抛出异常,让调用者捕获异常

So,how do we know that some method throws an exception that we have to catch?
Just as a method must specify what type and how many arguments it accepts and what is returned,the exception that a method can throw must be specified.the list of thrown exceptions is part of a method's public interface.The throws keyword is uned as follows to list the exceptions that a method can throw:
void myFuntion() throws MyException1,MyException2{
//code for the method here
}

抛出异常，常和Try搭配使用，也可单独使用
|
抛出异常,让调用者捕获异常。
|
抛出例外 (此例外不再考虑，或其他程序处理)

当有异常出现时，本身不做处理，抛出异常,让调用者捕获异常
