Method Detail

equals

public static boolean equals(Object o1,
             Object o2)

Compares two objects for equality.

Parameters:

o1 - Object

o2 - Object

Returns:

whether o1 and o2 are equal

equals

public static boolean equals(Object[] o1,
             Object[] o2)

Compares two arrays of objects for equality.

Parameters:

o1 - Object array

o2 - Object array

Returns:

whether o1 and o2 are equal

equals

public static boolean equals(byte[] o1,
             byte[] o2)

Compares two byte arrays for equality.

Parameters:

o1 - byte array

o2 - byte array

Returns:

whether o1 and o2 are equal

equals

public static boolean equals(int[] o1,
             int[] o2)

Compares two int arrays for equality.

Parameters:

o1 - int array

o2 - int array

Returns:

whether o1 and o2 are equal

compare

public static <T> int compare(Comparable<T> c1,
              T c2)

Compares two objects for relative order. Null values are ordered before (ie. considered smaller than) non-null values.

Type Parameters:

T - type of objects.

Parameters:

c1 - Object that implements Comparable

c2 - Object

Returns:

-1, 0, or 1 depending if c1 is less than, equal, or greater than c2.
