Aşağıda bazı örnekler verdim ve Latince'nin yeterli olduğunu düşündüm, ama ...
Tüm bu işaretleri giriş dizesinden kaldırmanın ve yalnızca farklı dillerde harfleri ve noktalama işaretlerini tutmanın bir yolu var mı?
Düzenledikten sonra, Character.getType
yöntemi kullanarak yeni bir çözüm geliştirdi ve bu en iyi çekim gibi görünüyor.

Kod, String'i kod noktalarına aktararak çalışır. Daha sonra karakterleri bir int
diziye filtrelemek için lambdas'ı kullanarak diziyi String'e dönüştürürüz.
Harfler ve boşluklar filtreye Karakter yöntemleri, noktalama iyi değil kullanarak kullanıyorsunuz. Başarısız girişim .
Unicode bloklar beyaz unicode bloklar programcı belirtir kullanılarak filtre izin verilen. Başarısız girişim .
Unicode blokları siyah programcı belirtir olarak izin verilmeyen Unicode bloklarını kullanarak filtre. Başarısız girişim .
Kategori statik yöntem kullanılarak filtre Character.getType
. Programcı category
dizide hangi türlere izin verileceğini tanımlayabilir . ÇALIŞMALARI 😨😱😰😲😀.
