It is efficient representation test for arrays。注意,arrays并不是一个高效的set表示方式。如果你要操作的数据量不是一个两个,你应该使用一个真正的Set对象。 includes()方法相较于indexOf()有一个很不同的点。indexOf()执行时的算法和'==='一样。而这个比较算法会将not-a-number的

Returns an array containing all of the elements in this queue, in proper sequence; the runtime type of the returned array is that of the specified array. StringtoString() Returns a string representation of this collection. Methods inherited from class java.util.AbstractQueue ...
So we can use a general representation as shown below. char “stringarrayname” [“number of strings”] [“maximum length of the string”] For example,consider the following declaration: char string_array[10] [20]; The above declaration declares an array of strings named ‘string_array’ wh...

Another popular representation is the null-terminated string, which is essentially an array of bytes terminated by a special sentinel value called the null character. With such a representation, you can create an array of pointers to strings: An array of character strings The array depicted ...

A simple example of metatable for looking up the meta table when it's not available in array is shown below.main.luaOpen Compiler array = { 1, 2, 3, 4, 5, 6 } -- set the metatable setmetatable(array, { -- self represent the table on which metatable is applied -- index is the...
The diagram is just a qualitative representation; quantitative analysis depends on specific situations. Different types of node values occupy different amounts of space, such as int, long, double, and object instances. The memory space occupied by pointer variables depends on the operating system an...
