compilation error java (javac) [closed]

I have a file "poo1.java":

package pootest;

public class init{
        public static void main(String[] args){
                Caneta bic1 = new Caneta();
                bic1.cor = "azul";
                bic1.tampada = true;
                bic1.ponta = 0.5f;
                bic1.carga = 45;
                bic1.modelo = "comun";
                bic1.rabiscar();
        }
}

and another file "pen.java":

package pootest;

class Caneta{
        String modelo;
        String cor;
        float ponta;
        int carga;
        boolean tampada = true;

        void tampar(boolean estado){
                tampada = estado;
        }

        void rabiscar(){
                if (tampada){
                        System.out.print("ta tampada seu jumnet$
                } else{
                        System.out.print("boiolage");
                }
        }
}

When I compile the poo1.java (javac poo1.java) into the terminal this is the output:

  

poo1.java:3: error: class init is public, should be declared in a file   named init.java public class init {          ^ poo1.java:5: error: can not find symbol Pen bic1 = new Pen (); ^ symbol: class Pen location: class init   poo1.java:5: error: can not find symbol Pen bic1 = new Pen ();                           ^ symbol: class Pen location: class init 3 errors
