Question

( Object array + input) Write a Java program to meet the following requirements:
1. Define a class called Student which contains:
1.1 data fields:
a. An integer data field contains student id
b. Two String data fields named firstname and lastname
c. A String data field contains student’s email address
1.2 methods:
a. A no-arg constructor that will create a default student object.
b. A constructor that creates a student with the specified student id, firstname, lastname and email_address
c. A print method that prints student’s student id, firstname, lastname and email address.
2. Write a test class(xxxx_ Program5) which includes a main() method that will take the students’
information from the standard input (keyboard), create and store the information the students’
information in an object array, then print the student information from the object array.
2.1 The data format of user input is
 The first entry is the number of students (numeric)
 The fields below repeat for each student (each field is separated with a space or spaces)
o Student ID (numeric)
o Student first name (String)
o Student last name (String)
o Student email (String)

example:
5
001 st1_firstname st1_lastname [email protected]
002 st2_firstname st2_lastname [email protected]
003 st3_firstname st3_lastname [email protected]
004 st4_firstname st4_lastname [email protected]
005 st5_firstname st5_lastname [email protected]
2.2 The main() method will
(1) Read the first line from keyboard, save this number (numberOfStudents) to a variable.
(2) Based on the number of students, declare an Student Object array to hold the student objects, and the
array size is nubmerOfStudents.
(3) Using loop statements to read the rest of information for each student, create student objects and store the
objects in the Object array you created above.
(Hint: You can use Scanner class, Scanner’s nextInt() method will get integer values, and it’s next()
method will get String values.)
(4) Using loop statements to print out all student objects from the object array.
( Note: If you use the example input above, your output will be like below.)
Students’ information:
001 st1_firstname st1_lastname [email protected]
002 st2_firstname st2_lastname [email protected]
003 st3_firstname st3_lastname [email protected]
004 st4_firstname st4_lastname [email protected]
005 st5_firstname st5_lastname [email protected]
