**`AbstractMap.get()`** is a method of the Java AbstractMap class. We use it to return the value a specified key maps to in the AbstractMap maps, or to return `NULL` if the AbstractMap contains no mapping for the specified key.

# Syntax

```
AbstractMap.get(Object key);
```

The `AbstractMap.get()` method takes one parameter, #key# key: of type `Object` #key#, mapped to the supposed return value.

# Code

We can write the illustration shown above in the code snippet below.


import java.util.*;

class AbstractMapDemo {
    public static void main(String[] args)
    {
  
        // Creating an AbstractMap
        AbstractMap<Integer, String>
            abstractMap = new HashMap<Integer, String>();

        // Mapping string values to int keys
        abstractMap.put(21, "Shot");
        abstractMap.put(42, "Java");
        abstractMap.put(34, "Yaaaayy");
    
        // Printing the AbstractMap
        System.out.println("The Mappings are: "
                           + abstractMap);
  
        // Getting the value of key 21
        System.out.println("The value of key 21 is: "
                           + abstractMap.get(21));

        // Getting the value of key 35
        System.out.println("The value of key 34 is: "
                           + abstractMap.get(35));
  
        
    }
}


What is AbstractMap get() in Java?

Returns the value a specified key maps to in AbstractMap or NULL if no mapping exists.
