The **`asIntBuffer()` method** of the `ByteBuffer` class in Java creates a view of a given `ByteBuffer` object as an `IntBuffer`.

The content of `IntBuffer` starts from `ByteBuffer`'s current buffer position. Any changes made to `ByteBuffer` are reflected in `IntBuffer`, and vice versa. 

The `position`, `mark`, and `limit` values of the two buffers are independent. 

The process is illustrated below:

To use the `asIntBuffer()` method, you will need to include the `ByteBuffer` class in your program, as shown below:

```Java
import java.nio.ByteBuffer
```

The prototype of the `asIntBuffer()` method is shown below:

```Java
public abstract IntBuffer asIntBuffer()
```
# 
#  Parameters

The `asIntBuffer()` method does not accept any parameters.

# 
## Return value

The `asIntBuffer()` method returns a new `IntBuffer` object that is a view of a specified `ByteBuffer` object.

The properties of the newly created `IntBuffer` object are as follows:

* The current buffer position is set to $0$.
* `capacity` and `limit` are defined as the number of bytes that remain in the `ByteBuffer` object divided by $4$.
* The `mark` value is undefined.
* `IntBuffer` will be `direct` if, and only if, the `ByteBuffer` object is `direct`. Similarly, `IntBuffer` will be `read-only` if, and only if, the `ByteBuffer` object is `read-only`. 

##
## Example

The code below shows how the `asIntBuffer()` method can be used in Java:

import java.nio.*;
import java.util.*;

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

    // initialize ByteBuffer instance
    ByteBuffer sourceBuffer = ByteBuffer.allocate(16);
    
    // get int buffer view
    IntBuffer newBuffer = sourceBuffer.asIntBuffer();

    int values[] = {2, 1, 6};

    // add values to buffer
    for(int i = 0; i < 3; i++)
    {
      newBuffer.put(values[i]);
    }

    // set buffer position to first index
    newBuffer.rewind();

    // print source buffer
    System.out.println("The ByteBuffer is: " + Arrays.toString(sourceBuffer.array()));
    
    //print new buffer
    int i;
    System.out.print("The IntBuffer is: [");
    while ((i = newBuffer.get()) != 0)
    {
      System.out.print(i + " ");
    }
    System.out.print("]");
    
  }
}

## Explanation

* First, a `ByteBuffer` object, `sourceBuffer`, is initialized through the `allocate()` method. `sourceBuffer` has the capacity to store $16$ elements.

* Next, an `IntBuffer` view of `sourceBuffer` is created through the `asIntBuffer()` method in line $11$.

* The `put()` method is repeatedly invoked through a `for-loop` to add values to `newBuffer`.

* All the changes made to `newBuffer` are also reflected in `sourceBuffer`. However, since `sourceBuffer` holds byte elements, each integer value added to `newBuffer` is the equivalent of $4$ byte values added to `sourceBuffer`.

> For example, the addition of the element $2$ to `newBuffer` is reflected by the addition of $4$ elements, i.e., $[0, 0, 0, 2]$, to `sourceBuffer`.



What is the ByteBuffer asIntBuffer() method in Java?

Creates an IntBuffer view of a ByteBuffer, reflecting mutual changes, with independent position, mark, and limit values.
