Need some assistance

This is the error I get:
1 error found:
File: C:\JBuilder3\myprojects\PostCardDemo.java [line: 9]
Error: cannot resolve symbol
symbol : constructor PostCard (java.lang.String)
location: class PostCard

My teacher told me I didn't create the class, but I thought I did
'class PostCard'. Do I have to create an additional class? The last
lines of the program are commented out, but I assume that if I fix the
other errors that one will work too.


public class PostCardDemo {
public static void main(String[] args) {
String text = "\tI'm having a wonderful\n" +
"time at Disney World. Weather's\n" +
"great. Wish you were here!";
PostCard p1 = new PostCard("Vanna", text);


PostCard p2 = new PostCard(text);
p2.setRecipient("Merv");
System.out.println(p2.print());
System.out.println(p1.print());

p2.setRecipient("Mom");
p2.print();

PostCard p3 = new PostCard("Sweetie",
"\tI'm miserable without\n" +
"you. It's been raining all week.\n" +
"I can't wait to get back home.");
p3.print();
}

}

class PostCard {
public String recipient;
public String content;

public PostCard(String r, String t) {
recipient = r;
content = t;
content = recipient + content;
}

public String print(){
return content;
}

public String setRecipient(String n){
recipient = n;
return recipient;
}


}

//public String toString(){
//return PostCard("[Dear " + recipient +"]");
//}
