    Primitive Values, Wrapper Classes, Types And Casting

    This section explores Java's primitive data types, wrapper classes, and type conversion mechanisms, essential for effective programming.

    Learning Practice

  • 6.1

    Introduction

    Java data types are essential for programming, consisting of primitive and reference types with wrapper classes for object-oriented functionality.

    Learning Practice

  • 6.2

    Primitive Data Types In Java

    This section explores Java's primitive data types, their characteristics, and the importance of wrapper classes for manipulating these types as objects.

    Learning Practice

  • 6.3

    Wrapper Classes

    Wrapper classes in Java enable primitive data types to be treated as objects, facilitating various operations, particularly with collections.

    Learning Practice

  • 6.4

    Autoboxing And Unboxing

    Autoboxing and unboxing in Java allows automatic conversion between primitive types and their corresponding wrapper classes.

    Learning Practice

  • 6.5

    Type Conversion And Casting

    This section explores type conversion and casting in Java, including both implicit and explicit conversions, highlighting the roles of primitive data types and wrapper classes.

    Learning Practice

  • 6.5.1

    Implicit Type Conversion (Widening Conversion)

    This section explores implicit type conversion in Java, focused on widening conversion, where smaller data types are automatically converted to larger data types.

    Learning Practice

  • 6.5.2

    Explicit Type Conversion (Narrowing Conversion)

    Explicit type conversion in Java involves manually converting a larger data type into a smaller one, often requiring truncation of data.

    Learning Practice

  • 6.6

    Wrapper Class Methods

    This section covers wrapper class methods in Java, which allow primitive types to be treated as objects and enable operations such as parsing and converting values.

    Learning Practice

  • 6.7

    Example Program

    This section illustrates the use of Java’s primitive types and their corresponding wrapper classes through an example program.

    Learning Practice

  • 6.8

    Summary

    Java provides eight primitive data types and wrapper classes for effective data manipulation.
