public class ArabicTextExtractor {
    public static String extractArabicText(String text) {
        StringBuilder result = new StringBuilder();
        
        for (int i = 0; i < text.length(); i++) {
            char c = text.charAt(i);
            
            if (Character.isLetter(c) && Character.UnicodeBlock.of(c) == Character.UnicodeBlock.ARABIC) {
                result.append(c);
            }
        }

    }
    
    public static void main(String[] args) {
        String mixedText = "Hello 你好 مرحبا こんにちは";
        String arabicText = extractArabicText(mixedText);
