The explanation of different types of wrapper classes in Java
Wrapper classes in Java are used to encapsulate primitive data types and convert them into objects. They provide a way to treat primitive types as objects, enabling them to be used in scenarios that require objects, such as collections, generics, and methods that expect objects as arguments.
Boolean: This wrapper class is used to encapsulate the
booleanprimitive type. It provides methods for working with boolean values, such as converting strings to booleans and performing logical operations.
Integerclass wraps the
intprimitive type. It provides various methods for converting strings to integers, performing arithmetic operations, and working with integer values.
Floatclass wraps the
floatprimitive type. It offers methods for converting strings to floating-point numbers and performing arithmetic operations.
Character: This wrapper class is used for encapsulating the
charprimitive type. It provides methods for working with individual characters, converting characters to strings, and performing character-related operations.
Byteclass wraps the
byteprimitive type. It is useful for converting strings to bytes and performing byte-related operations.
Longclass wraps the
longprimitive type. It offers methods for converting strings to long integers and performing arithmetic operations with long values.
Short: This wrapper class is used for encapsulating the
shortprimitive type. It provides methods for converting strings to short integers and performing short-related operations.
By using wrapper classes, we can use primitives wherever objects are required and take advantage of the additional functionality provided by the wrapper classes.
