Each entry in the bootstrap_arguments array must be a valid index into the constant_pool table. The constant_pool entry at that index must be a CONSTANT_String_info, CONSTANT_Class_info, CONSTANT_Integer_info, CONSTANT_Long_info, CONSTANT_Float_info, CONSTANT_Double_info, CONSTANT_MethodHandle...
// sort ascending Arrays.sort(integers); // reverse array to obtain it in descending order for (int leftHead = 0, rightHead = integers.length - 1; leftHead < rightHead; leftHead++, rightHead--) { int elem = integers[leftHead]; integers[leftHead] = integers[rightHead]; integers[righ...

int[ ] array = {1,2,3,4,5}; 上面的2种方式都可以实现数组的静态初始化,其中花括号包含数组元素值,元素值之间用逗号“,”分隔。此处注意只有在定义数组的同时执行数组初始化才支持使用简化的静态初始化。为了简便,建议采用第二种方式。 2. 动态初始化 动态初始化是指由程序员在初始化数组时指定数组的长度...

String– The event is a JSON string, including quotes—for example,“My string”. The runtime converts the value into aStringobject without quotes. List<Integer>,List<String>,List<Object>, etc. – The event is a JSON array. The runtime deserializes it into an object of the specified ...
每一种集合类返回的Iterator具体类型可能不同,Array可能返回ArrayIterator,Set可能返回SetIterator, Tree可能返回TreeIterator,但是它们都实现了Iterator接口,因此,客户端不关心到底是哪种Iterator,它只需要获得这个 Iterator接口即可,这就是面向对象的威力。 Iterator源码剖析 ...
