In this quick Java tutorial, we learned to create an immutable or unmodifiable Map using the factory method added in Java 9 and later. We also learned to create immutable maps using the Java 8 APIs. Happy Learning !!
So ,in this tutorial, we saw how we can create immutable map in Java.This is really useful when we know that content of our map is not going to change in future.We saw how JDK has various methods to create immutable maps. Thanks for reading. Subscribe to our blog for more such inter...
To begin, you will create a map of the world’s capitals. Each entry in thecapitalsmap will have a key with the country name and a value with the capital name. This is a good example because every country has a unique name and thus the keys cannot overlap. Also, each country has on...

Yes, this is possible now. In Java 9 a couple of factory methods have been added that simplify the creation of maps : // this works for up to 10 elements: Map<String, String> test1 = Map.of( "a", "b", "c", "d" );
2. Standard Maps Java has several implementations of the interfaceMap, each one with its own particularities. However,none of the existing Java core Map implementations allow aMapto handle multiple values for a single key. As we can see, if we try to insert two values for the same key, th...
In this tutorial, we’ll discuss how to use Java’s built-in classes, third-party libraries, and our custom implementation to create an Entry object that represents a key-value association in a Map. 2. Using Java Built-in Classes Java provides the Map.Entry interface with two simple implem...
