jdbc实现连接数据库并查询该数据库下表名

package com.git.rdp.utils;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.ArrayList;
import java.util.List;

public class JdbcUtils {
	public static void main(String[] args) {
		Connection conn = null;
		String className = "oracle.jdbc.driver.OracleDriver";
		String url = "jdbc:oracle:thin:@192.168.1.150:1521:orcl";
		String user = "devplat";
		String password = "devplat";
		String sql = "select table_name from user_tables";
		try {
			Class.forName(className);
			conn = DriverManager.getConnection(url,user,password);
			Statement stmt = conn.createStatement();
			ResultSet rs = stmt.executeQuery(sql);
			List<String> list = new ArrayList<String>();
			while(rs.next()){
				System.out.println(rs.getString("TABLE_NAME"));
				String tblName = rs.getString("TABLE_NAME");
				list.add(tblName);
			}
			System.out.println(list);
		} catch (Exception e) {
