Polymorphism in Java refers to the ability of objects of different classes to be treated as if they are of the same class. An example is a superclass Animal with a method makeSound() that is overridden by subclasses Dog and Cat.
You can implement a merge sort algorithm in Java using recursion and a merge method to combine two sorted arrays.
There are two types of exceptions in Java: checked exceptions and unchecked exceptions. Checked exceptions are checked at compile time, while unchecked exceptions are checked at runtime. Examples of checked exceptions include IOException and ClassNotFoundException, while examples of unchecked exceptions include NullPointerException and ArrayIndexOutOfBoundsException.
A HashSet is an unordered collection of unique elements, while a TreeSet is a sorted collection of unique elements.
You can implement a Stack using an Array by maintaining a pointer to the top of the stack and pushing and popping elements from the top of the array.
A shallow copy creates a new object with the same reference as the original object, while a deep copy creates a new object with a new reference.
You can reverse a linked list in Java by iterating through the list and reversing the order of the links between nodes.
A String is immutable, while a StringBuilder and StringBuffer are mutable. StringBuilder is not thread-safe, while StringBuffer is thread-safe.
A binary search tree is a data structure in which each node has at most two children, and the left child is smaller than the parent while the right child is larger. You can implement one in Java using recursion and comparison operators.
