The current implementation of theStringclass stores characters in achararray, using two bytes (sixteen bits) for each character. Data gathered from many different applications indicates that strings are a major component of heap usage and, moreover, that mostStringobjects contain only Latin-1 char...
更进一步,这里面差不多一半String对象是重复的,重复的意思是说:str1.equals(str2)= true。堆上存在重复的String对象必然是一种内存的浪费。这个项目将在G1垃圾收集器中实现自动持续对重复的String对象进行去重,这样就能避免浪费内存。String 去重的的实现
类似于Lua中的表(table),又称为键值对,属于通过键名与键值存储数据的类型,它的功能非常强大,可以通过键名来获取对应的键值。 按键精灵中表采用json的写法,即使用大括号{}表示范围,使用冒号:表示赋值。 注意,表是无序的,在内部的数据是打乱存放的。 变量赋值table 复制 1234567891011 Dim tt = {"a":1, "b"...

Applications must ignore bits 4 to 15 when reading a version 0 or version 1 table. Versions 0 to 2: The specification for versions 0 to 2 did not specify that bits 0 to 3 must be mutually exclusive. Rather, those specifications stated that, in the event that more than one of bits ...
