本文详细介绍了Java中数组的各种操作方法，包括toString和deepToString方法用于显示数组内容，equals及deepEquals方法用于比较数组是否相等，fill方法用于填充数组元素，以及hashCode和deepHashCode方法的应用。

toString方法：直接输出数组的各个元素的值
[quote]
String[] str1 = {"a","b","c"} ;
System.out.println("str1 values are : "+Arrays.toString(str1));

输出：str1 values are : [a, b, c]

[/quote]
deepToString方法：直接输出多维数组的各个元素的值
[quote]
String[][] str2 = {{"a","aa"},{"b","bb"},{"c","cc"}};
System.out.println("str2 values are: "+Arrays.deepToString(str2));

输出：str2 values are: [[a, aa], [b, bb], [c, cc]]
[/quote]

equals方法：比较两个数组的值是否相等
[quote]
String[] str1 = {"a","b","c"} ;
String[] str2 = {"a","b","c"} ;
if (Arrays.equals(str1, str2))
System.out.println("str1 and str2 are equal.");
else
System.out.println("str1 and str2 are not equal.");

输出：str1 and str2 are equal.
[/quote]

deepEquals方法：比较两个多维数组的值是否相等
[quote]
String[][] str1 = {{"a","aa"},{"b","bb"},{"c","cc"}};
String[][] str2 = str1.clone();

if (Arrays.deepEquals(str1, str2))
System.out.println("str1 and str2 are equal.");
else
System.out.println("str1 and str2 are not equal.");

输出：str1 and str2 are equal.
[/quote]

fill方法：一维数组的填值
[quote]
String[] str1 = new String[2];
Arrays.fill(str1, "{abc}");
System.out.println("str1 values are: "+Arrays.toString(str1));

输出：str1 values are: [{abc}, {abc}]

[/quote]

hashCode，deepHashCode 方法：取得数组的hashCode和deepHashCode值。
sort 方法：对数组元素进行排序
