Answer:

a. $_SESSION

Explanation:

A session variable in PHP can be accessed using the global variable $_SESSION.

This can be used for both setting and retrieving session values as described subsequently.

$_SESSION["var1"] = "value1";

This set a session variable called 'var1' to a value 'value1'. Later if we want to retrieve this value we can do it as follows:

echo "Value of session variable 'var1' is " . $_SESSION["var1"] ;

This will print the result: Value of session variable 'var1' is value1

kompoz [17]

Answer:

The code will give an error that is "At least one public class is required in main file".

Explanation:

In the given code if we do not use the public access modifier to the class. It will give an error so, the correct code to this question as follows:

Program:

import java.util.HashSet; //import package

public class A  //define class as public.

{

   public static void main(String[ ] args) //define main method.

   {

       HashSet set = new HashSet(); //creating hashset object.

       set.add("A"); //add alphabet in hashset

       set.add("B"); //add alphabet in hashset

       set.add("C"); //add alphabet in hashset

       System.out.print("Size of HashSet is :"set.size()); //print the size of hashset.

   }

}

Output:

Size of HashSet is : 3

Explanation of the program:  

  • In the above program, we define a public class that is "A" and inside the class, we define the main method.  
  • Inside the main method, we create a HashSet class object that is "set".  
  • To add elements in HashSet we use add() function that adds elements and in the last, we use the size() function that prints the size HashSet.
