Question

I let Eclipse generate the equals method for my class and it starts with:

@Override
public boolean equals(Object obj) {
    if (this == obj)
        return true;
    if (getClass() != obj.getClass())
        return false;
[...]

It seems to me, a check like if (obj == null) return false; is missing. Otherwise, if a null reference is passed to equals there will be a null pointer exception in obj.getClass(). Am I wrong or is Eclipse wrong?

Perhaps you are having an old eclipse version. My eclipse generates this:

if (this == obj)
    return true;
if (obj == null)
    return false;
if (getClass() != obj.getClass())
    return false;
