difference between arrayList and LinkedList in java
Sure! An ArrayList is like a list of items in a line, where each item has a number. You can add or remove items from the list, but it takes more time to do so if you want to add or remove an item in the middle of the list. This is because all the items after the new item need to be moved to make space. A LinkedList is like a chain of items, where each item is connected to the next item. You can easily add or remove items from the middle of the list because you only need to change the connections between items, not move the items themselves. One verifiable fact is that ArrayList is faster for accessing items in the list, while LinkedList is faster for adding or removing items in the middle of the list. For example, let’s say you have a list of friends: ArrayList: [Alice, Bob, Carol, David] If you want to add a new friend, Emily, between Bob and Carol, you would have to move Carol and David to make space: ArrayList: [Alice, Bob, Emily, Carol, David] LinkedList: [Alice] -> [Bob] -> [Carol] -> [David] If you wanted to add a new friend, Emily, between Bob and Carol in a LinkedList, you would just need to change the connections: LinkedList: [Alice] -> [Bob] -> [Emily] -> [Carol] -> [David] I hope this helps you understand the difference between ArrayList and LinkedList in Java!
