public class ArrayUtils
extends java.lang.Object
```
Operations on arrays, primitive arrays (like int[]) and primitive wrapper arrays (like Integer[]).
This class tries to handle null input gracefully. An exception will not be thrown for a null array input. However, an Object array that contains a null element may throw an exception. Each method documents its behaviour.

                                           java.lang.Object array2)
```
    Deprecated. this method has been replaced by java.util.Objects.deepEquals(Object, Object) and will be removed from future releases.
    
    Compares two arrays, using equals(), handling multi-dimensional arrays correctly.
    Multi-dimensional primitive arrays are also handled correctly by this method.
    
    Parameters:
    
    array1 - the left hand array to compare, may be null
    
    array2 - the right hand array to compare, may be null
    
    Returns:
    
    true if the arrays are equal
  - toMap
```
public static java.util.Map<java.lang.Object,java.lang.Object> toMap(java.lang.Object[] array)
```
    Converts the given array into a Map. Each element of the array must be either a Map.Entry or an Array, containing at least two elements, where the first element is used as key and the second as value.
    This method can be used to initialize:
```
 // Create a Map mapping colors.
 Map colorMap = ArrayUtils.toMap(new String[][] {
     {"RED", "#FF0000"},
     {"GREEN", "#00FF00"},
     {"BLUE", "#0000FF"}});
 
```
    This method returns null for a null input array.
    Parameters:
    
    array - an array whose elements are either a Map.Entry or an Array containing at least two elements, may be null
    
    Returns:
    
    a Map that was created from the array
    
    Throws:
    
    java.lang.IllegalArgumentException - if one element of this Array is itself an Array containing less then two elements
    
    java.lang.IllegalArgumentException - if the array contains elements other than Map.Entry and an Array
  - toArray
```
public static <T> T[] toArray(T... items)
```
    Create a type-safe generic array.
    The Java language does not allow an array to be created from a generic type:
```
    public static <T> T[] createAnArray(int size) {
        return new T[size]; // compiler error here
    }
    public static <T> T[] createAnArray(int size) {
        return (T[]) new Object[size]; // ClassCastException at runtime
    }
 
```
    Therefore new arrays of generic types can be created with this method. For example, an array of Strings can be created:
```
    String[] array = ArrayUtils.toArray("1", "2");
    String[] emptyArray = ArrayUtils.<String>toArray();
 
```
    The method is typically used in scenarios, where the caller itself uses generic types that have to be combined into an array.
    Note, this method makes only sense to provide arguments of the same type so that the compiler can deduce the type of the array itself. While it is possible to select the type explicitly like in Number[] array = ArrayUtils.<Number>toArray(Integer.valueOf(42), Double.valueOf(Math.PI)), there is no real advantage when compared to new Number[] {Integer.valueOf(42), Double.valueOf(Math.PI)}.
    Type Parameters:
    
    T - the array's element type
    
    Parameters:
    
    items - the varargs array items, null allowed
    
    Returns:
    
    the array, not null unless a null array is passed in

For any element-to-be-removed specified in greater quantities than contained in the original array, no change occurs beyond the removal of the existing matching items.
    This method returns a new array with the same elements of the input array except for the earliest-encountered occurrences of the specified elements. The component type of the returned array is always the same as that of the input array.
