Given the class hierarchy below. Could the symmetry of equals() be violated? If yes, provide client code that demonstrates that. class A { int x; public A(int x) {this.x = x;} public boolean equals(Object o) { if (!(o instanceof A)) return false; A a = (A)o; return this.x == a.x; } } class B extends A { int y; public B(int x, int y) {super(x); this.y = y;} }
