分析以下代码。public static void test(string ConnectString){System.Data.OleDb.OleDbConnection conn = new System.Data.OleDb.OleDbConnection();conn.ConnectionString = ConnectString;try{conn.Open();…….}catch(Exception Ex){MessageBox.Show(Ex.ToString());}finally{if (!conn.State.Equals(ConnectionState.Closed))conn.Close();}请问1)以上代码可以正确使用连接池吗?2)以上代码所使用的异常处理方法,是否所有在test方法内的异常都可以被捕捉并显示出来?
分析以下代码。
public static void test(string ConnectString)
{
System.Data.OleDb.OleDbConnection conn = new System.Data.OleDb.OleDbConnection();
conn.ConnectionString = ConnectString;
try
{
conn.Open();
…….
}catch(Exception Ex)
{
MessageBox.Show(Ex.ToString());
}finally
{
if (!conn.State.Equals(ConnectionState.Closed))
conn.Close();
}
请问
1)以上代码可以正确使用连接池吗?
2)以上代码所使用的异常处理方法,是否所有在test方法内的异常都可以被捕捉并显示出来?

给定以下代码,以下哪句是正确的? public class Test { String s; static class Inner { void testMethod() { s = "Hello world."; } } public static void main(String[] argv) { Inner i = new Inner(); i.testMethod(); System.out.println(s); } }A.编译通过,但是运行时刻出错,因为s没有被初始化B.无法编译,因为Test类里的String s不是static的C.编译通过,打印出Hello world.D.无法编译,因为Inner不能像这样在main中使用
