接收的String類型轉換Integer Integer.parseInt();

String insurance = (String) params.get("companyName");
Integer insur = Integer.parseInt(insurance);
insuranceCompany.setId(insur);
setupInsuranceRelation.setInsuranceCompany(insuranceCompany);//

 

Integer轉String

Integer s = 10;

String reg = Integer.toString(s);

 

 

public static void main(String[] args) {
 // 浮點數的打印
// BigDecimal amount = new BigDecimal("10000000000.67");
// System.out.println(amount.stripTrailingZeros().toPlainString());
//
//// // 普通的數字字符串
//// System.out.println(new BigDecimal("100.000").toString());
////
//// // 去除末尾多余的0
//// System.out.println(new BigDecimal("100.000").stripTrailingZeros().toString());
////
//// // 避免輸出科學計數法
//// System.out.println(new BigDecimal("100.000").stripTrailingZeros().toPlainString());
//
// }
