Question

Getting Index out of bound exception for

    for (int recordData = 0; recordData < recordDataList.size(); recordData++)
    {
        RecordData nextRecordData = recordDataList.get(recordData + 1);
        if (nextRecordData.getRespondentId() !=     
            recordDataList.get(recordData).getRespondentId()) {
            rowDataNumber++;
        }
    }

Here size is 3. But i need to compare third data with second also.
I have modified my like

    for (int i = 1; i < recordDataList.size(); i++) {
                         RecordData recordData = recordDataList.get(i - 1);
                RecordData nextRecordData = recordDataList.get(i);
                         commentData = recordData.getCommentText();
if (nextRecordData.getRespondentId() != recordData
                        .getRespondentId()) {
                    rowDataNumber++;
                }
}

the size is three i am getting only first two data in commentData,the third data is not getting shown.

Answer 1

As you are comparing a value with the next value, there needs to be a next value.

You need to use

for (int i = 0; i < recordDataList.size() - 1; i++) {
    RecordData recordData = recordDataList.get(i);
    RecordData nextRecordData = recordDataList.get(i + 1);

or

for (int i = 1; i < recordDataList.size(); i++) {
    RecordData recordData = recordDataList.get(i - 1);
    RecordData nextRecordData = recordDataList.get(i);
