convertPrimitiveArrayToObjectArray

public static Object[] convertPrimitiveArrayToObjectArray(Object value)

将primitive对象数组转换为object类型数组

参数：

value -

返回：

toArray

public static Object[] toArray(Object... objects)

构造数组对象

参数：

objects -

返回：

toArray

public static Object[] toArray(Object o1,
                               Object[] o2)

isArray

public static boolean isArray(Object o)

判断对象是数组类型

参数：

o -

返回：

isCollOrArray

public static boolean isCollOrArray(Object o)

判断对象是数组类型或者集合类型

参数：

o -

返回：

sizeOf

public static int sizeOf(Object o)

toString

public static String toString(long[] a)

toString

public static String toString(int[] a)

toString

public static String toString(short[] a)

toString

public static String toString(char[] a)

toString

public static String toString(byte[] a)

toString

public static String toString(boolean[] a)

toString

public static String toString(float[] a)

toString

public static String toString(double[] a)

toString

public static String toString(Object[] a)

toString

public static String toString(Object array)

Outputs an array as a String, treating null as an empty array.

参数：

array - the array to get a toString for, may be null

返回：

a String representation of the array, '{}' if null array input

isSameLength

public static boolean isSameLength(Object[] array1,
                                   Object[] array2)

Checks whether two arrays are the same length, treating null arrays as length 0.

Any multi-dimensional aspects of the arrays are ignored.

参数：

array1 - the first array, may be null

array2 - the second array, may be null

返回：

true if length of arrays matches, treating null as an empty array
