Exceptions are errors that occur during program execution and can be handled using try-catch blocks.
Checked exceptions: must be handled or declared in the method signature
Unchecked exceptions: occur at runtime and do not need to be declared
Error: serious problems that cannot be handled, such as OutOfMemoryError
Examples: NullPointerException, ArrayIndexOutOfBoundsException
Exceptions should be handled gracefully to prevent application crashes.
Use try-catch blocks to catch exceptions.
Handle exceptions at the appropriate level of abstraction.
Log exceptions to aid in debugging.
Provide meaningful error messages to the user.
Avoid catching generic exceptions.
Use finally blocks to release resources.
Consider using custom exceptions for specific error conditions.
To create a custom read-only list, use the ReadOnlyCollection class in C#.
Create a List<T> object with the desired elements.
Use the AsReadOnly() method to create a read-only wrapper around the list.
Use the ReadOnlyCollection<T> class to create a truly read-only list.
Example: List<string> myList = new List<string>{"apple", "banana", "orange"};
Example: var readOnlyList = myList.AsReadOnly();

Collections are data structures that store and manipulate groups of related objects.
Collections are used to store and manipulate groups of related objects
They can be classified into three main categories: Lists, Sets, and Maps
Lists maintain the order of elements and allow duplicates (e.g. ArrayList, LinkedList)
Sets do not allow duplicates and do not maintain order (e.g. HashSet, TreeSet)
Maps store key-value pairs and d...
Binary search is a search algorithm that finds the position of a target value within a sorted array.
The array must be sorted before applying binary search
Compare the target value with the middle element of the array
If the target value is smaller, search the left half of the array
If the target value is larger, search the right half of the array
Repeat until the target value is found or the search space is exhausted
