Stuck in addRecord coding

[cheri_sakura]

Hi,

I am stuck in adding records to record store.
My purpose is to add Subject and Section into one record in recordstore.
Below is part of my coding:

try {
String[] Note = {Subject.getString(),Section.getString()};
//If new record, recId = 0
addRecord(0, Note);
} catch (IOException ex) {
ex.printStackTrace();
}

...
...

private void addRecord(int recId, String[] record) throws IOException {
// Add records to recordStore
ByteArrayOutputStream bout = new ByteArrayOutputStream();
DataOutputStream dout = new DataOutputStream(bout);
for(int i=0; i < record.length; i++) {
dout.writeUTF(record[i].getSubject()); <--- ERROR encountered.
dout.writeUTF(record[i].getSection()); <--- ERROR encountered.
}
dout.close();
byte[] data = bout.toByteArray();
try {
RecordStore store = RecordStore.openRecordStore("NoteLibrary", true);
if (recId == 0)
recId = store.addRecord(data, 0, data.length);
else
store.setRecord(recId, data, 0, data.length);
store.closeRecordStore();
} catch (RecordStoreNotOpenException e) {
e.printStackTrace();
} catch (RecordStoreFullException e) {
e.printStackTrace();
} catch (RecordStoreException e) {
e.printStackTrace();
}
}

Please advise.

DataOutputStream dout = new DataOutputStream(bout);
for(int i=0; i < record.length; i++) {
    dout.writeUTF(record[i]);
}
dout.close();

Just change the lines to the one above. Your String array has a length of 2. [0] is your subject. [1] is your section. More about Java arrays (which are a bit confusing) in the Java Tutorial&#160;…

checkout the code running perfectly. By the way what error r u facing? Please mention that. Might be the problem is recId.
When u send recId = 0 then program runs ok but when u send RecId = value other than 0 or 1 like 2 or 3 then u are facing problem coz recordId is not exist when u set the record at recId = 2 or 3. Its just my guess. Please mention the exception comes if any.

private void addRecord(int recId) {
// Add records to recordStore

        ByteArrayOutputStream bout = new ByteArrayOutputStream();
        DataOutputStream dout = new DataOutputStream(bout);
        try {
            dout.writeUTF("Jitendra");
            dout.writeUTF("Agarwal");

            dout.close();
            byte[] data = bout.toByteArray();

            RecordStore store = RecordStore.openRecordStore("NoteLibrary", true);
            if (recId == 0) {
                recId = store.addRecord(data, 0, data.length);
            } else {
                store.setRecord(recId, data, 0, data.length);
            }
            store.closeRecordStore();
        } catch (RecordStoreNotOpenException e) {
            e.printStackTrace();
        } catch (RecordStoreFullException e) {
            e.printStackTrace();
        } catch (RecordStoreException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
