Garbage is collected by the garbage collector, part of the system that supports Java programs as they run. The garbage collector runs automatically when needed. In a short program like this it is probably not needed.
Birthday class
Here is a skeleton for the Birthday class:
class Birthday extends
{
private int age;
public ( String r, int years )
{
recipient = r;
age = years;
}
public void greeting()
{
System.out.println("Dear " + recipient + ",");
System.out.println("Happy " + + "th Birthday\n");
}
}
