Select all that apply.

1. A

   An activation record is removed from the stack immediately after a local variable is declared.

2. B

   Local variables of a function are typically stored inside its activation record.

3. C

   A return address is stored in the activation record so that control can return to the caller after the execution of the called function.

4. D

   All activation records in the stack correspond only to recursive function calls.

5. E

   When a function calls another function, the control link in the callee's activation record points to the activation record of the caller.

Consider the Java code given below.

Which of the following statements is FALSE?

1. A

   generates compilation error because the method cannot be overridden.

2. B

   generates compilation error because variable cannot be accessed in class .

4. D

   generates compilation error because a variable of type cannot refer to an object of type .

Consider the Java code given below.

Choose the correct option.

1. A

   This code generates output:

   

2. B

   This code generates output:

   

3. C

   This code generates a compile time error, since the implementations of from and are in conflict with each other.

4. D

   This code generates a compile time error since is not implemented in class

2. B

   

3. C

   

4. D

   

Consider the Java code given below.

Choose the correct option.

1. A

   This program generates compiler error at Reason: An object of cannot be created inside method because it uses an object of in its constructor.

2. B

   This program generates the output: followed by runtime error Reason: A method inside class is invoking method inside class , whereas is invoking another method in class .

   

3. C

   This program generates compiler error at Reason: A method inside class is invoking method inside class , whereas is invoking another method in class .

4. D

   This program generates the output:

   

Consider the code given below.

Choose the correct option.

1. A

   generates compilation error because a variable of type cannot refer to an object of type .

2. B

   This code generates the below output followed by runtime error at because there is ambiguity in which method is being invoked.
