And earth lives in buildings that look like terraced farms or flowering plants. Water lives in tall, glass buildings in floating apartments that resemble Galileo thermometers. The lead character, Ember, lives in Fire Town, where buildings are made of inflammable materials or ones that are even made by fire, like ceramics, terracotta, and metal. During the press day, production designer Don Shank discussed some of the real-world physics that had to be worked out in order to create a physical space where living elements could live. Like Lucasfilm’s “Immaculate Reality” principal, Pixar’s own “Truth in Materials” philosophy had to be applied. As the city prospered, it attracted a community of fire, but the city wasn’t really built with fire in mind. The city was founded by water and earth, who came together to create a delta that would also attract air. Using ArrayList.remove() method is the fastest way for removing an element from the ArrayList.The history of Element City isn’t presented in the film, but just like a planet in Star Wars, Pixar created one for the story. ("\nAfter removing the element the size of the ArrayList is: " cities.size()) Īll of the above-discussed methods are used for different scenarios. Removing elements which are start with B using removeIf() methodĬities.removeIf(n -> (n.charAt(0) = 'B')) ("The list of the size is: " cities.size()) Let's take an example to understand how the removeIf() method is used. We pass the predicate filter to that method as an argument. If we want to remove an element from the ArrayList which satisfy the predicate filter, the removeIf() method is best suited for this case. ("\nAfter removing the element the size of the ArrayList is: " numbers.size()) Removing elements greater than 10 using remove() method ("The list of the size is: " numbers.size()) creating an ArrayList having default size 10 Let's take an example to understand how the Iterator.remove() method is used. The Iterator class removes elements properly while iterating the ArrayList. When we use the remove() method while iterating the elements, it throws the ConcurrentModificationException. It is not so helpful in case when iterating over elements. The Iterator.remove() method is another way of removing an element from an ArrayList. ("\nAfter removing the element the size of the ArrayList is: " arr.size()) Removing the specified element from ArrayList Showing all the elements in the ArrayList ("The list of the size is: " arr.size()) creating an ArrayList having default size 5 Let's take an example to understand how the remove() method is used. The remove(int index) method accepts the index of the object to be removed, and the remove(Object obj) method accepts the object to be removed. It also provides the two overloaded methods, i.e., remove(int index) and remove(Object obj). Using the remove() method of the ArrayList class is the fastest way of deleting or removing the element from the ArrayList. Let's understand all these three ways, one by one. However, there is more than one way of removing an element from the ArrayList that are as follows:Īll these three ways are best in their own, and can be used in some different scenario. Adding and removing an element from the ArrayList is very easy by using its built-in methods add() and remove(). The ArrayList class is available in the Java.util package and extends the List interface.
