BFS explores neighbors before moving to next level, while DFS explores as far as possible before backtracking.
BFS uses a queue to keep track of nodes to visit next, while DFS uses a stack or recursion.
BFS is optimal for finding shortest path in unweighted graphs, while DFS is more memory efficient.
BFS is typically implemented iteratively, while DFS can be implemented recursively.
Example: BFS is used in level order trav...

Type casting in Java is the process of converting one data type into another.
Type casting can be done implicitly or explicitly in Java.
Implicit type casting is done when a smaller data type is converted to a larger data type, while explicit type casting is done when a larger data type is converted to a smaller data type.
Example of implicit type casting: int num = 10; double result = num;
Example of explicit type casting
Intermediate and terminal operators are used in Java streams to perform intermediate and terminal operations on elements.
Intermediate operators are used to transform, filter, or manipulate elements in a stream before passing them to the next operation. Examples include map(), filter(), and sorted().
Terminal operators are used to trigger the processing of elements in a stream and produce a result. Examples include forEa
Functional interface in Java is an interface with only one abstract method. It can have multiple default or static methods.
Functional interfaces can be annotated with @FunctionalInterface to ensure they have only one abstract method.
Examples of functional interfaces in Java include Runnable, Callable, and ActionListener.
Lambda expressions can be used to implement functional interfaces concisely.
Various methods in RestApi include GET, POST, PUT, DELETE.
GET - Used to retrieve data from the server. Example: GET /users
