My Class

public class Canetas{

    String modelo;
    String cor;
    double ponta;
    int carga;
    boolean tampada;

    void tampar(){
        this.tampada = true;

    }

    void destampar(){
        this.tampada = false;
    }

    void rabiscar(){
        if (tampada== false){
            System.out.println("A caneta rabiscará...");
        }else{
            System.out.println("Erro!! A caneta não rabiscará...");
        }
        if (carga >= 10){
           System.out.println("A caneta rabiscará..."); 
        }else{
            System.out.println("Erro!! A caneta não rabiscará...");
        }
    }
    void status(){
     System.out.println("_");
     System.out.println("modelo = " + this.modelo );
     System.out.println("cor = " + this.cor );
     System.out.println("ponta= " + this.ponta );
     System.out.println("carga = " + this.carga );
     System.out.println("tampada = " + this.tampada );

    }
}

What did I do wrong I my code?

Answer 1

It would be a lot more easier if you'd write your code in English, not Portuguese. Others would understand your code and what you're trying to do.

Please, have a look at https://docs.oracle.com/javase/7/docs/api/java/util/InputMismatchException.html

It says your input is wrong. E.g. you may enter a float but your expecting an int. Or you enter a string and a number was expected.

I'd suggest reviewing your input lines of codes.
