I am getting the following syntax messages:

illegal start of expression public void display_menu()
(with arrow pointing to the 'p')

and also

';' expected } (with arrow also pointing to the })

This is my code for the first error:

public class InsyStudent extends Student
{

public InsyStudent( String fName, String lName, String ssn )
{

int midTerm;
int finalExam;
int researchProject;
int presentationScore;


public void display_menu()
{
System.out.println( "1) INSY 3305\n2) INSY 3305\n3) INSY 4304");
System.out.println("4) INSY 4305\n5) INSY 4310\n6) INSY 4320\n" );

}

This is my code for the second error:

public String toString()
{
return String.format( "%s %s\t%s", super.toString(), selectCourse() );
}

}

What is the problem?
