Error When Importing

[Sean Magee]

When I try to import a class it says

  C:\java>javac sean.java  
                  sean.java:1: '.' expected
                   import Person; 
                                        ^            

Does anyone know why?

Hi,


The output

import Person;

Looks very supicious. Does your import statement in your class read

import Person;

?

If you want to import all classes in your package it would look more like

import Person.*;

[Sean Magee]

No, its a class I made myself. I thought I could import is using " import Person; "

You must not import classes in the same package as the current class. If you are using the default nameless package, you must not import any other classes in the default package.
[ref:http://mindprod.com/jgloss/import.html]

if both Person and sean classes are in the same directory, you can use "Person" class in "sean" without importing it.
Also do make the constructor in Person class public, if you want to access it from outside.


public class sean{
Person p = new Person("hi",1);
}

The import command assumes that you are importing a class not in the root(default) package. Thus, there must be a dot in statement. You cannot import from the root package --not that there is a need to anyway; in that case, simply use the class and the JVM will find it.

So, if your Person class is in a package, then you would say

import my.package.Person

Otherwise, there is no need to issue an import statement.

Oh, yeah, I remember that one! The 1.3 parser/compiler we used in Visual Age did not enforce the "no import from current package" rule, but Sun's 1.4 did, so a lot of code that compiled in our system just fine failed in JavaDoc run outside the IDE. Very confusing. You may find old examples and sample code that give you trouble, too.
