Method Detail

equal

public static <T> boolean equal(T arg1,
                                T arg2)

equal

@Deprecated
public static <T> boolean equal(T[] arr1,
                                T[] arr2)

Deprecated. same as Arrays.equals(Object[], Object[])

equal

public static boolean equal(java.lang.CharSequence s1,
                            java.lang.CharSequence s2)

equal

public static boolean equal(java.lang.CharSequence s1,
                            java.lang.CharSequence s2,
                            boolean caseSensitive)

equal

public static boolean equal(java.lang.String arg1,
                            java.lang.String arg2)

equal

public static boolean equal(java.lang.String arg1,
                            java.lang.String arg2,
                            boolean caseSensitive)

strEqual

public static boolean strEqual(java.lang.String arg1,
                               java.lang.String arg2)

Unlike equal(String, String), considers null and "" equal.
