Question

Consider the following java class:

class Student {
   private int student_Number;
   private String student_Name;
   public Student(int stNo,String name) {
        student_Number=stNo;
        student_Name=name;
     }
    public String getName() {
      return student_Name;
    }
     public int getNumber() {
      return student_Number;
     }
    public void setName(String st_name) {
      student_Name = st_name;
    }
}

Write a Tester class named StudentTester which contains the following instruction:

1. Use the contractor to create a student object where student_Number =12567, student_Name = “Ali”.
2. Use the setName method to change the name of the student to “Ahmad”
3. Print the student details(i.e., student’s name and student’s number).

Note:

Include the screenshot of the program output as a part of your answer. Otherwise, you will be marked zero for this question.

Answer 1

class Student {
   private int student_Number;
   private String student_Name;
   public Student(int stNo,String name) {
        student_Number=stNo;
        student_Name=name;
     }
    public String getName() {
      return student_Name;
    }
     public int getNumber() {
      return student_Number;
     }
    public void setName(String st_name) {
      student_Name = st_name;
    }
}
//Tester class
class StudentTester
{
    public static void main(String[] args)
    {
        //using constructor to create student object
        Student s=new Student(12567,"Ali");
        //using setName method to change name of student to 'Ahmad'
        s.setName("Ahmad");
        //printing student details
        String name=s.getName();
        int number=s.getNumber();
        System.out.println("Student name:"+name+"\nStudent Number:"+number);
    }
}

Save the above code with name of StudentTester.java

Output
