java - Java:将ArrayList转换为String？

我尝试打印输入号码的反面而没有任何for循环。但是我在打印Arraylist时遇到了一些问题。如何将Arraylist [3，5，4，1]打印为3541-不带括号，逗号和空格？

如果不可能，如何将ArrayList元素添加到字符串列表然后打印？

public static void main(String[] args) {

    int yil, bolum = 0, kalan;
    Scanner klavye = new Scanner(System.in);
    ArrayList liste = new ArrayList();
    //String listeStr = new String();
    System.out.println("Yıl Girin: "); // enter the 1453
    yil = klavye.nextInt();

    do{ // process makes 1453 separate then write in the arraylist like that [3, 5, 4,1]

        kalan = yil % 10;
        liste.add(kalan);
        bolum = yil / 10;
        yil = bolum;

    }while( bolum != 0 );

    System.out.println("Sayının Tersi: " + ....); //reverse of the 1453
    klavye.close();
}

最佳答案

public static void main(String[] args) {


    int yil, bolum = 0, kalan;
    ArrayList liste = new ArrayList();
    System.out.println("Yıl Girin: "); // enter the 1453
    yil = 1453;

    String s="";
    do { // process makes 1453 separate then write in the arraylist like that [3, 5, 4,1]

        kalan = yil % 10;
        liste.add(kalan);
        s= s + kalan;  // <------- THE SOLUTION AT HERE  -------

        bolum = yil / 10;
        yil = bolum;

    } while (bolum != 0);

    System.out.println("Sayının Tersi: " + s ); //reverse of the 1453

}
