Assigning Values from a file to an Array

Question

hey everyone I am working on a program that inputs values from a text file into an array i got the first array to work but the second array does not work. Please if you have a moment lend a hand. Here is my code. the program compiles fine but will not run right with the second array in it. The second array is called "B"
import java.util.*;
import java.io.*;
import javax.swing.*;
class algorithmAssignment1{
     public static void main (String[] args)throws IOException{
     int mark, counter, arrayAsize, mark2;
     counter=0;
     arrayAsize=100;
     int [] A= new int[arrayAsize];
     int [] B= new int[arrayAsize];
    String fileName = "arraynumbersa.txt";
    String value,value2;
    BufferedReader input;
    input = new BufferedReader (new FileReader (fileName));
    value = input.readLine ();
   while (value != null){
       mark = Integer.parseInt (value);
       A[counter]=mark;
       counter=counter+1;
       value = input.readLine ();
  /*  String fileName2 = "arraynumbersb.txt";
    BufferedReader input2;
    input2 = new BufferedReader (new FileReader (fileName2));
    value2 = input2.readLine ();     
     while (value2 != null){
       mark2 = Integer.parseInt (value2);
       B[counter]=mark2;
       counter=counter+1;
       value2 = input2.readLine ();
     bubbleSort(A,A.length);
     bubbleSort(B,B.length);
     System.out.println("Here is list A");
     for (int i = 0; i < A.length; i++){
         System.out.println( A[i] );
    System.out.println();
    System.out.println("Here is list B");
    for (int i=0;i<B.length;i++){
         System.out.println(B);
/*change
for (int i=0;i<A.length;i++){
     for (int j=0;j<B.length;j++){
          if (A[i]==B[j]){
               System.out.println("Numbers that are in list A and B are "+ B[j]);
static void bubbleSort(int numbers[], int array_size){
     int i, j, temp;
     for (i = (array_size - 1); i >= 0; i--)
     for (j = 1; j <= i; j++)
     if (numbers[j-1] > numbers[j]){
     temp = numbers[j-1];
                         numbers[j-1] = numbers[j];
                         numbers[j] = temp;

Answer 1

Ok new problem now. I have to get the duplicates to go into a new array in order to display the duplicates. I can't figure out why it just lists the one duplicate but not the others.(It lists the final duplicate)
Here is my code:
import java.util.*;
import java.io.*;
import javax.swing.*;
class algorithmAssignment1{
     public static void main (String[] args)throws IOException{
     int mark, counter, arrayAsize, mark2,counter2;
     counter=0;
     arrayAsize=100;
     counter2=0;
     int [] A= new int[arrayAsize];
     int [] B= new int[arrayAsize];
     int [] C=new int [arrayAsize];
    String fileName = "arraynumbersa.txt";
    String value,value2;
    BufferedReader input;
    input = new BufferedReader (new FileReader (fileName));
    value = input.readLine ();
   while (value != null){
       mark = Integer.parseInt (value);
       A[counter]=mark;
       counter=counter+1;
       value = input.readLine ();
    String fileName2 = "arraynumbersb.txt";
    BufferedReader input2;
    input2 = new BufferedReader (new FileReader (fileName2));
    value2 = input2.readLine ();     
     while (value2 != null){
       mark2 = Integer.parseInt (value2);
       B[counter2]=mark2;
       counter2=counter2+1;
       value2 = input2.readLine ();
     bubbleSort(A,A.length);
     bubbleSort(B,B.length);
     System.out.println("Here is list A");
     for (int i = 0; i < A.length; i++){
         System.out.println( A[i] );
    System.out.println();
    System.out.println("Here is list B");
    for (int i=0;i<B.length;i++){
         System.out.println(B);
for (int i=0;i<A.length;i++){
     for (int j=0;j<B.length;j++){
          if (A[i]==B[j]){
               for (int k=0;k<C.length;k++){
                    C[k]=(B[j]);
               System.out.println("Here"+B[j]);
System.out.println("Here are A and B");
for (int i=0;i<C.length;i++){
     System.out.println(C[i]);
static void bubbleSort(int numbers[], int array_size){
     int i, j, temp;
     for (i = (array_size - 1); i >= 0; i--)
     for (j = 1; j <= i; j++)
     if (numbers[j-1] > numbers[j]){
     temp = numbers[j-1];
                         numbers[j-1] = numbers[j];
                         numbers[j] = temp;
