What is identifier ?

- The name given to class, method, variable and label in java is nothing but the identifier.

Let’s take a below sample example – 

Class Test

{

Public static void main (String args[])

    {

int num = 10;

    }

}

Let’s review - What are the identifiers in above code snippet?

Class Test

{

Public static void main (String args[])

    {

int num = 10;

    }

}

The Test - Class name, main - method name, String - predefined class name, args - variable name & num - variable name are identifiers in above code.
