类名称：Arrays
方法名：deepToString

Arrays.deepToString介绍

[英]Creates a "deep" String representation of the Object[] passed, such that if the array contains other arrays, the String representation of those arrays is generated as well.

If any of the elements are primitive arrays, the generation is delegated to the other toString methods in this class. If any element contains a reference to the original array, then it will be represented as "[...]". If an element is an Object[], then its representation is generated by a recursive call to this method. All other elements are converted via the String#valueOf(Object) method.
[中]创建传递的对象[]的“深”字符串表示形式，这样，如果数组包含其他数组，也会生成这些数组的字符串表示形式。
如果任何元素是基元数组，则生成将委托给此类中的其他toString方法。如果任何元素包含对原始数组的引用，那么它将表示为“[…]”。如果元素是对象[]，则通过递归调用此方法生成其表示形式。所有其他元素都通过字符串#valueOf（Object）方法进行转换。

String[][] deepArray = new String[][] {{"John", "Mary"}, {"Alice", "Bob"}};
System.out.println(Arrays.toString(deepArray));
//output: [[Ljava.lang.String;@106d69c, [Ljava.lang.String;@52e922]
System.out.println(Arrays.deepToString(deepArray));

String[][] x = new String[][] {
  new String[] { "foo", "bar" },
  new String[] { "bazz" }
};
Log.d("this is my deep array", "deep arr: " + Arrays.deepToString(x));
// or
System.out.println("deep arr: " + Arrays.deepToString(x));
// will output: [[foo, bar], [bazz]]
