How to prevent null check before equals

java equals code-cleanup

I find stuff like this rather annoying and ugly in equals methods:

if (field == null)
{
    if (other.field != null)
        return false;
}
else if ( ! field.equals(other.field))
    return false;

In C# I could've done this:

if( ! Object.Equals(field, other.field))
    return false;

Is there something similar in Java, or what is the preferred way to do this kind if thing?
