Question

Which statement creates a StudentIDs object given the following code: public class StudentIDs> { private TheType item1; private TheType item2; public StudentIDs(TheType i1, TheType i2) { item1 = i1; item2 = i2; } }
a. StudentIDs newStudent = new StudentIDs(9, 5);
b. StudentIDs newStudent = new StudentIDs (Integer iVal1, Integer iVal2);
c. StudentIDs newStudent = new StudentIDs(int iVal1, int iVal2);
d. StudentIDs newStudent = new StudentIDs(9, 5);

Answer 1

Answer:

StudentIDs<TheType> newStudent = new StudentIDs<TheType>(9,5);

Which statement creates a studentIDs object

The question has conflicting details as none of the options is true because some definitions that do not appear in the options.

So, I will answer the question based on the definition in the question.

From the question, we have the class definition to be:

public class StudentIDs<TheType extends Comparable<TheType>>

The above definition is a simple generic java class that follows:

public class Class-Name<Variable-name extends Comparable<Variable-name>>

The object of the class will be created using the following syntax:

Class-Name<TheType> Object-Name = new Class-Name<TheType>();

By comparison:

Class-Name = StudentIDs

Variable-name = TheType

So, the object will be defined as:

StudentIDs<TheType> newStudent = new StudentIDs<TheType>();

Solving further:

The class declares two variables (i1 and i2) as follows:

public StudentIDs(TheType i1, TheType i2)

This means that two TheType variables and/or values will be passed along with the definition of the class.

So, the object definition will be:

StudentIDs<TheType> newStudent = new StudentIDs<TheType>(9,5);
