Method Detail

equals

public static boolean equals(Object o1,
             Object o2)

Verification of equivalence of the objects.

Parameters:

o1 - first object.

o2 - second object.

Returns:

true if reference of the objects is equals or internal form of first object equals internal form of second object, false otherwise.
