cannot find symbol - compiler error?

[Anuradha Prasanna]

I have a java pgm, "test.java" in "C:\MyProjects\beerV1" folder

public class test{

public static void main(String[] args){
new BeerExpert(); //line1
System.out.println("test beerV1");
}
}

and the "BeerExpert.class" file in "C:\MyProjects\beerV1\classes\com\example\model" folder

which contains,

package com.example.model;

import java.util.*;

public class BeerExpert {

public List<String> getBrands(String color) {
List<String>  brands = new ArrayList<String>();
if(color.equals("amber")) {
brands.add("Jack Amber");
brands.add("Red Moose");
}
else{
brands.add("Jail Pale Ale");
brands.add("Gout Stout");
}
return brands;
}
}

so when i try compiling the "test.java" as below i get the, "cannot find symbol" error as below,

C:\MyProjects\beerV1>javac -cp classes test.java
test.java:4: cannot find symbol
symbol : class BeerExpert
location: class test
new BeerExpert();

1 error

can anyone please tell me how to compile the "test.java" file, which uses the "BeerExpert.class" file?

you just need an import statement

  
import com.example.model.BeerExpert;

public class test{

public static void main(String[] args){
new BeerExpert(); //line1
System.out.println("test beerV1");
}
}

If don't import the class, how java knows where the class situated? public access modifier and import package are two different strories!

If you don't import the class, then you'll have to use the fully qualified name of the class everywhere. So test.java would look like

public class test{
    public static void main(String[] args){
        new com.example.model.BeerExpert(); //line1
        System.out.println("test beerV1");
    }
}

Import is just an easy way of using a class in a package so that you don't have to use the fully qualified name of the class everywhere. The compiler and JVM both look for classes on the classpath...
