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.

4. D

   

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

   generates compilation error because the class is not declared as abstract.

Consider the Java program below.

Choose the correct option regarding the output of the code.

1. A

   This code generates output:

   

2. B

   This code generates output:

   

3. C

   This code generates output:

   

4. D

Consider the following Java code.

Identify the correct option for the code given above.

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

Consider the following Java code.

What will the output be?

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.

   

3. C

   This code generates the output:

   

4. D

   This code generates the output:
