Java Problem

I. Solve the following programming problem in Java language. Provide the CODE and a SCREENSHOT of a test run of the code.

Design a program that merges the content of two text files containing chemical elements sorted by atomic number and produces a sorted file of elements. The program should read the content from the two files, and outputs the data ordered by atomic number to the output file. Assume the name of the output file. Use the provided files. The format of each file will be as following:

ATOMIC_NUMBER

ELEMENT_NAME

ELEMENT_ABBREVIATION

ATOMIC_WEIGHT

These is my code it doesn't work I need help:

ChemicalTest.java

package chemicaltest;

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileNotFoundException;

import java.io.FileWriter;

import java.io.IOException;

import java.util.Arrays;

import java.util.Scanner;

public class ChemicalTest {

    public static void main(String[] args) throws IOException {

      File file = new File("inp1.txt");

      Chemical c[]=new Chemical[18];

      int num;

      String nam;

      String abbre;

      double weight;

      int i=0;

    try {

        Scanner sc = new Scanner(file);

        while (sc.hasNextLine()) {

          num=sc.nextInt();

          nam=sc.next();

          abbre=sc.next();

          weight=sc.nextDouble();

          c[i]=new Chemical(num,nam,abbre,weight);

          i++;

        }

       sc.close();

    }

    catch (FileNotFoundException e) {

    }

   file = new File("inp2.txt");

    try {

        Scanner sc = new Scanner(file);

        while (sc.hasNextLine()) {

          num=sc.nextInt();

          nam=sc.next();

          abbre=sc.next();

          weight=sc.nextDouble();

          c[i]=new Chemical(num,nam,abbre,weight);

          i++;

        }

        sc.close();

    }

    catch (FileNotFoundException e) {

    }

    Arrays.sort(c);

    file = new File("out.txt");

    BufferedWriter out = new BufferedWriter(new FileWriter(file));

    for(int k=0;k<i;k++)

    {

        out.write(Integer.toString(c[k].atomicNumber));

        out.newLine();

        out.write(c[k].name);

        out.newLine();

        out.write(c[k].abbrev);

        out.newLine();

        out.write(Double.toString(c[k].atomicWeight));

        out.newLine();

    }

    out.close();

    }

}

Chemical.java

package chemicaltest;

public class Chemical implements Comparable<Chemical> {

    int atomicNumber;

    String name;

    String abbrev;

    double atomicWeight;

    public Chemical(int a,String n,String abbr,double w)

    {

        atomicNumber=a;

        name=n;

        abbrev=abbr;

        atomicWeight=w;

    }

    @Override

    public int compareTo(Chemical item) {

        return Integer.compare(this.atomicNumber, item.atomicNumber);

    }

}
