Creating New Student Objects in Java Class

What code segments would successfully create a new Student object based on the given class definition? The code segments 'Student one = new Student(328564, 11);', 'Student two = new Student(238783);', and 'int id = 392349; int grade = 11; Student three = new Student(id, grade);' all succeed in creating new Student objects as they follow the constructors defined in the class. Therefore, the answer is 'E. I, II, and III'.

Creating Objects Using Constructors

When working with classes in Java, creating objects involves using constructors defined within the class. In the provided class definition for Student, there are two constructor types: Student(int s, int g) and Student(int s).

Code Segment Explanation

The code segment 'Student one = new Student(328564, 11);' follows the first constructor type, providing values for both studentID and gradeLevel, and will successfully create a new Student object with the specified values. Similarly, the segment 'Student two = new Student(238783);' follows the second constructor type, providing a value for studentID only, and will create a new Student object with default gradeLevel set to 9.

Lastly, the segment 'int id = 392349; int grade = 11; Student three = new Student(id, grade);' also follows the first constructor type, where both studentID and gradeLevel are provided through variables 'id' and 'grade', resulting in the creation of a new Student object with custom values.

It is crucial to ensure that the inputs provided in the constructor match the parameter requirements set by the constructor to successfully create objects in Java. By adhering to the constructor specifications, new instances of objects can be created to store and manipulate data efficiently within the program.
