写个数据库连接怎么会内存越界呢。。

报错 ：
java.lang.ArrayIndexOutOfBoundsException: 0
at oracle.jdbc.driver.OracleSql.main(OracleSql.java:1661)

求大神~~~~
[解决办法]
oracle.jdbc.driver.OracleSql.main(OracleSql.java:1661)
这个应该是你测试类里面报错的
[解决办法]
你确定代码全贴出来了？
这段代码是没问题的
[解决办法]
看了下代码没有问题 main方法中只是单纯做连接便获取connection对象 并没有做任何操作 不存在问题... 并没有执行到public int executeSQL(String preparedSql, String[] param) ,应该不会报数组越界。。。。
[解决办法]
如果用的是Oracle11的话，有一个版本的驱动有问题的。
