Introduction In Kotlin, IllegalArgumentException is a standard exception that is thrown to indicate that a method has been passed an illegal or inappropriate argument. This exception is part of the Kotlin (and Java) standard library and is used to signal that an argument does not meet the requirements of the method.
Introduction In Kotlin, ConcurrentModificationException is a runtime exception that is thrown when an object is modified concurrently while it is being iterated over. This exception is part of the Kotlin (and Java) standard library and usually occurs when a collection is modified while iterating through it using an iterator, without using the iterator’s remove method.
Introduction In Kotlin, ClassCastException is a runtime exception that is thrown when an attempt is made to cast an object to a type with which it is not compatible. This exception is part of the Kotlin (and Java) standard library and usually indicates a programming error where the cast is not valid.
Introduction In Kotlin, ArithmeticException is a standard exception that is thrown to indicate an exceptional arithmetic condition. This exception is part of the Kotlin (and Java) standard library and typically occurs when an arithmetic operation goes wrong, such as division by zero.
Introduction In Kotlin, Unit is a type that represents the absence of a value. It is similar to void in Java, but in Kotlin, Unit is a real type with a single value, which is Unit. It is used as the return type of functions that do not return a value.
Introduction In Kotlin, the Triple class is used to store three related values. It is a simple data structure that holds a triple of values, which can be of different types. The Triple class is useful when you need to return three values from a function, or when you want to group three related values …
Introduction In Kotlin, the Throwable class is the root of the exception hierarchy. It is used to represent any kind of error or exceptional condition that can occur during the execution of a program. The Throwable class has two main subclasses: Exception and Error. While Exception is used for conditions that a reasonable application might …
Introduction In Kotlin, the String class represents a sequence of characters. Strings are immutable, meaning that once a string is created, it cannot be changed. The String class provides a variety of methods and properties to perform operations on strings, such as manipulation, comparison, and searching.
Introduction In Kotlin, the Short class represents a 16-bit signed integer. It is used for numerical values that require less range than the Int class but more than the Byte class. The Short class provides various methods to perform arithmetic operations, comparisons, and type conversions.
Introduction In Kotlin, the Pair class is used to store two related values. It is a simple data structure that holds a pair of values, which can be of different types. The Pair class is useful when you need to return two values from a function, or when you want to group two related values …
Introduction In Kotlin, an OutOfMemoryError is a runtime error that occurs when the Java Virtual Machine (JVM) cannot allocate an object because it is out of memory, and no more memory could be made available by the garbage collector. This error is critical as it usually indicates that the application is using more memory than …
Introduction In Kotlin, the Number class is an abstract class that serves as the superclass for all numeric types, including Byte, Short, Int, Long, Float, and Double. It provides a common interface for numeric operations and type conversions. The Number class itself cannot be instantiated, but it provides useful methods that are inherited by its …
Introduction In Kotlin, the Nothing class is a special type that represents a value that never exists. It is used to indicate that a function or an expression does not return a value, usually because it always throws an exception or infinitely loops. The Nothing type is a subtype of all other types in Kotlin, …
Introduction In Kotlin, the Long class represents a 64-bit signed integer. It is used for numerical values that require a larger range than the Int class. The Long class provides various methods to perform arithmetic operations, comparisons, and type conversions.
Introduction In Kotlin, the Int class represents a 32-bit signed integer. It is one of the most commonly used data types for numerical values in Kotlin. The Int class provides various methods to perform arithmetic operations, comparisons, and type conversions.
Introduction In Kotlin, the enum class represents a type that consists of a fixed set of constants. Enums are commonly used to represent a collection of related values that are known at compile time, such as days of the week, directions, states, etc. They provide a type-safe way to define and use constants.
Introduction In Kotlin, the Comparator interface is used to define a custom ordering for objects. It is useful when you need to sort objects in a specific way that is not covered by their natural ordering defined by the Comparable interface. The Comparator interface allows you to create custom sorting logic and apply it to …
Introduction In Kotlin, the Comparable interface is used to impose a natural ordering on objects. Classes that implement this interface provide an implementation for the compareTo method, which compares the current object with another object of the same type. This interface is useful for sorting collections and other data structures.
Introduction In Kotlin, the Char class represents a single 16-bit Unicode character. It is used to store and manipulate individual characters. The Char class provides various methods and properties to work with characters effectively.
Introduction In Kotlin, the Byte class represents an 8-bit signed integer. The range of values that a Byte can hold is from -128 to 127. It is commonly used in scenarios where memory optimization is crucial, such as working with binary data or performing low-level programming tasks.
Introduction In Kotlin, Boolean is a class in the Kotlin standard library that represents a boolean value. It can hold one of two values: true or false. The Boolean class provides methods to perform logical operations and is commonly used in control flow statements.
Introduction In Kotlin, AutoCloseable is an interface that ensures resources are closed properly after use. It is typically used in scenarios where you need to manage resources like files, database connections, or network sockets. Implementing AutoCloseable allows you to use the use function, which ensures the resource is closed automatically.
Introduction In Kotlin, ArrayIndexOutOfBoundsException is an exception that occurs when you try to access an index of an array that is outside its valid range. This can happen if you try to access a negative index or an index greater than or equal to the array size.
Introduction In Kotlin, an Array is a collection of elements of a specific type. It is a fixed-size collection, which means once you create an array, you cannot change its size. Arrays are widely used for storing and managing data in Kotlin.
Introduction In Kotlin, Any is the root of the Kotlin class hierarchy. Every Kotlin class has Any as a superclass. It is equivalent to Object in Java but has a more limited set of methods.
