c语言u8如何转化为int,String类型如何转换成int类型相加

1   BigDecimal deepsleepcount = new BigDecimal(resulHeartrateDeepSleep);

2   BigDecimal lightsleepcount = new BigDecimal(resulHeartrate);

3   BigDecimal Moderatesleep = new BigDecimal(resulHeartrateSleepModerate);

4   Double lideepse =  lightsleepcount.add(deepsleepcount).doubleValue();

5  BigDecimal lightsleepcount1 = new BigDecimal(lideepse.toString());

6  Double count =  Moderatesleep.add(lightsleepcount1).doubleValue();

首先这个string bixu必须是正数类型否则会报错

1    BigDecimal deepsleepcount = new BigDecimal(String类型);

2   BigDecimal lightsleepcount = new BigDecimal(String类型);

4   Double lideepse =  lightsleepcount.add(deepsleepcount).doubleValue();

lideepse 总数

如果还想把两次的总数之和与第三次的参数相加

就ji将4步 lideepse.toString 一下就又是string类型了继续add方法了进行相加了
