List of Kotlin Exceptions

Exception Name	Explanation
NullPointerException	This exception occurs when you try to access or manipulate an object that is null, meaning it does not reference any instance. It typically happens when you forget to initialize an object or when you incorrectly assume an object is not null.
IllegalArgumentException	This exception is thrown when a method receives an illegal or inappropriate argument. It indicates that the input provided does not meet the requirements or expectations of the method.
IllegalStateException	This exception signals that the state of an object is not suitable for the operation being performed. It usually occurs when a method is called but the object is not in the correct state to execute that particular operation.
IndexOutOfBoundsException	This exception occurs when you try to access an array, list, or string using an index that is either negative or greater than or equal to the size of the collection. It indicates that the index is outside the valid range of values.
ClassCastException	This exception is thrown when you attempt to cast an object to a type that is not compatible. It occurs when there is a fundamental type mismatch during the casting operation.
NoSuchElementException	This exception is raised when you try to access an element from a collection such as a list or a set, but the collection is empty, and no element exists at the requested position.
UnsupportedOperationException	This exception is thrown when an operation is not supported by the current implementation or when an object is in an immutable state, and a modification operation is attempted on it.
ConcurrentModificationException	This exception indicates that a concurrent modification was detected while iterating over a collection using an iterator. It happens when the structure of the collection is modified (such as adding or removing elements) during iteration.
NumberFormatException	This exception occurs when you try to convert a string to a numeric type (such as an integer or a float), but the string has an invalid format that cannot be parsed as a number.
ArithmeticException	This exception is raised when an arithmetic operation (such as division or modulo) fails due to exceptional conditions, such as dividing by zero or an integer overflow/underflow.
ArrayIndexOutOfBoundsException	This exception is thrown when you try to access an array element using an index that is outside the valid range of indexes for the array. It indicates that the index is either negative or greater than or equal to the array’s length.
SecurityException	This exception is thrown when a security violation is detected. It occurs when a Java security manager denies a requested operation or when a security-related error occurs during runtime.
InterruptedException	This exception is raised when a thread is waiting, sleeping, or occupied with another blocking operation, and it gets interrupted by another thread. It is typically used for thread synchronization and coordination.
OutOfMemoryError	This error indicates that the Java Virtual Machine (JVM) has run out of memory. It occurs when there is insufficient memory available to allocate new objects or when the heap space is exhausted.
StackOverflowError	This error occurs when the stack size allocated for a program’s execution is exhausted. It usually happens when a method calls itself recursively without a proper termination condition, causing an infinite recursion.
FileNotFoundException	This exception is thrown when an attempt to access a file or directory fails because the specified file or directory does not exist. It indicates that the requested resource could not be found on the file system.
IOException	This exception is the superclass for a wide range of I/O-related exceptions. It is thrown when an I/O error occurs during reading from or writing to a file, socket, or any other input/output operation.
MalformedURLException	This exception is thrown when an invalid or malformed URL is encountered. It indicates that the provided URL string is not well-formed and does not conform to the expected format of a URL.
SocketException	This exception is raised when an error occurs during socket-related operations, such as opening, closing, or reading from/writing to a socket. It indicates a problem with the underlying network communication.
ParseException	This exception is typically used in parsing operations, such as parsing dates or parsing strings in a specific format. It occurs when the input string does not conform to the expected format or cannot be parsed correctly.
SQLSyntaxErrorException	This exception is specific to database operations. It is thrown when an SQL statement is executed, but the syntax of the statement is invalid or incorrect, preventing its successful execution by the database engine.

DateTimeException	This exception is used in date and time operations when there is an error or inconsistency in the provided date, time, or datetime value. It occurs when there is an invalid combination of date or time fields.
JsonParseException	This exception is raised when an error occurs while parsing JSON data. It typically indicates that the provided JSON string is not well-formed or does not conform to the expected JSON syntax.
SocketTimeoutException	This exception is thrown when a socket operation times out because it took too long to complete. It occurs when a connection or communication through a socket exceeds the specified timeout value.
NoSuchFileException	This exception is specific to file operations. It is thrown when an attempt is made to access a file that does not exist or cannot be found at the specified path.
DateTimeParseException	This exception is thrown when there is an error during the parsing of date, time, or datetime strings. It occurs when the input string cannot be parsed according to the specified format or does not represent a valid date/time.

NoSuchMethodException	This exception is raised when a particular method is not found in a class or when you attempt to access a method that does not exist. It indicates that the requested method could not be found at runtime.
IllegalAccessException	This exception is thrown when there is a violation of the access control rules while attempting to access a field or invoke a method. It typically happens when you try to access a private or protected member from outside its scope.
AssertionError	This exception is thrown when an assertion check fails. It occurs when an assert statement evaluates to false, indicating that an assumption made by the programmer is incorrect or violated.

InputMismatchException	This exception is specific to input operations. It is thrown by a scanner when the input does not match the expected data type or format. It indicates that the input provided does not match the expected input pattern.

NoSuchAlgorithmException	This exception is raised when a cryptographic algorithm is requested, but the specified algorithm is not available or supported by the Java Virtual Machine (JVM) or the underlying security provider.
ArrayStoreException	This exception is thrown when an attempt is made to store an object of an incompatible type into an array. It indicates that the object being stored cannot be assigned to the array’s component type.
IllegalThreadStateException	This exception occurs when an operation is attempted on a thread, but the thread is in an illegal or inappropriate state for that operation. It typically happens when you try to start a thread that is already running or has terminated.
