java字符串根据空格截取并存进ArrayList，并在每个元素前后加上/

public class List {
    public static void main(String[] args) {
    String s = "abc nnn ooo/xzsxc bs";
    System.out.println("原字符串："+s);
    System.out.println();
    String a[] = s.split(" ");
    ArrayList b = new ArrayList();
    for (int i = 0; i < a.length;i++){
        b.add(a[i]);
        System.out.println(a[i]);
    }
        System.out.println();
        for( int i=0;i<a.length;i++ ){
            a[i] = a[i].replaceAll(a[i],"/"+ a[i] + "/");
            System.out.println(a[i]);
        }
    }
}
