```
public final class IntArray
extends Object
implements Matrix, org.joda.beans.ImmutableBean, Serializable
```
An immutable array of int values.
This provides functionality similar to List but for int[].
In mathematical terms, this is a vector, or one-dimensional matrix.

public IntArray dividedBy(int divisor)
```
    Returns an instance with each value divided by the specified divisor.
    This is used to divide the contents of this array, returning a new array.
    This is a special case of map(IntUnaryOperator). This instance is immutable and unaffected by this method.
    
    Parameters:
    
    divisor - the value by which the array values are divided
    
    Returns:
    
    a copy of this array with the each value divided by the divisor
  - map
```
public IntArray map(IntUnaryOperator operator)
```
    Returns an instance with an operation applied to each value in the array.
    This is used to perform an operation on the contents of this array, returning a new array. The operator only receives the value. For example, the operator could multiply and add each element.
```
   result = base.map(value -> value * 3 + 4);
 
```
    This instance is immutable and unaffected by this method.
    Parameters:
    
    operator - the operator to be applied

  - mapWithIndex
```
public IntArray mapWithIndex(IntBinaryOperator function)
```
    Returns an instance with an operation applied to each indexed value in the array.
    This is used to perform an operation on the contents of this array, returning a new array. The function receives both the index and the value. For example, the operator could multiply the value by the index.
```
   result = base.mapWithIndex((index, value) -> index * value);
 
```
    This instance is immutable and unaffected by this method.
    Parameters:
