The identifier main is, under most systems, already in use as an entry point. Even if you're coding a Win32 application, which uses WinMain() as a functional entry point, somewhere along the call path main() will be used.
This means that main cannot be used, even as a variable. It is reserved as an entry point.

What is meant by identifier?
An identifier is the friendly name used by the compiler to represent the location of an object in memory. You could say *0x1234 = *0x3464 + *0x9587, or you could say A = B + C, given that A, B, and C, had those addresses. A, B, and C are identifiers in this example.

What is the difference between variable and identifier?
An identifier is simply the name of something, while a variable is an instance of something.For example:int x;Here, the identifier is "x," but the variable is the object whose name is "x." A: An identifier is a name of something. Typically used in computer programming, the term "identifier" is frequently used to name a variable (see below), a subroutine, are in reality, any place in memory in which data or code reside where a name would be useful. "MyBirthDate" might be a good identifier, pointing to a memory location where the data contianing your date of birth is stored. The term variable comes to us from mathematics, but is frequently used in computer science too. It refers to a value that varies. For instance: a + b = 5 In this case, the value of a and b can change, so long as the sum of a and b equal 5. The opposite of the term variable is constant. In the equation, E=Mc2, c is a constant that is equal to the speed of light in a vacu -- +- 186,000 miles per second. In computer science, the term "variable" is used synonymously with "identifier" when they are both used to point to memory that contains data that may be changed and will not always be the same. In Microsoft BASIC, the statement: Tomorrow = Today + 1 Today and Tomorrow are variables, and 1 is a constant.

What is the similarity between an identifier and a variable?
Answer:- identifier is the name like a, b, c, .... which is used to reference a memory location in a program. +-variable is the actual memory location which can hold values.so 'a' is an identifier to a variable which is memory location located somewhere in memory.Answer:A Variable in Java is something that holds a particular value in a class. For example:public class A { private String name = ""; ......} In the above declaration name is a variable. It would hold the data of type String.An Identifier is nothing but the name that we give for our variables, classes, methods etc. It is nothing but the name with which we identify an entity in Java. For example here A is the identifier for the class, name is the identifier for the variable etc.
