How can I map the data to four values for the BalanceDTO instead of two like in the example I made for the NetDTO. Any help will be appreciated, I want to find the 4 values to map them. I just need help in the loop to find the values. Thanks in Advance.

/// 2 values CSV File public void toCSVFile(List receivedDataList) { logger.info("Executing net value strategy..."); List secondaryList = receivedDataList; List netDTOList = new ArrayList<>(); //maps data to netDTO, finds minuend and subtrahend for (ReceivedData y : receivedDataList) { for (ReceivedData x : secondaryList) { if (y.getLotid().equals(x.getLotid()) && y.getMaterialNumber().equals(x.getMaterialNumber()) && y.getOperKey().equals(x.getOperKey()) && y.getOrderID().equals(x.getOrderID()) && y.getSerialID().equals(x.getSerialID()) && y.getStepKey().equals(x.getStepKey()) && !y.getDataCollectionID().equals(x.getDataCollectionID()) && y.getType().equals("MINUEND") && x.getType().equals("SUBTRAHEND")) { NetDTO netDTO = new NetDTO(y, x); netDTOList.add(netDTO); } } } writer(receivedDataList.get(0).getProcess().getProcessName() + ".csv", netDTOList); } ///// Net DTO public NetDTO(ReceivedData minuend, ReceivedData subtrahend) { this.ordNumber = minuend.getOrdNumber(); this.matNumber = minuend.getMaterialNumber(); this.operator = minuend.getOperator(); this.serialNumber = minuend.getSerialNumber(); this.toolNo = minuend.getToolNo(); this.timeStamp = minuend.getTimeStamp(); this.dcTitleMinuend = minuend.getDcTitle(); this.dcValueMinuend = minuend.getDcValue(); this.dcTitleSubtrahend = subtrahend.getDcTitle(); this.dcValueSubtrahend = subtrahend.getDcValue(); } //// Balance DTO (I want to map the data like I did in the netDTO to this dto. But with 4 values) public BalanceDTO(ReceivedData value1, ReceivedData value2, ReceivedData value3, ReceivedData value4) { this.ordNumber = value1.getOrdNumber(); this.matNumber = value1.getMaterialNumber(); this.operator = value1.getOperator(); this.serialNumber = value1.getSerialNumber(); this.toolNo = value1.getToolNo(); this.timeStamp = value1.getTimeStamp(); this.dcTitleValue1 = value1.getDcTitle(); this.dcValueValue1 = value1.getDcValue(); this.dcTitleValue2 = value2.getDcTitle(); this.dcValueValue2 = value2.getDcValue(); this.dcTitleValue3 = value3.getDcTitle(); this.dcValueValue3 = value3.getDcValue(); this.dcTitleValue4 = value4.getDcTitle(); this.dcValueValue4 = value4.getDcValue(); }

I want to know how can I approach the looping when it comes 3 or more values. In this case, 4 values.
