public class Test {
    static class Parent {
        public <T> Object foo() { System.out.println("Parent"); return null; };
    }

    static class Child extends Parent {
        @Override
        public Object foo() { System.out.println("Child"); return null; };
    }

    public static void main(String[] args) {
        Parent p = new Child();
        p.foo(); // output: Child
    }
}

the above answer is great, just wanted to add a small addendum that technically, one can remove type parameters in the overriding method. i don't have enough reputation to comment so i'm writing here
