public static boolean isEmpty(String s)
true if the given String is null or empty.
s - the String to check.

String surrounded by single quotes, or null if the given String is
null.
s - the given String.
String surrounded by single quotes, or null if the given String is
null.public static Object quote(Object o)
String.
o - the given object.
String.quote(String)public static String concat(Object... objects)
String. This method is more efficient than concatenating using
"+", since only one StringBuilder is created.
objects - the objects to concatenate.
String containing the given objects.public static Strings.StringsToJoin join(String... strings)
Strings using a given delimiter. The following example illustrates proper usage of this
method:
Strings.join("a", "b", "c").with("|")
which will result in the String "a|b|c".
strings - the Strings to join.
Strings.Strings.StringsToJoin.with(String)public static Strings.StringToAppend append(String toAppend)
String to the given target, only if the target does not end with the given String
to append. The following example illustrates proper usage of this method:
Strings.append("c").to("ab");
Strings.append("c").to("abc");
resulting in the String "abc" for both cases.
