Reading from a text file and displaying the contents with in a frame

Question

Hi All,
I am trying to read some data from a text file and display it on a AWT Frame. The contents of the text file are as follows:
pcode1,pname1,price1,sname1,
pcode2,pname2,price2,sname1,
I am writing a method to read the contents from a text file and store them into a string by using FileInputStream and InputStreamReader.
Now I am dividing the string(which has the contents of the text file) into tokens using the StringTokenizer class. The method is as show below
void ReadTextFile()
                    FileInputStream fis=new FileInputStream(new File("nieman.txt"));
                     InputStreamReader isr=new InputStreamReader(fis);
                     char[] buf=new char[1024];
                     isr.read(buf,0,1024);
                     fstr=new String(buf);
                     String Tokenizer st=new StringTokenizer(fstr,",");
                     while(st.hasMoreTokens())
                                      pcode1=st.nextToken();
                           pname1=st.nextToken();
          price1=st.nextToken();
                          sname1=st.nextToken();
     } //close of while loop
                } //close of methodHere goes my problem: I am unable to display the values of pcode1,pname1,price1,sname1 when I am trying to access them from outside the ReadTextFile method as they are storing "null" values . I want to create a persistent string variable so that I can access the contents of the string variable from anywhere with in the java file. Please provide your comments for this problem as early as possible.
Thanks in advance.

If pcode1,pname1,price1,sname1 are global variables, which I assume they are, then simply put the word static in front of them. That way, any class in your file can access those values by simply using this notation:
MyClassName.pcode1;
MyClassName.pname1;
MyClassName.price1;
MyClassName.sname1
