Question

我在一天前制作了相同的设定代码并且工作正常。现在它得到了很多我不理解的错误。有人可以帮忙吗？感谢。

import java.util.Scanner;
import java.io.PrintStream;
import java.lang.Math;
import type.lib.*;

public class Fraction
{
    public static void main(String[] args)
    {
        Scanner scan = new Scanner(System.in);
        PrintStream print = new PrintStream(System.out);
        print.println("For each fraction enter its numerator/denominator,");
        print.println("pressing ENTER after each");
        print.println("Enter x");
        Fraction a = new Fraction(scan.nextLong(),scan.nextLong());
        print.println("Enter y");
        Fraction b = new Fraction(scan.nextLong(),scan.nextLong());
        a.add(b);
        Fraction a = x;
        print.println("Enter z");
        Fraction c = new Fraction(scan.nextLong(),scan.nextLong());
        print.println("Enter t");
        Fraction d = new Fraction(scan.nextLong(),scan.nextLong());
        c.add(d);
        Fraction c = y;
        x.divide(y);
        print.println("A = ");
        print.println(x.toString());
    }
}

进行以下更改，并创建使用的方法，例如添加和分割

public class Fraction {
        public Fraction(long nextLong, long nextLong2) {  // add the constructor

            // TODO Auto-generated constructor stub
        }

        public static void main(String[] args)
        {
            Scanner scan = new Scanner(System.in);
            PrintStream print = new PrintStream(System.out);
            print.println("For each fraction enter its numerator/denominator,");
            print.println("pressing ENTER after each");
            print.println("Enter x");
            Fraction a = new Fraction(scan.nextLong(),scan.nextLong());
            print.println("Enter y");
            Fraction b = new Fraction(scan.nextLong(),scan.nextLong());
            a.add(b);
            Fraction x = a;  // change the fraction places
            print.println("Enter z");
            Fraction c = new Fraction(scan.nextLong(),scan.nextLong());
            print.println("Enter t");
            Fraction d = new Fraction(scan.nextLong(),scan.nextLong());
            c.add(d);     //create add method
            Fraction y =c;   // change the fraction places
            x.divide(y);   // create divide method
            print.println("A = ");
            print.println(x.toString());
        }

//Create the required methods..
private void divide(Fraction y) {
            // TODO Auto-generated method stub

        }


        private void add() {
            // TODO Auto-generated method stub

        }
}

分数创建错误
