After completing this course, you’ll be well versed in all the functionality of Java 8 and be ready to utilize these new features in your own code.

Java 8 for Experienced Developers: Lambdas, Stream API & Beyond

If you have used `Map` then you must have faced a challenge where you needed to update the value of a key in the `Map`. Now, before updating, you must first check if the value is present in the `Map`, get the current value, update it, and again put the value in the `Map`. This is quite a cumbersome process, and it involves using lots of if/else statements. This kind of code is difficult to understand and fix if any issues occur.

Thankfully, Java 8 has introduced some new methods in the `Map` interface to make our lives easier. In this lesson, we will discuss some of those new methods.

# `1. getOrDefault()`

This method is a lifesaver if you need to update a certain key in the `Map`. The `getOrDefault()` method either returns the value of the key, or it returns the default value if the key is not present.

This lesson explains the new methods added in Map API for fetch operations.
