Method Detail

compareBooleans

public static int compareBooleans(boolean one,
                                  boolean two)

true is always greater than false.

compareIntegers

public static int compareIntegers(long one,
                                  long two)

Compare two non-floating point numbers.

compareDoubles

public static int compareDoubles(double one,
                                 double two)

Compare two doubles. Comparisions exist for double and float because casting a float to a double and vice versa can cause loss of precision.

compareFloats

public static int compareFloats(float one,
                                float two)

Compare two floats. Comparisions exist for double and float because casting a float to a double and vice versa can cause loss of precision.

compareStrings

public static int compareStrings(java.lang.String one,
                                 java.lang.String two)

Compare two Strings, null is allowed and is greater than every non-null String.

safeEquals

public static boolean safeEquals(java.lang.Object o1,
                                 java.lang.Object o2)

Equals call that handles null without a NullPointerException.
