Have you personally implemented the equals object comparison method?

Yes, I implemented the equals method in Java to compare objects by content rather than by reference. This is usually done by overriding the equals method in the class, taking into account all significant fields of the object.

Example implementation:

@Override
public boolean equals(Object obj) {
    if (this == obj) return true;
    if (obj == null || getClass() != obj.getClass()) return false;
    MyClass other = (MyClass) obj;
    return Objects.equals(field1, other.field1) &&
           Objects.equals(field2, other.field2);
}

It is also important to override hashCode when overriding equals to maintain the contract between these methods.
