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);

newInstancetop

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 the number of array dimensions supported by the implementation (typically 255).

Parameters:: @param componentType the Class object representing the component type of the new array; @param dimensions an array of int types representing the dimensions of the new array
Return:: @return the new array
Exceptions:: @exception NullPointerException if the specified componentType argument is null; @exception IllegalArgumentException if the specified dimensions argument is a zero-dimensional array, or if the number of requested dimensions exceeds the limit on the number of array dimensions supported by the implementation (typically 255), or if componentType is Void.TYPE.; @exception NegativeArraySizeException if any of the components in the specified dimensions argument is negative.
