Logical error in code, please help, thanks alot.

Question

I have this file Socks.java which reads in a file containing information about a sock drawer. The file is of the format:
11
red athletic
green casual
blue athletic
blue athletic
red athletic
so when the program runs, it is supposed to output the socks that are pairs: so it would output
1 pair red athletic
1 pair blue athletic
my code compiles and runs fine and i am testing it with println statements, but I am not getting the desired ouput. Can someone look over it and see if they spot what is wrong. Right now in the code I am seeing what the value of socks[i] and socks[j] is by printing them out as you will notice. If anyone can help, I appreciate it. Thanks so much for all your wonderful help
Here is the code:
import java.io.*;
public class Socks {
public static void main(String args[])
try
String socks[] = new String[1000];
int pairs[] = new int[500];
int numOfsocks;
int i;
int j;     
FileReader fr = new FileReader("test.txt");
BufferedReader inFile = new BufferedReader(fr);
numOfsocks = Integer.parseInt(inFile.readLine());
int possiblePairs = numOfsocks/2;
//System.out.println(numOfsocks);
//System.out.println(possiblePairs);
for(i = 0; i < numOfsocks; i++)
socks[i] = inFile.readLine();
//for(i = 0; i < numOfsocks; i++)
//System.out.println(socks);
for(i = 0; i <= possiblePairs;i++)
for(j = i; j <= possiblePairs;j++)
System.out.println(socks[i]);
System.out.println(socks[j]);
//if(pairs[i] >= 2)
//System.out.println(pairs[i]/2 + " pairs" + socks[i]);
inFile.close();     
catch(IOException e){}
          System.out.println("File Not Found or no File Specified");

Try the following quickly revised version of your code.
import java.io.*;
public class Socks {
public static void main(String args[])
  try
    String socks[] = new String[1000];
    int pairs[] = new int[500];
    int numOfsocks;
    int i;
    int j;
    FileReader fr = new FileReader("test.txt");
    BufferedReader inFile = new BufferedReader(fr);
    numOfsocks = Integer.parseInt(inFile.readLine());
    for(i = 0; i < numOfsocks; i++)
      socks[i] = inFile.readLine();
    for(i = 0; i < numOfsocks; i++)
      if (socks[i] != null)
        pairs[i]++;
        for(j = i + 1; j < numOfsocks; j++)
            if (socks.equals(socks[j]))
pairs[i]++;
socks[j] = null;
System.out.println(pairs[i]/2 + " pairs " + socks[i]);
inFile.close();
catch(IOException e){
e.printStackTrace();
