Explanation / Answer

I'm not sure what you wanted for the program header information, so that one line is unfinished. The rest of it works, though: import java.io.*; import java.text.*; public class CustomerInfo{ int custID, transNr, custCount; double totalPurch, totalPay, totEndBal, avgEndBal, balFrwd, amt, interest, endBal, totInt; String custName, type, date; DecimalFormat twoDigitsPastPoint = new DecimalFormat ("0.00"); //rounds off money amts to two places after the decimal BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); public void PrgmHeader(){ //Output header information. } public void ReportOut(){ avgEndBal = Double.parseDouble(twoDigitsPastPoint.format(avgEndBal)); totEndBal = Double.parseDouble(twoDigitsPastPoint.format(totEndBal)); totInt = Double.parseDouble(twoDigitsPastPoint.format(totInt)); System.out.println("Total End Balance: $" + totEndBal); System.out.println("Average End Balance: $" + avgEndBal); System.out.println("Total Interest: " + totInt); } public void Customer(){ CustInit(); GetCustInfo(); CustInfoOut(); System.out.println("Input Transaction Number or -1 to end."); try{ transNr = Integer.parseInt(reader.readLine()); while(transNr > 0){ Transaction(); } } catch (IOException ioe){ } CustSummary(); CustSumOut(); custCount++; totEndBal = totEndBal + endBal; totInt = totInt + interest; System.out.println("Input Customer ID"); try{ custID = Integer.parseInt(reader.readLine()); } catch (IOException ioe){ } } public void CalcAvg(){ avgEndBal = totEndBal / custCount; } public void Transaction(){ GetTransInfo(); TransInfoOut(); UpdateCustTots(); System.out.println("Input Transaction Number."); try{ transNr = Integer.parseInt(reader.readLine()); } catch (IOException ioe){ } } public void ReportInit(){ totEndBal = 0; totInt = 0; custCount = 0; } public void CustInit(){ totalPurch = 0; totalPay = 0; } public void GetCustInfo(){ System.out.println("Input Customer Name."); try{ custName = reader.readLine(); } catch (IOException ioe){ } System.out.println("Input Balance Frwd."); try{ balFrwd = Double.parseDouble(reader.readLine()); } catch (IOException ioe){ } } public void CustInfoOut(){ System.out.println("Customer ID: " + custID); System.out.println("Customer name: " + custName); System.out.println("Balance Frwd: $" + balFrwd); } public void GetTransInfo(){ System.out.println("Input Type."); try{ type = reader.readLine(); System.out.println("Input Date."); date = reader.readLine(); System.out.println("Input Amount."); amt = Double.parseDouble(reader.readLine()); } catch (IOException ioe){ } } public void TransInfoOut(){ System.out.println("Transaction Number: " + transNr); System.out.println("Type: " + type); System.out.println("Date: " + date); System.out.println("Amount: " + amt); } public void UpdateCustTots(){ if(type.equalsIgnoreCase("d")){ totalPurch = totalPurch + amt; } else if(type.equalsIgnoreCase("c")){ totalPay = totalPay + amt; } else{ System.out.println("Invalid type entered - transaction not processed."); } } public void CustSummary(){ if(( (balFrwd-totalPay) > 0)){ interest = (balFrwd-totalPay) * .005; } else{ interest = 0; } endBal = balFrwd + totalPurch-totalPay + interest; } public void CustSumOut(){ interest = Double.parseDouble(twoDigitsPastPoint.format(interest)); endBal = Double.parseDouble(twoDigitsPastPoint.format(endBal)); System.out.println("Total Purchase: " + totalPurch); System.out.println("Total Pay: " + totalPay); System.out.println("Interest: " + interest); System.out.println("Ending Balance: " + interest); } public static void main(String[] args){ CustomerInfo c = new CustomerInfo(); c.PrgmHeader(); c.ReportInit(); System.out.println("Input Customer ID or -1 to end."); try{ c.custID = Integer.parseInt(c.reader.readLine()); } catch (IOException ioe){ } while(c.custID > 0){ c.Customer(); } c.CalcAvg(); c.ReportOut(); } }
