Method Detail

areEqual

public static boolean areEqual(boolean aThis,
                               boolean aThat)

Compares two boolean values

Parameters:

aThis - first boolean to be compared

aThat - first boolean to be compared

Returns:

if two boolean are equal

areEqual

public static boolean areEqual(char aThis,
                               char aThat)

Compares two char values

Parameters:

aThis - first char to be compared

aThat - first char to be compared

Returns:

if two chars are equal

                               long aThat)

Compares two long, byte, short or int values

Parameters:

aThis - first value to be compared

aThat - first value to be compared

Returns:

if two values are equal

areEqual

public static boolean areEqual(float aThis,
                               float aThat)

Compares two float values

Parameters:

aThis - first float to be compared

aThat - first float to be compared

Returns:

if two float values are equal

areEqual

public static boolean areEqual(double aThis,
                               double aThat)

Compares two double values

Parameters:

aThis - first double to be compared

aThat - second double to be compared

Returns:

if two values are equal

areEqual

public static boolean areEqual(Object aThis,
                               Object aThat)

Possibly-null object field. Includes type-safe enumerations and collections, but does not include arrays. See class comment.

areEqualWithConstantTiming

public static boolean areEqualWithConstantTiming(String strA,
                                                 String strB)
