java.lang.Object
| |||||||||||
Returns 0 if a == b, or c.compare(a, b) otherwise.
That is, this makes c null-safe.
Returns true if both arguments are null,
the result of equals(boolean[], boolean[]) if both arguments are primitive arrays,
the result of deepEquals(Object[], Object[]) if both arguments are arrays of reference types,
and the result of equals(Object) otherwise.
Null-safe equivalent of a.equals(b).
Convenience wrapper for hashCode(), adding varargs.
This can be used to compute a hash code for an object's fields as follows:
Objects.hash(a, b, c).
Returns o if non-null, or throws NullPointerException
with the given detail message.
Returns o if non-null, or throws NullPointerException.
Returns nullString for null or o.toString().
Returns "null" for null or o.toString().
