I need to write a class that encapsulates this program. It should supplement the constructor, accessors, and mutators. As well as methods like toString and equals.

public class StudentClient
{
public static void main( String [] args )
{
    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 social security number of student #1 is \" + s1.getSsn( ) );
    System.out.println( \"The gpa of student #1 is \" + s1.getGpa( ) );
    System.out.println( \"Student #2 is \" + s2.toString( ) );

    if ( s1.equals( s2 ) )
      System.out.println( \"Original students #1 and #2 are identical\" );
    else
      System.out.println( \"Original students #1 and #2 are different\" );

    s2.setName( \"Jones\" );
    s2.setSsn( \"222-88-1111\" );
    s2.setGpa( 3.7 );

    if ( s1.equals( s2 ) )
      System.out.println( \"Original student #1 and modified student #2 are identical\" );
    else
      System.out.println( \"Original student #1 and modified student #2 are different\" );

}
}

Solution

Student.java


public class Student {
   private String name;
   private String ssn;
   private double gpa;
   public Student(String n, String s, double g){
       name = n;
       gpa = g;
       ssn = s;
   }
   public String getName() {
       return name;
   }
   public void setName(String name) {
       this.name = name;
   }
   public String getSsn() {
       return ssn;
   }
   public void setSsn(String ssn) {
       this.ssn = ssn;
   }
   public double getGpa() {
       return gpa;
   }
   public void setGpa(double gpa) {
       this.gpa = gpa;
   }
   public String toString(){
       return \"name is \"+name+\" ssn is \"+ssn+\" gpa is \"+gpa;
   }
   public boolean equals(Student s){
       if(this.name == s.name && this.ssn == s.ssn){
           return true;
       }
       else{
           return false;
       }
   }
}

StudentClient.java

public class StudentClient
{
public static void main( String [] args )
{
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 social security number of student #1 is \" + s1.getSsn( ) );
System.out.println( \"The gpa of student #1 is \" + s1.getGpa( ) );
System.out.println( \"Student #2 is \" + s2.toString( ) );
if ( s1.equals( s2 ) )
System.out.println( \"Original students #1 and #2 are identical\" );
else
System.out.println( \"Original students #1 and #2 are different\" );
s2.setName( \"Jones\" );
s2.setSsn( \"222-88-1111\" );
s2.setGpa( 3.7 );
if ( s1.equals( s2 ) )
System.out.println( \"Original student #1 and modified student #2 are identical\" );
else
System.out.println( \"Original student #1 and modified student #2 are different\" );
}
}

Output:

The name of student #1 is Jones
The social security number of student #1 is 222-88-1111
The gpa of student #1 is 3.7
Student #2 is name is Smith ssn is 333-99-4444 gpa is 3.2
Original students #1 and #2 are different
Original student #1 and modified student #2 are identical
