This topic seems to be a sequel of http://www.cjsdn.net/post/view?bid=1&id=164560

You could use the toString method of your Rational class in that post.
i.e. (new Rational(a, b)).toString()

or you could add a static method in your Rational class for formatting 有理数
and use
Rational.staticMethodToFormat(a, b)

something like
public static String staticMethodToFormat(int a, int b) {
return (a + "/" + b); // could have used StringBuffer
}
