在以下情况下如何解决IllegalThreadStateException

Question

我在启动ccObj线程时收到IllegalThreadStateException，因为此线程已启动两次。但是，只要我的输入与CC文本匹配，我就需要启动线程。我尝试在If循环内创建线程对象，但是需要在if条件之前使用此对象。如果每当付款类型为“ CC”时有任何方式启动此线程，请帮助我

CreditCardPayment ccObj = new CreditCardPayment();
System.out.println("Enter the number of payments:");
        int numberOfPayments = Integer.parseInt(reader.readLine());

        System.out.println("Enter the payment details (Invoice ID, ACC Number, Payment Amount, Payment Type)");
        List<String> input = new ArrayList<String>();
        for(int i=0;i<numberOfPayments;i++) {
            input.add(reader.readLine());
        }        
for(String list : input)
        {
String[] inputarr = list.split(",");
            String paytype = inputarr[3];               
ccObj.setCardNumber(inputarr[1]);
        }

 else if(paytype.equalsIgnoreCase("CC"))
            {

                ccObj.start();
                ccObj.join();

            }
