今天在调试某个问题的时候,由于使用了很多循环,我需要都打印出来,试图使用clob整体处理之后再打印. 最后抛出此异常:数字或值错误. 网友解释如下: $ oerr ora 650206502, 00000, "PL/SQL: numeric or value error%s"// *Cause: An arithmetic, numeric, string, conversion, or constraint error// occurred. For example, this er

异常处理机制 异常处理是对可能出现的异常进行处理,以防止程序遇到异常时被卡死,处于一直等待,或死循环. 异常有两个过程,一个是抛出异常:一个是捕捉异常. 抛出异常 抛出异常有三种形式,一是throw,一个throws,还有一种系统自动抛异常.下面它们之间的异同. 系统自动抛异常 当程序语句出现一些逻辑错误.主义错误或类型转换错误时,系统会自动抛出异常.如: public static void main(String[] args) { int a = 5, b =0; System.out.p
前提: 当在程序测试时,如果你需要定义一个自己的异常,而非现在已经存在的异常,这个时候你需要用到throws和throw,try-catch只是一个简单的捕获异常的过程. 代码如下: package org.axc.com.Action; import java.lang.Exception; public class TestException { public static void count(int x) throws MyException{ if(x>0) { throw new M
