Java replace（）问题

这是我简化您的代码并获得正确结果的方式：

    String rope = "and , and,and , to , to,to , you ,you , you, for ,for , for,a , a,e , e,i , i,o , o,u , u";   // rope = rope.replaceAll(" ", "");    rope = rope.replaceAll("and", "&");    rope = rope.replaceAll("to", "2");    rope = rope.replaceAll("you", "U");    rope = rope.replaceAll("for", "4");    rope = rope.replaceAll("a", "");    rope = rope.replaceAll("e", "");    rope = rope.replaceAll("i", "");    rope = rope.replaceAll("o", "");    rope = rope.replaceAll("u", "");    System.out.println(rope);
