Practice Program 2: Create a project named Student that will cont ain two classes: Student and StudentClient Student class Instance variables . Name Social security number Gpa Methods: Constructor that accepts all three instance variables Getters for all three instance variables .Setters for name and social security number .Setter for gpa should only set the value if the value is between 0 and 4.0. toString-Outputs the values of the instance variables in this format: name: Smith; SSN: 333-99-4444 GPA: 3.2 St udent Cdient cl ass: . Create two instances of Student: o Jones, 222-88-1111, 3.7 o Smith, 333-99-4444, 3.2 Write the code to generate the following output: The name of student #1 is Jones The social security number of student #1 is 222-38-1111 The GPA of student #1 is 3.7 Student #2 is name: Smith; SSN: 333-99-4444; GPA: 3.2

Answer 1

Source Code in Java:

public class Student
{
//instance variables
private String name,ssn;
private double gpa;
//parametrized constructor
public Student(String name,String ssn,double gpa)
{
setName(name);
setSSN(ssn);
setGPA(gpa);
}
//getter methods
public String getName()
{
return this.name;
}
public String getSSN()
{
return this.ssn;
}
public double getGPA()
{
return this.gpa;
}
//setter methods
public void setName(String name)
{
this.name=name;
}
public void setSSN(String ssn)
{
this.ssn=ssn;
}
public void setGPA(double gpa)
{
if(gpa>=0 && gpa<=4)
this.gpa=gpa;
}
//method to return a String representation of the object
public String toString()
{
return "name: "+this.name+"; SSN: "+this.ssn+"; GPA: "+this.gpa;
}
}

public class StudentClient
{
public static void main(String args[])
{
//testing the class WebSiteStats
Student s1=new Student("Jones","222-88-1111",3.7);
Student s2=new Student("Smith","333-99-4444",3.2);
System.out.println("The name of student #1 is "+s1.getName());
System.out.println("The SSN of student #1 is "+s1.getSSN());
System.out.println("The GPA of student #1 is "+s1.getGPA());
System.out.println("Student #2 is "+s2);
}
}

Output:

BlueJ: Terminal Window-Code Chef Options The name of student #1 is Jones The SSN。f student #1 is 222-88-1111 The GPA of student #1 is 3.7 Student #2 is name : Smith; SSN : 333-99-4444; GPA: 3.2
