Is encapsulation implemented correctly in this code and what are the errors?

Question

Java

class Fox {
    public static void main(String[] args) {
        FoxTest f = new FoxTest();
        f.seta(0);
        f.setb(9);
        f.setc(8);
        f.setd(5);
        int a;
        for(a=1; a<3; a++){
            int b;
        for(b=1; b<3; b++){
                int c;
            for(c=1; c<2; c++){
                    int d;
                for(d=1; d<2; d++){
                  System.out.println("   " + f.geta() + f.getb() + f.getc() + f.getd() /*+ a + b + c + d*/);
                }   
            }
        }   
    }
}
}

class FoxTest {

    private int a;
    void seta(int i) {
        a = i;
    }
    private int b;
    void setb(int i) {
        b = i;
    }
    private int c;
    void setc(int i) {
        c = i;
    }
    private int d;
    void setd(int i) {
        d = i;
    }
    int geta(){
        return a;
        }
    int getb(){
        return b;
        }
    int getc(){
        return c;
        }
    int getd(){
        return d;
    }
}

You have already been told that this code is too primitive. There is no encapsulation here. This class of yours with getters and setters can be thrown out, nothing will change.
