Problem Statement:

Write a program in java that will have two classes i.e. Student and Test. Student class will have three attributes (id, name and program) and methods of constructors, getters, setters and print etc. Test class will have the main method in which you are required to create four objects of Student class and store them in an array. You have to write code for error exception handling as well in case if the array index is to be accessed out of bound.

Detail:

• Student class will have three attributes (id, name and program).
• Methods of Constructors i.e default and parameterized to initialize the attribute.

1. Default constructors: If an object of Student class is created without passing any parameter default constructor should be executed and set the values of attributes (id, name, and program) to your own student id, name and program.

2. Parameterized Constructors: When parameters are provided then parameterized constructor will initialize the data members with the given values.

• If the first two characters of the program string for example BS does not match the first two characters of Student id i. e BC457810241 then error should displayed as:

“Your program does not match your student Id”

• It should have getter and setter functions to get or set the values of any one attribute.
• print function of Student class should display the students object data store in the array list.
• Test class will have the main method in which you are required to create four objects of Student class and store them in an Array. 
• First object should be without providing the parameters so it should call the default constructor.
• Display the data of all the four students using for loop with one more index i.e 0,1,2,3,4. On index 4, the Index out of Bounds Exception should be displayed.

SOLUTION

STUDENT:

//public class Student ()

public class Student {

    

    private String id;

    private String name;

    private String program;

    

   // default constructor

    

    public Student () {

    id = "BSc00000000";

name = "Ahmed";

program = "BSc Computer Science";

    }

   

    // parameters constructor

    public Student (String id, String name, String program) {

        this.id = id;

        this.name = name;

        this.program =program;

        if(id.substring(0,2).equals(program.substring(0,2)) ) {

            this.program = program;

        }

        else {

            this.program = "Your Program does not match your student Id";

        }

}

public String getId() {

    return id;

}

public void setId(String id) {

    this.id = id;

}

public String getName() {

    return name;

}

public void setName(String name) {

    this.name = name;

}

public String getProgram() {

    return program;

}

public void setProgram(String program) {

    this.program = program;

}

// print function

public void print (Student student) {

    System. out.println("Id: " + student.getId() + "Name : " + student.getName() +"program: " + student.getProgram());

}

}

Test:

public class Test {

    public static void main (String[] args) {

        Student object[]  = new Student [4];

        object[0] = new Student();

        object[1] = new Student ("BS0000001", "Ahmed Ali", "ВSc Computer Science");

        object[2] = new Student ("BC0000003", "Ali Noor", "BS IT");

        object[3] = new Student ("BS0000002", "Asif", "MS Computer Science");

          

        for (int i = 0; i < 4; i++) {

        

            try {

                Student student = new Student();

                student.print (object[I]);

            }

            catch (ArrayIndexOutOfBoundsException e) {

                e.printStackTrace();

            }

        }

    }

}
