There are differences in languages like Java and Python (for example, in Java, you can use the HashMap interface as a part of the Java collection package). Still, ultimately, most general-purpose languages have a few different ways to implement a hash table. Let's start with the simplest...
The elements will be collected in a map, so we used this Collectors.toMap(). The key is the id and stores the Book object as a value. By printing the result1 as output, we can see that we converted bookList into a Map. import java.util.ArrayList; import java.util.HashMap; import...

Even though I have used an object of the concurrent hash map here, it's not required because unlikekeySet(), thenewKeySet()is a static method. Let's the code to actually generate a concurrent hash set in Java 8: importjava.util.Set;importjava.util.concurrent.ConcurrentHashMap;/* ...
A HashMap is ahash tableimplementation for the Map interface, and as such it defines the basic concepts of key and value: each value is related to a unique key, so if the key for a given key-value pair is already present in the HashMap, its current value is replaced. ...
