default boolean	matchesAllOf(CharSequence sequence)	Returns true if a character sequence contains only matching BMP characters.
default boolean	matchesAnyOf(CharSequence sequence)	Returns true if a character sequence contains at least one matching BMP character.
default boolean	matchesNoneOf(CharSequence sequence)	Returns true if a character sequence contains no matching BMP characters.
static CharPredicate	noneOf(String chars)	Returns a CharPredicate that matches any of chars.
default CharPredicate	not()	Returns the negation of this CharPredicate.
default CharPredicate	or(char ch)	Returns a CharPredicate that evaluates true if either this predicate evaluates to true, or the character is ch.
default CharPredicate	or(CharPredicate that)	Returns a CharPredicate that evaluates true if either this or that predicate evaluate to true.
default CharPredicate	orRange(char from, char to)	Returns a CharPredicate that evaluates true if either this predicate evaluates to true, or the character is in the range of [from, to].
static CharPredicate	range(char from, char to)	Returns a CharPredicate for the range of characters: [from, to].
boolean	test(char ch)	Returns true if ch satisfies this predicate.

test

boolean test(char ch)

Returns true if ch satisfies this predicate.

or

default CharPredicate or(CharPredicate that)

Returns a CharPredicate that evaluates true if either this or that predicate evaluate to true.

and

default CharPredicate and(CharPredicate that)

Returns a CharPredicate that evaluates true if both this and that predicate evaluate to true.
