Question

I have CSV file which contains 6 column separated by comma:

VendorCode, VendorName, Material, MaterialDescription, Reason, Quantity    

I am able to retrieve data from each column except “Reason” column as it contains values in that column as:

Pitted, Rusty     

( I mean comma separated values are there in that column)

(So Pitted value is inserted in “Reason “ arraylist & Rusty is inserted in “Quantity” arraylist For that particular line)

For eg: :

One row of csv file contains:

AA90,ABC LTD.,2.71E+11,ASSY/LAM`E'CE-MSSL-RINDER,"VisualCrack,B.H,Damage,Burr",330

DESIRED OUTPUT :
“pitty,rusted” should be treated as single string and stored in database

i have tried this

while ((thisLine = myInput2.readLine()) != null)  {

    String[] str = thisLine.split(",");
    for(int j=0; j<str.length; j++) {
        switch(j) {
            case 0: DR_VendorCode.add(str[j]);//getContents()); break;
            case 1:DR_VendorName.add(str[j]);//getContents()); break;
            ....
        }

        i1++;
    }
}

for(int k=0;k<DR_VendorCode.size()+1;k++) {

    String DR_VCODE=DR_VendorCode.get(k).toString();
    String DR_VNAME=DR_VendorName.get(k).toString();
    ....
}

Here you go …

String regex = "\"[^\"]+\"|[^,]+";
Pattern p = Pattern.compile(regex);
Matcher m = p.matcher(thisLine);
while(m.find()) {
    System.out.println(thisLine.substring(m.start(),m.end()));
    // I suppose you could construct an array here rather than just printing it
}

Output …

AA90
ABC LTD.
2.71E+11
ASSY/LAM`E'CE-MSSL-RINDER
"VisualCrack,B.H,Damage,Burr"
330

To handle 5th (actually any but only one) column with multiple embedded quotes …

String regex = "\".*\"|[^,]+";

Output …

AA90
ABC LTD.
2.71E+11
ASSY/LAM`E'CE-MSSL-RINDER
"VisualCrack,B.H,"Damage",Burr"
330
