Hi class,
A data structure is a set of elements that helps one to manipulate data. The size of a static data structure is set. As the need for storage grows, a dynamic data structure may expand and contract.
ArrayList This sort of list is implemented as an array that is dynamically sized, that is if the list’s size needs to be increased by 50%. If you have a ten-item list, an add operation would automatically raise the size to fifteen. The ArrayList also allows elements to be accessed directly using the get () and set () methods, as well as added and removed using the add () and remove () methods (). Duplicate elements are not removed by ArrayList.
LinkedList The output of the methods add, delete, get, and set is the key difference between LinkedList and ArrayList.
This type of list performs better in the add and remove methods than the ArrayList’s add and remove methods, but its get and set methods perform worse than the ArrayList’s get and set methods.
Vector Vectors are very similar, to the point of being identical. If you are unfamiliar with the concepts of Vector and ArrayList, they are used interchangeably. The Vector multiplies by two, so if you have a complete list of ten elements, the list would expand to twenty, with ten empty places.
