@Override public boolean equals(Object o) “Method does not override and superclass method”

Question

Theoretically this is a really simple (dumb) question...

Compiles successfully:

@Override
public int hashCode() {return 0;}

Error: "Method does not override any superclass method"

@Override
public boolean equals(Object obj) {return true;}

It seems to me that if my override of hashCode() compiles the override of equals() should also compile... Obviously I don't understand something relatively fundamental...

What should I look for to resolve this compiler error?

Answer 1

My project had a class within the same package as the class exhibiting the compilations issue... this obscured the Java's base Object class (and its equals() method).

Here's the corrected code:

@Override
public boolean equals(java.lang.Object obj)
{
    return true;
}
