Incorrectly overridden methods

Report a typo

Here's a class and its subclass:

class A {
    
    public A method1() { return new A(); }
    
    public B method2() { return new B(); }
    
    public A method3(A a) { return a; } 
    
    public B method4() { return new B(); }
    
}

class B extends A {
    
    @Override
    public B method1() { return new B(); }
    
    @Override
    public B method2() { return new B(); }
    
    public A method3(A a) { return a; } 
    
    public A method4() { return new A(); }
}

Select a method of the class A that is incorrectly overridden in the class B.
