The following editor will bring you a summary and detailed comparison of several methods of Java collection traversal. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor to take a look at the general traversal method of collection classes, using iterators to iterate: Iterator it = list.iterator();
while(it.hasNext()) {
Object obj = it.next();

4. 10 recommended articles about php next() function
Introduction: The user has multiple business cards and needs to switch left and right to view them. Switching down is the menu button. Here we need to slide in two places. We use the sliding component swiper provided by WeChat and use it in a nested manner. The first layer is the up and down sliding of the business card display and the menu button. The second layer is the left and right sliding of the business card display (supports mutual embedding. It can be used as a set, so you can use it with confidence). Vertical Adding it means sliding vertically, removing it means sliding left and right. The overall structure is as follows: The click event is bound to the data switching method because it needs to support multiple click switching. The initialization data is nextSli...
Introduction: The current() function in php returns the current element (unit, which is the first element of the array) in the array, and the next() function returns the internal The pointer points to the next element in the array and outputs the value of the element. The reset() function points the internal pointer to the first element in the array and outputs the value of the element. This article mainly introduces the current and Next and reset function usage, in the form of examples, the specific usage of the functions current, next and reset for array operations in PHP are described in detail. It has certain reference value for in-depth understanding of the usage of arrays. I hope it will be helpful to everyone's understanding of arrays
6. python iterator and itertools module
Introduction: In python, the iterator protocol implements the __iter() method and next() method of the object, where the former returns the object itself and the latter returns the next element of the container. Objects that implement these two methods are iterable objects. Iterators are lazy and are only generated when used, which provides benefits for processing large amounts of data, unlike writing all data to memory at once. Below I wrote an iterator myself. You can see that you can use a for loop to process the iterator you wrote. For objects that implement the iterator protocol, you can use any iterator tool similar to a for loop. However, looking at the output below, the second output is empty. Why is this? When we use list, we can output the same one multiple times

Introduction: php array: php array php array function sequence next - moves the internal pointer of the array to the position of the next element and returns the element value: next() Definition and usage next() function points to The pointer of the current element moves to the position of the next element and the value of that element is returned. If the internal pointer has passed the last element of the array, the function returns false. Syntax next(array) Parameter Description array Required. Specifies the array to use. Note that next() and current() behave similarly, with one difference: the internal pointer is moved forward one position before returning the value. This means that it returns the value of the next array element and
