测试oracle连接池最大连接数，这样有什么问题吗？测试中一直没报错。

Java code

import java.sql.Connection;import java.sql.DriverManager;import java.sql.ResultSet;import java.sql.SQLException;import java.sql.Statement;public class JDBC_Test {    public static void main(String args[]) {        Connection connection = null;        Statement statement = null;        ResultSet resultSet = null;        try {            String driverName = "oracle.jdbc.driver.OracleDriver";            Class.forName(driverName);            String url = "jdbc:oracle:thin:@127.0.0.1:1521:orcl";                for (int i = 0; i < 1000; i++) {                System.out.println("连接到oracl成功!----"+i++);                connection= DriverManager.getConnection(url, "bschis", "bschis");                statement= connection.createStatement();                statement.executeQuery("select * from EHR_HealthRecord");                }            } catch (Exception e) {                e.printStackTrace();            }    }}

但是如果换成数组的，就ok了！如下：

Java code

import java.sql.Connection;import java.sql.DriverManager;import java.sql.ResultSet;import java.sql.SQLException;import java.sql.Statement;public class JDBC_Test {    public static void main(String args[]) {        Connection[] connection = new Connection[1000];        Statement[] statement = new Statement[1000];        ResultSet resultSet = null;        try {            String driverName = "oracle.jdbc.driver.OracleDriver";            Class.forName(driverName);            String url = "jdbc:oracle:thin:@127.0.0.1:1521:orcl";                for (int i = 0; i < 1000; i++) {                System.out.println("连接到oracl成功!----"+i++);                connection[i] = DriverManager.getConnection(url, "bschis", "bschis");                statement[i] = connection[i].createStatement();                statement[i].executeQuery("select * from EHR_HealthRecord");                }            } catch (Exception e) {                e.printStackTrace();            } finally {                    }    }}

这是为什么呢？不知问题在哪里？

补充：
对于hibernate 如何获得当前连接数呢？

探讨
Java code
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class JDBC_Test {
public static vo……

LZ可以好好学习下java的垃圾回收机制
