Regarding String array

Question

I have a input string in this format
1     Aviation Lamp     1     Nos     3700     3,7002     Lighting Arrester     1     Nos     1600'     1,6003     Aviataion Lamp Cable     31     Rmt     '     270     8,370
I can able to display the 3,700 1,600 8,370 these values i want to store in a String array for this i have written code in this way but unable to succeed
Code:
String sub="1     Aviation Lamp     1     Nos     3700     3,7002     Lighting Arrester     1     Nos     1600'     1,6003     Aviataion Lamp Cable     31     Rmt     '     270     8,370";
i=3;
Matcher tdata = Pattern.compile(("\\d*,\\d{3}"), Pattern.CASE_INSENSITIVE).matcher(sub);//Matching is performed using regular expression here
while (tdata.find()) {
for (int ij = 0; ij < i; ij++) {
table[ij] = tdata.group();
System.out.println(" Result "+tdata.group());//trying to load values in string array
System.out.println(" "+tdata.group());
for (int ik = 0; ik < 3; ik++) {
System.out.println(" output " + table[ik]);//Displaying only 8,370.
Any suggestions please welcome

Hi Praveen
Matcher tdata = Pattern.compile(("\\d*,d{3}"), Pattern.CASE_INSENSITIVE).matcher(sub);
From above statement of your code, if u see u have Pattern Object which contain regular expression of
one digit followed by comma and exactly three digits.
Than your trying to match your string sub with the above regular expression so this wont match,
you can confirm by using method tdata.matches() , this method returns true if it matches false if it don't.
you can use the following code to make your stuff work
String sub = "1 Aviation Lamp 1 Nos 3700 3,7002 Lighting Arrester 1 Nos 1600' 1,6003 Aviataion Lamp"
+ "Cable 31 Rmt ' 270 8,370";
          String []SplitSub = sub.split("\\s");
          Pattern p = Pattern.compile("\\d,\\d{3,}", Pattern.CASE_INSENSITIVE);
          int ij =0;
          String table[] = new String[SplitSub.length];
          if(SplitSub.length > 1)
               for(int i =0; i < SplitSub.length ; i++)
                    Matcher m = p.matcher(SplitSub);
                    if(m.matches())
                         table[ij++] = SplitSub[i].substring(0,5);
                         System.out.println(" Result " + SplitSub[i].substring(0,5));
