What methods should go into a java.util.Objects class in JDK 7?

[Paul Benedict]

If you want Objects.toString() to provide value, consider mimicking
the functionality from Apache Commons:

http://commons.apache.org/lang/api-2.4/org/apache/commons/lang/ObjectUtils.html

My biggest complaint about String.valueOf(Object) is that it will
actually return "null" for null objects. I can't stand that. If I have
no data, I don't want any printable data back. While my preference
might be too narrow for the JDK, the second overloaded version of
ObjectUtils#toString(String, String) seems like a winner to me. Allow
a default String to be provided when it is null:

public static String toString(Object o, String defaultStr) {
    return (o != null) ? : String.valueOf(o) : defaultStr;
}
