Comparison of Class and Structure in Java
Difference Between Class And Structure In Java
In Java, both classes and structures are used to define custom data types, but they have different characteristics. Classes are reference types and contain both data fields and methods, support inheritance, and are used for complex and larger data structures in object-oriented programming. On the other hand, structures, also known as records in Java, are value types that only contain data fields without methods and do not support inheritance. They are typically used for simple data structures and data transfer objects where immutability and efficient memory usage are desired.

1 - In Java, a class is a blueprint or template for creating objects, while a structure is a user defined data type in C/C++ that groups related data members together.
2) Classes in Java can have constructors, methods, and member variables, while structures in C/C++ only have data members.
3) Java classes support inheritance, encapsulation, and polymorphism, while structures in C/C++ do not have built in support for these features.
4) Classes in Java are reference types, meaning objects of a class are stored in the heap memory, while structures in C/C++ are value types, meaning they are stored in the stack memory.
5) Java classes can have access modifiers like public, private, and protected to control access to their members, while structures in C/C++ do not have such access modifiers.
6) Structures in C/C++ are often used for lightweight data structures with no associated behaviors, while classes in Java are primarily used for building complex objects with behaviors.
7) Java classes can be extended to create sub classes, allowing for hierarchical organization and code reuse, while structures in C/C++ do not support inheritance.
8) Classes in Java can be used to implement abstract data types and object oriented programming paradigms, while structures in C/C++ are typically used for data organization and manipulation.
9) Java classes provide a level of abstraction that structures in C/C++ do not offer, making Java code more maintainable and easier to understand.
10) Overall, classes in Java are more powerful and versatile compared to structures in C/C++ due to the object oriented nature of Java programming language.
