Question

What will be an ideal response?

Answer 1

```
public class Student
{
private String name;
private String id;
private double gpa;

/** Constructors */
public Student()
{
name = null;
id = null;
gpa = 0.0;
}
public Student(String n, String i, double g)
{
name = n;
id = i;
gpa = g;
}
/** Accessor methods */
public String getName()
{
return name;
}
public String getID()
{
return id;
}
public double getGPA()
{
return gpa;
}

/** Mutator methods */
public void setName(String n)
{
name = n;
}

public void setID(String i)
{
id = i;
}

public void setGPA(double g)
{
if((g >= 0) && (g <= 4))
gpa = g;
}

/** Facilitator methods */
public String toString()
{
return (name + " " + id + " " + gpa);
}
public boolean equals(Student s)
{
return ((name.equalsIgnoreCase(s.name)) && (id.equalsIgnoreCase(s.id)) &&
(s.gpa == gpa));
}
}
```
