一个构造函数 - 多个参数

我在一些 Java 编程竞赛中找到了一个任务。必须创建仅包含一个参数“文本”和一个构造函数的类 Sentence。这是示例测试代码：

 Sentence s1=new Sentence("only","CAT"),
      s2=new Sentence("and", 2, "mice"),
      s3=new Sentence(s1,s2,"completely","alone"),
      s4=new Sentence(s3, "on the ", new Integer(32), "th street");

 System.out.println(s1); Only cat.
 System.out.println(s2); Only cat and 2 mice.
 System.out.println(s3); Only cat and 2 mice completely alone.
 System.out.println(s4); Only cat and 2 mice completely alone on the 32th street.

一个构造函数如何可以提供不同的参数集？是否有类似动态构造函数的东西可以识别发送的值？

利用varargs http://java.sun.com/j2se/1.5.0/docs/guide/language/varargs.html.

public class Sentence {

    public Sentence(Object... text) {
        // ...
    }

}

自己填写构造函数逻辑。然而，确定所有类型可能会变得有点糟糕。你可以利用Object#toString()并让Sentence类也实现一个。
