Java 7's new java.util.Objects class consists of class methods for operating on
objects. These utilities include null-safe or null-tolerant methods for comparing two ob-
jects, computing the hash code of an object, requiring that a reference not be null, and
returning a string for an object.
Table 6-3 describes Objects' class methods.
