Answer 1

public class student {
   private int id;
   private int age;
   private double gpa;
   private int creditHours;
  
   //default constructor
   public student() {
   }
  
   //parameterized constructor
   public student(int id, int age, double gpa, int creditHours) {
       super();
       this.id = id;
       this.age = age;
       this.gpa = gpa;
       this.creditHours = creditHours;
   }
   //getters and setters
   public int getId() {
       return id;
   }
   public void setId(int id) {
       this.id = id;
   }
   public int getAge() {
       return age;
   }
   public void setAge(int age) {
       this.age = age;
   }
   public double getGpa() {
       return gpa;
   }
   public void setGpa(double gpa) {
       this.gpa = gpa;
   }
   public int getCreditHours() {
       return creditHours;
   }
   public void setCreditHours(int creditHours) {
       this.creditHours = creditHours;
   }
  
   public static void main(String[] args) {
       // a simple main to show functioning of getter and setter
       student s = new student(1, 12, 7.8, 12);
       System.out.println(s.getAge());
       s.setAge(13);
       System.out.println(s.getAge());
   }

}
