One of the great features of Java 8 is the new Date and Time API which is intended to fix existing issues related to mutability and thread-safety with existing java.util.Date class. But given java.util.Date is used very heavily across all the Java application, you will often end up with a situation where you need to convert java.uti.Date to java.time.LocalDate while working in Java 8. Unfortunately there is no toLocalDate() method in the java.util.Date class. Though, you can easily convert Date to LocalDate if you are familiar with how new and old API classes map to each other.

Java 8 Stream + Map Examples - Functional Programming and Coding
The map is a well known functional programming concept that is incorporated into Java 8. Map is a function defined in java.util.stream.Streams class, which is used to transform each element of the stream by applying a function to each element. Because of this property, you can use a map() in Java 8 to transform a Collection, List, Set, or Map. For example, if you have a list of String and you want to convert all of them into upper case, how will you do this? Prior to Java 8, there is no function to do this. You had to iterate through List using a for loop or foreach loop and transform each element. In Java 8, you get the stream, which allows you to apply many functional programming operators like the map, reduce, and filter.

What is Overloading, Overriding, Hiding, Shadowing and Obscuring in Java and Object-Oriented Programming?
Hello guys, today, I am going to explain a couple of fundamental object-oriented programing concepts in Java like Overloading, Overriding, Hiding, Shadowing, and Obscuring. The first two are used in the context of a method in Java while the last three are used in the context of variables in Java. Two methods with the same name and same class but the different signature is known as overloading and the method is known as an overloaded method while a method with the same name and same signature but in parent and child class is known as overriding. On the other hand, Hiding is related to overriding since the static and private method cannot be overridden, if you declare such methods with same name and signature in parent and child class then the method in the child class will hide the method in the parent class.
