本技能提供阿里巴巴Java开发手册中的高级编程相关规范，包括集合处理、并发处理和控制语句。
hashCode和equals的处理，遵循如下规则：
equals，就必须重写hashCodehashCode和equals进行判断，所以Set存储的对象必须重写这两个方法hashCode和equalslist.size()<? extends T>来接收返回的数据，此写法的泛型集合不能使用add方法，而<? super T>不能使用get方法，作为接口调用赋值时易出错Comparator要满足如下三个条件，不然Arrays.sort，Collections.sort会报IllegalArgumentException异常
| 集合类 | Key | Value | Super | 说明 |
|---|---|---|---|---|
| Hashtable | 不允许为null | 不允许为null | Dictionary | 线程安全 |
| ConcurrentHashMap | 不允许为null | 不允许为null | AbstractMap | 锁分段技术（JDK8:CAS） |
| TreeMap | 不允许为null | 允许为null | AbstractMap | 线程不安全 |
| HashMap | 允许为null | 允许为null | AbstractMap | 线程不安全 |
ScheduledExecutorService则没有这个问题CountDownLatch进行异步转同步操作，每个线程退出前必须调用countDown方法，线程执行代码注意catch异常，确保countDown方法被执行到，避免主线程无法执行至await方法，直到超时才返回结果ThreadLocal无法解决共享对象的更新问题，ThreadLocal对象建议使用static修饰if (condition) statements;if (condition) {
...
return obj;
}
// 接着写else的业务逻辑代码;
