An empty array of Objects.

Method Detail

equals

public static final boolean equals(Object o1,
                                   Object o2)

Tests if specified objects are equal using equals(). Unlike with equals(), both objects may be null and two null objects are always considered to be equal.

This function is missing in java.util.Arrays which, on the other hand, has all the other functions: Arrays.equals(boolean[], boolean[]), Arrays.equals(byte[], byte[]), ..., Arrays.equals(Object[], Object[]).

instanceString

public static final String instanceString(Object o)

Returns a string representing specified object. Returns "null" for null.

May be useful when debugging.
