拆分char[]并将值存储在不同的数组中

char[] chars = {'a', 'b', '1', '2', '$', '#'};
List<Character> letters = new ArrayList<>();
List<Character> digits = new ArrayList<>();
List<Character> symbols = new ArrayList<>();

for (char c : chars) {
    if (Character.isLetter(c)) {
        letters.add(c);
    } else if (Character.isDigit(c)) {
        digits.add(c);
    } else {
        symbols.add(c);
    }
}

// 打印存储结果
System.out.println("Letters: " + letters);
System.out.println("Digits: " + digits);
System.out.println("Symbols: " + symbols);
