Method Detail

equalObjects

public static boolean equalObjects(Object object1,
                                   Object object2)

Indicates whether the given objects are "equal to" each other.

This method should be used in place of the Object.equals if one ore both arguments can be null.

If both objects are arrays of the same primitive types the comparision is delegated to the corresponding java.util.Arrays.equals method.

If both objects are object arrays with equal lengths, the method is recursively called for each array element pair. If the first pair is not equal, the method immediately returns false.

Parameters:

object1 - the first object, can be null

object2 - the second object, can also be null

Returns:

true if this first object equals the second; false otherwise.
