Design a said scores of class Fraction, this class with two type int variables respectively and the denominator,

The constructor of this class is:



Fraction (int a, int b)

Constructs an a/b grade,



This class is to provide the following functions:



Double toDouble ();

Converts scores to double

Fraction plus Fraction (r);

Their grades and scores of r, create a new Fraction of object, pay attention to the fourth grade learned how two points together ha,

Fraction multiply Fraction (r);

Multiply their scores and r scores together, create a new Fraction of objects,

Void the print ();

Themselves in the form of "molecular/denominator" output to standard output, with a carriage return and line feed, if the score is 1/1, should the output 1, when molecules is greater than the denominator, don't need to put forward the integer part, namely 31/30 is a correct output,



Note that in creating and after operation should be reduced score is the simplest form, such as by 2/4 should be reduced to 1/2,



Class with the following code you wrote together, and please do not modify this code:



import java.util.Scanner;



Public class Main {



Public static void main (String [] args) {

Scanner in=new Scanner (System. In);

Fraction a=new Fraction (in nextInt (), in the nextInt ());

Fraction b=new Fraction (in nextInt (), in the nextInt ());

a.print();

P. rint ();

Amy polumbo lus (b). Print ();

Arjun ultiply (b) plus (new Fraction (5, 6)). Print ();

a.print();

P. rint ();

in.close();

}



}



Note that the definition of your class should begin like this:



The class Fraction {



That is to say, in front of your class class don't have a public,



Input format:

Application runtime get four Numbers, constitute two points respectively, was followed by molecular and the denominator,



The output format:

Output some formula, the input and output are completed by the Main type of code, your code don't input and output,



Input the sample:

4 1 2 3



The output sample:

1/2

A third

5/6

1

1/2

A third

Are you sure you're running the code posted above code is the same with you, I run the results did not appear in the static reference non-static member's error, as for your last error, System. Out. Print (aa and bb); Without this method, you should be to print out the result, rewritten into a string concatenation

1. I'm pretty sure this is the code
2. The bug I just solved it
