TestPrintable.java:14: cannot find symbol

[hoangx87]

I have total of four classes, which are person, shape, printable,testprint.

public class Person implements Printable{

String name;
double weight;



public Person(String n, double w){
name = n;
weight = w;

}

public double getWeight(){
return weight;

}

public double getValue(){
return weight;

}
public String toString(){
return name + "weight" + getWeight();


}

public void print(){

}


}



public class Shape implements Printable{

String color;
double density;
double volume;


public Shape(String c, double d, double v){
color=c;
density=d;
volume=v;

}

public double getWeight(){
return density * volume;

}

public double getValue(){
return getWeight();

}

public String toString(){
return color + "weight" + getWeight();

}
public void print(){

}
}


//has a print method with no params and void return.(DONE!!!)
//Shape and Person should implement Printable (DONE!!!)
// Make class TestPrintable, with method printAll,
//param is array of printable objects. Loop through
//array and call each object print method.
//In main method, make an array of one Shape and one Person,
//and pass to the printall methods.

public interface Printable{

public void print();

}



public class TestPrintable{

public void printALL(Printable[]param){
for (int i=0; i<param.length; i++){

param[i].print();

}

}

public static void main (String[]args){

Printable r =new Shape("joe", 41);
Printable s =new Person("james", 50);
Printable[]param={r,s};

printAll(param);

}

}

I need to know what I have to do to get the program to be error free.
With the following error:


TestPrintable.java:14: cannot find symbol
symbol : constructor Shape(java.lang.String,int)
location: class Shape
Printable r =new Shape("joe", 41);
^
TestPrintable.java:18: cannot find symbol
symbol : method printAll(Printable[])
location: class TestPrintable
printAll(param);
^

Read the error message.

"constructor Shape(java.lang.String,int)"

Does your Shape class have a constructor which takes a String and an int as its parameters?
