try{
//代码区
}catch(Exception
e){
//异常处理
}
代码区如果有错误,就会返回所写异常的处理。
首先要清楚,如果没有try的话,出现异常会导致程序崩溃。
而try则可以保证程序的正常运行下去。
Java的异常处理是通过5个关键字来实现的:try,catch,throw,throws,finally。JB的在线帮助中对这几个关键字是这样解释的:
Throws: Lists
the exceptions a method could
throw.
Throw: Transfers
control of the method to the exception
handler.
Try: Opening
exception-handling
statement.
Catch: Captures the
exception.
Finally: Runs its code before terminating the
program.
