Timestamp、BigDecimal日常使用

1. Timestamp nowDateStrts = Timestamp.valueOf(nowDateStr);
   Long ll = appointmentTimets**.getTime()**-nowDateStrts.getTime();
   Timestamp format must be yyyy-mm-dd hh:mm:ss[.fffffffff]

2.BigDecimal timeCompensate= new BigDecimal(30.00);
BigDecimal bignum1 = new BigDecimal(“10”);
BigDecimal bignum2 = new BigDecimal(“5”);
BigDecimal bignum3 = null;

//加法
bignum3 = bignum1.add(bignum2);
System.out.println(“和 是：” + bignum3);

//减法
bignum3 = bignum1.subtract(bignum2);
System.out.println(“差 是：” + bignum3);

//乘法
bignum3 = bignum1.multiply(bignum2);
System.out.println(“积 是：” + bignum3);

//除法
bignum3 = bignum1.divide(bignum2);
System.out.println(“商 是：” + bignum3);
