### class:Array [NONE]
    public final class Array
    extends Object
The `Array` class provides static methods to dynamically create and access Java arrays. `Array` permits widening conversions to occur during a get or set operation, but throws an `IllegalArgumentException` if a narrowing conversion would occur. Since: 1.1

### method:newInstance(java.lang.Class,int) [NONE]
- > ### newInstance public static Object newInstance?(Class<?> componentType, int length) throws NegativeArraySizeException Creates a new array with the specified component type and length. Invoking this method is equivalent to creating an array as follows:
  >      int[] x = {length};
  >      Array.newInstance(componentType, x);
The number of dimensions of the new array must not exceed 255. Parameters: `componentType` - the `Class` object representing the component type of the new array `length` - the length of the new array Returns: the new array Throws: `NullPointerException` - if the specified `componentType` parameter is null `IllegalArgumentException` - if componentType is `Void.TYPE` or if the number of dimensions of the requested array instance exceed 255. `NegativeArraySizeException` - if the specified `length` is negative

### method:newInstance(java.lang.Class,int...) [NONE]
### newInstance public static Object newInstance?(Class<?> componentType, int... dimensions) throws IllegalArgumentException, NegativeArraySizeException Creates a new array with the specified component type and dimensions. If `componentType` represents a non-array class or interface, the new array has `dimensions.length` dimensions and `componentType` as its component type. If `componentType` represents an array class, the number of dimensions of the new array is equal to the sum of `dimensions.length` and the number of dimensions of `componentType`. In this case, the component type of the new array is the component type of `componentType`. The number of dimensions of the new array must not exceed 255. Parameters: `componentType` - the `Class` object representing the component type of the new array `dimensions` - an array of `int` representing the dimensions of the new array Returns: the new array Throws: `NullPointerException` - if the specified `componentType` argument is null `IllegalArgumentException` - if the specified `dimensions` argument is a zero-dimensional array, if componentType is `Void.TYPE`, or if the number of dimensions of the requested array instance exceed 255. `NegativeArraySizeException` - if any of the components in the specified `dimensions` argument is negative.
