Question

Accepted Answer

Explanation of arrayList, link List, Exception vs RunTime exception, Executors, copy/write array, and Java8 coding question using streams.

ArrayList and LinkedList are both implementations of the List interface in Java. ArrayList uses a dynamic array to store elements, while LinkedList uses a doubly linked list.
Exceptions are checked at compile time, while RuntimeExceptions are unchecked and occur at runtime. Custom classes can throw both types of exceptions.
Executors in Java provide a high-level API for managing threads. They can be used to execute tasks asynchronously.
Copying an array in Java can be done using System.arraycopy() or Arrays.copyOf(). Writing to an array involves assigning values to specific indices.
Java 8 introduced streams for processing collections. They allow for functional-style operations like map, filter, and reduce.
