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 }); }
According to earlier article we have read about literals and some of its types used in Java Programming. We have discussed about the integer literals and floating literals, remaining are in this article.
Following table gives a listing of escape sequences:
In above table, you see sequences representing \, ‘ , “ and ? also. Though these character can be typed from the keyboard but when used without escape sequence, these carry a special meaning and have a special purpose, however, if these are to be typed as it is, then escape sequence should be used.
The following are the example of char literals:
Unicode escape are processed very early and thus must not be represented through \uHn for sequence that have their unique represented escape sequence e.g. \n or \r etc.
“abc” size 6bytes (each character takes 2 bytes)
“\ab” size 4 bytes (\a is one character)
“seema\’s pen” size 22 bytes
(note: \a and \’ are escape sequences)
Boolean Literals
The Boolean type has two values, represented by literals true and false formed from ASCII letters.A Boolean literals is always of type Boolean. It is either Boolean value true or Boolean value false.
Character Literals
A character literal is one character enclosed in single quotes, e.g., ‘z’. The rule for writing character constant is given below:A character literal in Java must contain one character and must be enclosed in single quotation marks.Java allows you to have certain nongraphic characters in character constants. Nongraphic character are those character that cannot be typed directly from keyboard e.g. backspace, tabs, carriage return etc. these nongraphic character can be represented by using escape sequences. An escape sequence is represented by a backslash (\) followed by one or more characters.

In above table, you see sequences representing \, ‘ , “ and ? also. Though these character can be typed from the keyboard but when used without escape sequence, these carry a special meaning and have a special purpose, however, if these are to be typed as it is, then escape sequence should be used.
The following are the example of char literals:
String literals
‘Multiple character’ constants are treated as string literals. The rule for writing string-literals is given below:A string literals is a sequence of zero or more characters surrounded by double quotes. Each character may be represented by an escape sequence.A string literals is of class type String. Following are legal string literals:
“abc” size 6bytes (each character takes 2 bytes)
“\ab” size 4 bytes (\a is one character)
“seema\’s pen” size 22 bytes
(note: \a and \’ are escape sequences)
