Question

Arrays enable the representation of a number of similar items (in terms of their datatypes). They represent these items in an ordered list. Consider the features of arrays and respond to the following: In what programming situations would the use of an array be beneficial? What situations would not warrant the use of an array? Provide an example explaining why? Imagine a programming structure that would deal with these problems. What characteristics should the structure possess? Research the concept of class ArrayList in Java. Describe the advantage of using the ArrayList class over an array. Also discuss in what circumstances you should use one over the other. Please use examples to justify your answers.

Answer 1

Check the explanation

Step-by-step explanation:

When there is a need to initialize a lot of element of same data types,tht time we use arrays.

We have to use array whenever it involves simple programs and cases,

dx:saving age of 100 childrans of sametype

When all the ele,ents are of different data type,we hould not use arrays,even when we initialize at runtime,we dont need arrays.i.e when size is not fixed

Linked list can be used instead of arrays

ArrayList:It provides methods for creating, searching, manipulating, and sorting arrays, thereby serving as the base class for all arrays in the common language runtime.

Advantages:

Readymade properties availaible ,so lot of writing and remembering the code can be avoided.

Provide the reference for other arrays

Helps in faster execution
