSON String, may be a web-service response and you want to create a Map out of it, where key should be the fields and value should be values of those fields e.g. if given JSON String is following :
{
"zip": "90210",
"city": "Beverly Hills"
"state": "CA"
"timeZone": "P"
}
then your HashMap should contain 4 mappings where keys are zip, city, state and timeZone, all of String type and corresponding values.

4 examples to convert Date to LocalDate in Java 8?
One of the challenge you will face while using new Java 8 Date and time API, JSR-310 in existing Java application is the conversion between java.util.Date and java.time.LocalDate and other classes. Even though library has everything you would expect, it doesn't have a direct conversion method between old Date and new LocalDate. There is a reason for it, eventhough java.util.Date says its a date its not, becuase its just a millisecond value since midnight at the start of 1970 GMT. It's equivalent to Instant class in new Java Date API and that's why you have a direct conversion method between Date and Instant in Java 8. Anyway, its not hard to convert a java.util.Date to java.time.LocalDate in Java 8, in fact there are multiple ways which we will explore in this tutorial.

How to Implement Thread in Java with Example
In my opinion, Thread is one of the most important features of the Java programming language which helped it to become the most popular programming language. I remember, when I first started learning Java in one of the programming classes in India how important Thread was a portrait and how much emphasis is given on a clear understanding of multi-threading. It’s still popular and one of most sought after skills in Java programmer because writing concurrent and multi-threaded applications in Java is challenging, despite Java providing excellent support at language level using synchronized and volatile keyword.
