A **`LinkedHashMap`** is the same as `HashMap`, except the `LinkedHashMap` maintains the insertion order, whereas the `HashMap` doesn’t. Internally the `LinkedHashMap` uses the doubly-linked list to maintain the insertion order. 
>Read more about `LinkedHashMap` [here](https://docs.oracle.com/javase/8/docs/api/java/util/LinkedHashMap.html).

The `get` method of `LinkedHashMap` will: 

* Return the `Value` associated with the passed `key` if there is a mapping present for the passed `key`.

* Return `null` if there is no mapping present for the passed `key`.

#   
#  Syntax

```java
public V get(Object key)
```

##  
## Code

The code below demonstrates how to use the `get` method.


import java.util.LinkedHashMap;

class GetExample {
    public static void main(String[] args) {

        // create an LinkedHashMap
        LinkedHashMap<Integer, String> numbers = new LinkedHashMap<>();

        numbers.put(1, "One");
        numbers.put(2, "Two");
        System.out.println("The LinkedHashMap is - " + numbers);

        System.out.println("\nGetting value for key 1 :" + numbers.get(1));
        System.out.println("\nGetting value for key 5 :" + numbers.get(5));

    }
}

In the code above, we: 
* Create a `LinkedHashMap` object with the name `numbers`.
* Add two entries to the `numbers`.

* Call the `get` method for the key `1`. This will return the value associated with the key `1`. In our case `one` is returned.

* Call the `get` method for the key `5`. This will return `null` because there is no value associated for the key `5`. 

What is the LinkedHashMap.get method in Java?

The LinkedHashMap's get method retrieves the value for a given key or returns null if no mapping exists.
