equal

@Contract(value="null,!null -> false; !null,null -> false; null,null -> true",
          pure=true)
public static <T> boolean equal(@Nullable
 T arg1,
 @Nullable
 T arg2)

equal

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

已过时。

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

Use Objects.equals(Object, Object)

equal

@Contract(value="null,!null,_ -> false; !null,null,_ -> false; null,null,_ -> true",
          pure=true)
public static boolean equal(@Nullable
 @Nullable String arg1,
 @Nullable
 @Nullable String arg2,
 boolean caseSensitive)

strEqual

public static boolean strEqual(@Nullable
 @Nullable String arg1,
 @Nullable
 @Nullable String arg2)

Unlike Objects.equals(Object, Object), considers null and "" equal.

strEqual

public static boolean strEqual(@Nullable
 @Nullable String arg1,
 @Nullable
 @Nullable String arg2,
 boolean caseSensitive)

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

haveEqualElements

 @NotNull Collection<? extends T> a,
 @NotNull
 @NotNull Collection<? extends T> b)

haveEqualElements

public static <T> boolean haveEqualElements(@Nullable

 @Nullable
 @Nullable T[] b)

hashcode

public static int hashcode(@Nullable
 @Nullable Object obj)

hashcode

public static int hashcode(Object obj1,
 Object obj2)

unorderedHashcode
