read coulm from file and store it to array

[newbie_]

Hello guys i am new to java and i have some problem that going to make my head explode i am stuck on this thing for a week now i need to read data file by column not by lines for example i have the following data file

6, 148, 72, 35, 0, 336, 0627, 50, 2
8, 183, 64, 0, 0, 233, 0672, 32, 2
1, 85, 66, 29
1, 89, 66, 23, 94, 281, 0167, 21, 1
0, 137, 40, 35, 168, 431, 2288, 33, 2, 10, 9, 125
5, 116, 74, 0, 0, 256, 0201, 30, 1

i need to read it coulmn by coulmn and store it to arrays for exaample the first array would be {6,8,1,1,0,5} and so on all what i have done is read it line by line and thats not working for me this what i've done so far

public class VariableTransformation
{

private String FileName = "";
private FileReader FileReader;	
private BufferedReader buffFile;
private ArrayList<string\[\]> attrDomainList = new ArrayList<string\[\]>();	
private String\[\] item=null;


	


public static void main(String\[\] args) 
{
	VariableTransformation tds = new VariableTransformation();
	Scanner input=new Scanner(System.in);
	System.out.println("===============================================");
	System.out.print("Enter the file name>> ");
	String filename;
	filename=input.next();
	tds.fileLoad(filename);
	System.out.println("===============================================");
		
}

public void fileLoad(String fileName)
{
	String line = "";
	String\[\] attrDomain;
	FileName = fileName;
		
	
	System.out.println("> Reading File..");
	try {
		int lineCount=0;
		int size=0;
		FileReader = new FileReader(FileName);
		buffFile = new BufferedReader(FileReader);

		try {
											
			while((line = buffFile.readLine()) != null)
			{
					item = line.split(",");
					size=item.length;
					attrDomain=new String\[size\];
					for (int i = 0; i < item.length; i++) {
						attrDomain\[i\]=item\[i\];							
					}						
					attrDomainList.add(attrDomain);
					lineCount++;
			}
			
			printData(attrDomainList);
			System.out.println("> Finish File Reading.");
			System.out.println("Number of Lines>> "+lineCount);
			System.out.println("===============================================");
			
		} 
		catch (IOException e) {
			System.out.println(e.getStackTrace().toString());
			System.out.println("# Error while reading file .");
		}
		finally
		{				
			try {buffFile.close();} catch (IOException e) {e.printStackTrace();}
			try {FileR
