EqualsBuilder vs own equals method

Question

I just came across a code using EqualsBuilder() in equals method. Is there any advantage of using it instead of writing (or generating from eclipse

Answer 1

Using an EqualsBuilder is not implicitly better or worse than writing your equals method from scratch. In other words, I don't consider using EqualsBuilder to be a best practice.

A non-EqualsBuilder equals() method usually looks like this:

public boolean equals(Object other) {
    boolean result;

    if(this == other)
        result = true;
    else
    if(other == null)
        result = false;
    else
    if(other instanceof MyClass) {
        MyClass o=(MyClass) other;
        result = Objects.equals(this.a, o.a)
                 && Objects.equals(this.b, o.b)
                 // ...
                 && Objects.equals(this.z, o.z);
    }
    else
        result = false;

    return result;
}
