Java Array与Arrays

java.lang.reflect.Array提供了动态创建和访问数组的能力。JDK描述：

 * The {@code Array} class provides static methods to dynamically create and * access Java arrays.

例：

Object a = Array.newInstance(String.class, 3);Array.set(a, 0, "value");String value = (String) Array.get(a, 0);String str[] = (String[])a; 

java.util.Arrays就是提供了对char，byte，short，int，long，float，double，实现了Comparator接口的Object类型的数组的排序、搜索等方法。JDK中这样描述的：

 * This class contains various methods for manipulating arrays (such as * sorting and searching). This class also contains a static factory * that allows arrays to be viewed as lists.
