方法详细资料

isNotEmpty

public static boolean isNotEmpty(CharSequence cs)

isEmpty

public static boolean isEmpty(CharSequence cs)

addAll

public static <T> T[] addAll(T[] array1,
                             T... array2)

copy from commons-lang3

Adds all the elements of the given arrays into a new array.

The new array contains all of the element of array1 followed by all of the elements array2. When an array is returned, it is always a new array.

 ArrayUtils.addAll(null, null)     = null
 ArrayUtils.addAll(array1, null)   = cloned copy of array1
 ArrayUtils.addAll(null, array2)   = cloned copy of array2
 ArrayUtils.addAll([], [])         = []
 ArrayUtils.addAll([null], [null]) = [null, null]
 ArrayUtils.addAll(["a", "b", "c"], ["1", "2", "3"]) = ["a", "b", "c", "1", "2", "3"]
 

类型参数:

T - the component type of the array

参数:

array1 - the first array whose elements are added to the new array, may be null

array2 - the second array whose elements are added to the new array, may be null

返回:

The new array, null if both arrays are null. The type of the new array is the type of the first array, unless the first array is null, in which case the type is the same as the second array.

抛出:

IllegalArgumentException - if the array types are incompatible

clone

public static <T> T[] clone(T[] array)

commons-lang3

Shallow clones an array returning a typecast result and handling null.

The objects in the array are not cloned, thus there is no special handling for multi-dimensional arrays.

This method returns null for a null input array.

类型参数:

T - the component type of the array

参数:

array - the array to shallow clone, may be null

返回:

the cloned array, null if null input
