java tuple

Tuples and list lists, can be used for data storage, with multiple data, but unlike a list: a list can store only the same data type, unlike a tuple, it can store different data types, such as storing int, string, list, and so on, and can be extended indefinitely based on demand. A tuple (Messenger) is a set of objects that are packaged directly and stored in a single object. This container object allows yo

Reprint: Java meta-group type JavatuplesWith respect to the return value of a method, it is often necessary to return a sequence of 2 or more values, such as a record of a data table, a row of files, and so on. In addition to using array arrays, collections (list, set, MAP) of these container types, in Java we have to create a class to be the return type.Tuple-type support is provided in many languages, suc

C # 7.0 has been out for some time, and we all know that there is a tuple optimization in the new feature: ValueTuple. Here's a detailed example of tuple vs ValueTuple (tuple class vs value tuple), 10 minutes to get to know the benefits and usage of ValueTuple.If you know enough about the

One, what is a tuple Tuples are not something new, there are tuples in math, Python language, and C + + that we're talking about today. To put it simply, a tuple is a set of things, for example, when it comes to algebraic topology, the topological space X and one of the dots X are often used as a pair (x, x), which is actually a tuple, and the coordinates of a

First, create a tuple Copy Code code as follows: Tup1 = (' Physics ', ' Chemistry ', 1997, 2000); Tup2 = (1, 2, 3, 4, 5); Tup3 = "A", "B", "C", "D"; Create an empty tuple Copy Code code as follows: Tup1 = (); When you include only one element in a tuple, you need to add a comma after the element to eliminate ambiguity

First, create a tuple Tup1 = (' Physics ', ' Chemistry ', 1997, n); tup2 = (1, 2, 3, 4, 5); tup3 = "A", "B", "C", "D"; Create an empty tuple Tup1 = (); When you include only one element in a tuple, you need to add a comma after the element to disambiguate Tup1 = (50,); Tuples are similar to strings, and subscript indexes start at 0 and can be intercepted, combin

One, tuple is also a class, is immutable list type, can not be deleted. Create: Tup1 = (' Physics ', ' Chemistry ', 1997, 2000);Tup2 = (1, 2, 3, 4, 5);Tup3 = "A", "B", "C", "D"; visit: (same as List) Tup1[1:5]; modification: Can not be modified, can only add new parts; Tup3 = Tup1 + tup2;Print Tup3; Second, any unsigned objects, separated by commas, default to tuples, as follows: a=1,2,3, ' e ' a= (1,2,3, ' e '). The Python

Create a tuple of PythonTuple is another ordered list, and Chinese is translated as "tuple". Tuple and list are very similar, however,once a tuple is created, it cannot be modified. The same is the name of the class, expressed as a tuple as follows:>>> t = (' Adam ', ' Lisa

Python Basics-Basic data type (number (numeric) string (string) list (list) Tuple (tuple) sets (collection) Dictionary (dictionary))There are six standard data types in the Python3:Number (numeric)String (String)List (lists)Tuple (tuple)Sets (collection)Dictionary (dictionary)Among the six standard data types of Python

Tuple is the immutable list. Once you create a tuple, you can't change it in any way. Tuple the same place as the list Defining tuple is the same way as defining a list, except that the entire set of elements is surrounded by parentheses rather than square brackets.The Tuple
