i have another problem,here's a code i just got from a book;
public class Grade
{
private
String courseName(String name);
public void setCourseName(String name)
{
courseName = name;
}
public String getCourseName()
{
return courseName;
}
public void displayMessage()
{
System.out.printf("Welcome to the grade book for\n%s,getCourseName());
}
public static void main(String args[])
{
Scanner input = new Scanner(System.in);
Grade myGrade = new Grade();
System.out.println("Initial course name was Architecture");
System.out.println();
System.out.println("Please enter the course name:");
String name = input.nextLine();
myGrade.setCourseName(name);
System.out.println();
myGrade.displayMessage();
}
}
setCourseName,considering the fact that it is void which means it shouldnt return any data when it completes task,but in this case i think it does cos the method's being called from the main method(myGrade.setCourseName) and thats when the program prompts you to enter course name after executing.after keying in the course name data is then returned to the system for the line "Welcome to the grade book for ......" to display when the displayMessage is invoked.am i right?
