#savol isDigit nomli funksiyasi yarating va parametrga String ko'rinishida satr berilgan bo'lsin. Satr tarkibida raqam bor yoki yo'qligi topuvchi dastur tuzing. Agar satr tarkibida son bo'lsa true, aks holda false qiymat qaytaring? #javob #isDigit Java dasturlash tilida public class isDigitFunction { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.println(isDigit(scanner.nextLine())); } private static boolean isDigit(String str){ for (int i = 0; i < str.length(); i++) { char ch = str.charAt(i); if (ch >= 48 && ch <= 57){ return true; } } return false; } } Telegram | Viktorina bot | Portfolio
