带小数点的String 转int java.lang.Double cannot be cast to java.lang.Integer

 

带小数点的String转int

HashMap<String, Object> map = new HashMap<String,Object>();
map.put("taskID", 10086);

map里取出来直接转型的话会报错

(Integer) param.get("taskID")

java.lang.ClassCastException: java.lang.Double cannot be cast to java.lang.Integer

解决方法

String taskId ="10086.0";
iTaskId = Double.valueOf(taskId).intValue();
