In the below code the Consumer class can access the protected method of Parent class.How is it possible since there is no relation between Parent and Consumer class.Please explain

class Parent {

    public void method1(){
        System.out.println("PUBLIC METHOD");
    }
    private void method2(){
        System.out.println("PRIVATE METHOD");
    }
    protected void method3(){
        System.out.println("PROTECTED METHOD");
    }
    }
    public class Consumer {
    public static void main(String[] args){
        Parent parentObj = new Parent();
        parentObj.method1();
        //parentObj.method2();
        parentObj.method3();
    }
    }

Thanks
