In this shot, we will learn how to use the **`TreeMap.get()`** method in Java.

#    
## Introduction
The `TreeMap.get()` method is present in the `TreeMap` class inside the `java.util` package.

The `TreeMap.get()` method is used to obtain the value associated with the given key on the `TreeMap`.
If no such key is present in the `TreeMap`, the method returns `null`.


## Syntax
The syntax of the `TreeMap.get()` method is given below:
```
V TreeMap.get(K key);
```

## Parameters
The `TreeMap.get()` method accepts one parameter:
* `Key`: The key for which we need to determine the associated value.


## Return value
The `TreeMap.get()` method can return one of values mentioned below:
* `Value`: Returns the value associated with that key.
* `NULL`: If no such key is present in the `TreeMap`.

## Code

Let's have a look at the code.

import java.util.*;
class Main 
{
  public static void main(String[] args)
  {
    TreeMap<Integer, String> t1 = new TreeMap<Integer, String>();

    t1.put(1, "Let's");
    t1.put(5, "see");
    t1.put(2, "TreeMap class");
    t1.put(27, "methods");
    t1.put(9, "in java.");

    System.out.println("The value for key = 2 is: " + t1.get(2));
    System.out.println("The value for key = 11 is: " + t1.get(11));
  }
}


#    
## Explanation
* In line 1, we import the required package.

* In line 2, we make a `Main` class.

* In line 4, we make a `main()` function.

* In line 6, we declare a `TreeMap` that consists of keys of type `Integer` and values of type `String`.

* From lines 8 to 12, we use the `TreeMap.put()` method to insert values in the `TreeMap`.

* In line 14, we use the `TreeMap.get()` method to get the value for $key = 2$.

* In line 15, we use the `TreeMap.get()` method to get the value for $key = 11$. This key is not present, so we get the output value as `NULL`.



So, this is the way to use the `TreeMap.get()` method in Java.

What is the TreeMap.get() method in Java?

TreeMap.get() returns the value for a specified key or null if the key is absent.
