I want to show Components in a tabs , so first of all create few components. In this project we have three components, First View Component public class AllViewComponent : ViewComponent { private readonly UserManager<ApplicationUser> _userManager; public AllViewComponent(UserManager<ApplicationUser> userManager) { _userManager = userManager; } public async Task<IViewComponentResult> InvokeAsync() { List<StudentViewModel> allUsers = new List<StudentViewModel>(); var items = await _userManager.Users.ToListAsync(); foreach (var item in items) { allUsers.Add(new StudentViewModel {Id=item.Id, EnrollmentNo = item.EnrollmentNo, FatherName = item.FatherName, Name = item.Name, Age = item.Age, Birthdate = item.Birthdate, Address = item.Address, Gender = item.Gender, Email = item.Email }); }
Data can be of many types e.g. character, integer, real, string etc. Anything enclosed in single quotes represents character data. Numbers without fraction represent integer data. Numbers with fractions represent real data and anything enclosed in double quotes represents a string.
Since the data to be dealt with are of many types, a programming language must provide ways and facilities to handle all types of data. Java, like other languages provide ways and facilities to handle different types of data by providing data types.
Java data types are two types:
The storage size and the range of values supported by numeric integral types are being listed below:
Depending upon your requirement, you can select appropriate data type. Consider this you need to store your phone no 12345678 in your program? What do you think should be the data type? Can you store in a byte or short data type? Well you need to store it in int data type. The reason behind is that the number to be stored does not fall into ranges supported by byte and short types.
One more thing that you must know about data types that all data types are singed i.e., they can store negative as well as positive numbers.

Java data types are two types:
Primitive
Primitive data types we mean fundamental data types offered by Java programming language. Primitive are the basic data type values. The world ‘Primitive’ means a fundamentals component that may be used to create other large parts. Java supports following four categories of primitive data types:- Numeric Integral Primitives types
- Fraction primitive types
- Character primitive types
- Boolean primitive types
Numeric Integral Types
The data types that are used to store numeric values fall under this sub category i.e. numeric primitive data types. Four numeric integral types in Java are Byte, Short, Int and Long. All integral numeric types store integer values i.e. whole numbers only.The storage size and the range of values supported by numeric integral types are being listed below:
- Byte (Size - 8 bits), Byte-length integer having range -128 to + 128.
- Short (Size - 16 bits), Short integer having range -32,768 to + 32,767.
- Int (Size – 32 bits), Integer having range (about) -2 billion to +2 billion.
- Long (Size – 64 bits), Long Integer having range (about) -10E18 to +10E18.
