A detailed introduction to next ()

The following small series for everyone to bring a summary of several ways of Java collection traversal and detailed comparison. Small series feel very good, now share to everyone, also for everyone to make a reference. Let's see it together. General traversal of the collection class, iterative with iterators: Iterator it = List.iterator (); while (It.hasnext ()) {Object obj = It.next ();} Map Traversal mode: 1, by obtaining all keys to follow the key to traverse//set<integer> Set = Map.keyset (); Get the set for all keys for (Integer In:map.keySet ()) {String Str&a

3. PHP operation Array function current, Next and reset function usage examples

Summary: The current () function in PHP is the return element in the array (cell, the first element of the array, the next () function is to point the inner pointer to the next element in the array, and output the value of the element. The reset () function is to point the inner pointer to the first element in the array and output the value of the element. This article mainly introduces the use of current, next and reset functions in PHP, and describes in detail the specific usage of the current, next, and reset functions for array manipulation in PHP in the form of an instance, which has a certain reference value for in-depth understanding of the use of arrays. I hope it helps to understand the array.

4. Python iterators and Itertools modules

Summary: In Python, the iterator protocol is the __iter () method of the implementation object and the next () method, where the former returns the object itself, which returns the next element of the container. The object that implements both methods is an iterative object. Iterators are inert and only occur when used, which provides the benefit of processing large amounts of data, and writes all data to memory at once. By writing an iterator yourself, you can see that using a For loop can handle an iterator that you have written, implements an iterator protocol object, and can use any iterator tool similar to a for loop. But, looking at the output below, the second output is empty, which is why? When we use list, we can output the same one multiple times.

6. PHP array php Array function sequence Next-Move the array interior pointer to the position of the next element, and return the element value

Introduction: PHP Array: PHP array php Array function sequence Next-Move the array inside the pointer to the position of the next element, and return the element value: Next () define and use the next () function moves the pointer to the current element to the position of the next element, and returns the value of the element. If the internal pointer already exceeds the last element of the array, the function returns FALSE. The syntax next (array) parameter describes the array required. Specifies the array to use. Note that next () and current () behave similarly, with only a little difference, moving the internal pointer forward one bit before the return value. This means that it returns the value of the next array cell and
